Hands down the best Saginaw rebuild video on YT.
33 min into Video. Anyone who is going to Rebuild a Steering Gear Box need only to watch this YT. Take a week, watch a little each day. VALUABLE information is contained inside.
Update: thanks to this video and another one, I got mine fully rebuilt. So thank you!
Great to hear!
I’m a big fan of magnets in the garage. When I did this using your video, I stuck some small square neodymium’s on the housing next to the piston as pulled it out. Any bearings that were loose stuck to it instead of rushing out. Thanks for the help rebuilding my steering box!
I really appreciate this video. I tried to watch a few others but the over the top personalities and secondhand embarrassing jokes and hard to digest dialog was just too hard to follow. This is straight forward and no bullshit. No bullshit. Thanks a lot.
Thanks for taking the time and posting such a thorough video. I’m about to do the Durango to TJ swap with hydro-assist. Planning on doing everything myself so I’m sure I’ll be coming back to this video.
Just came to say this is a great video. Started on a different one and it skipped a few critical reassembly steps. Then I found yours- wish I would’ve started here. Thank you for taking the time to do this right.
Thanks, very thorough and detailed.
Good angles with the camera and all. I have the confidence to try to not mess up mine and hopefully save myself a few hundred dollars.
Thanks for another thorough and great video! It's timely for me. Ordered my seal kit and bearing today.
Excellent detailed video. I followed it today for a rebuild. Everything went smooth until I was ready to put the spool valve and worm gear back into the housing. The step to put the thrust(flat) bearing was missing. I reviewed that point in the video 5X and it was never mentioned, so I backed up to the beginning to see where it was removed from, and this let me know where it went during reassembly. This video is one of the best I've ever used for a complex process. The next one will be easy.
Wow, I can't believe I didn't show that. I'll have to go back and look. But good idea going back to the beginning.
I am your subscriber, sir. Please ask how to modify the Torque Rod in the Pinion Gear? . All this time I have been observing why no one has modified the Pinion Gear. The info is that by modifying the Pinion Gear you can lighten the steering. Thank you very much in advance, I am waiting for your answer and vlog
It is not recommended by most because the gear already has a lot of miles on it. Very rarely can that truly fix an issue. It must be done in small increments or you can cause it to bind up.
@@TheBFHGarage Thank you in advance for your attention , but sorry for your answer , i don't understand what you mean ? Can you explain what you mean further ?
Very good video, easy to follow, and stuck to the subject matter w/o any rambling. Very much appreciated. Thank You!!
Thank you so much for posting this. Glad to see the part with the hose clamps and the zip tie... Made it a lot easier. Mine was a bit older (67 Chevelle) but it was close enough to make it work.
Thanks for the great video. Just used this to rebuild the steering gear in a 97 Astro van. Couple of things are different in the Astro. Apparently it has a reverse steering box, which took me a couple of tries to figure out that you have to add the balls with the piston starting at the outside instead of all the way in. When turning the input shaft counter clockwise on the Astro box it moves the piston in instead of out. After 2 attempts to add balls starting with the piston all the way in (the input shaft only turns clockwise from there once you get a couple of balls in) and dropping the balls into the bottom I finally figured it out. The other thing that was different was that the dust seal on the pitman shaft was on the outside of the snap ring when I took it apart. It is the orginal box (bought the van new in 97) and the service manual also shows it that way. Hope this helps the next guy that uses your awesome video on an Astro van. Thanks again.
Yeah there's a bunch that are different like you described, but your input here is really appreciated and hope it helps the next one. Thanks!
This is great! I tried re-building one years ago before there were good videos on CZcams and I couldn't comprehend the directions (after all the ball bearings fell out). After watching this video I'm certain I could do it correctly and avoid buying a poorly done reman. I've returned multiple re-manufactured units to the local auto parts stores.
Great video. My son's 98 TJ box is leaking, I am going to have him watch this video so he can rebuild his box and save himself some money over buying a reman.
As I'm about to rebuild the steering box on my Winnebago I've watched numerous videos on how to rebuild it. I will just say you set the standard and will be the video I use when I pull mine apart. Excellent narration and the videography was superb. I've always said a good instructor can take a difficult job and make it look easy. I look forward to watching your other Jeep videos since my CJ8 needs some love.
Good luck with that project! The thing I don't like about videos is that they don't show the frustration the teacher encounters, and it does happen. Just be prepared for anything that doesn't go smooth and stick with it without losing your cool! Reinserting the ball bearings can take several attempts to get them all in.
Very informative and the comment for thrust bearing is good to remember from the beginning.
This has been so helpful, thank you for the info, details and quality.
So detailed and at a great speed to follow along. Great camera angles to allow full visual of which step is which
Just got the rebuild kit from Midwest military. Gonna tackle this when I get it
Great in depth gear box full rebuild. Nice tricks of the trade reviled.
While I had everything apart I used 2000 grit to polish all metal parts for easier fluid flow. Even did the grooves on the worm gear shaft. Man does my steering work flawlessly now. Don't know if my polishing made a difference but I would like to think it did. Took me an entire day to rebuild and polish but in my mind was worth the extra time spent. What made me polish the internals with 2000 grit is because I did the same to power steering pump when I rebuilt it. Maybe a combination of both.
Thanks for the video.
Subscribed...
Is there any place that selles the Right bearings? None of the kits have the flange on the bearing to seat it correctly. Just wondering for future reference.
Wow you broke that down and rebuilt it like a pro!
I work at the plant that made these boxes from 2001-on after the gun plant closed across town, as an electrical engineer. Thankfully we don't have to load the balls by hand, and we cheat a little bit getting those pesky teflon rings into the bores.
We make other boxes primarily at this point. Like you said, a lot of the time the housing eggs out where the main bearing in the direction the pitman arm travels, and that's where the play usually is, plus in the linkages. The Rack/Pitman Fan interface is usually not lashy unless someone has really abused the box.
I really appreciate the kind words! I also appreciate the additional information about it👍
so if your box has looseness, this rebuild wont fix it
I get to start rebuilding mine today, and this video looks very detailed!
Awesome how to video, you make it look so easy. Thanks.
GREAT vid...most clearly done! i have been to bmw school an porsche factory training schools, never anything as good as this! !!! gonna start mine tomoro
Best vid on CZcams explaining the steps.👍
all i can say is a proffessional job and knowing how to deal with all marks and dry seals to prevent any damage in it 🤠👍👍👍👍👍👍👍👍👍👍👍🌹
Exceptionally well done video. Thank you!
Excellent video! I’m fixing to have to rebuild one myself.
Thank you for an excellent quality and informative video in this steering box and i feel i can not refer my jeeps' bot with out fear, will be subscribing to watch more of your work.
Great video man! Helped out tremendously.
Thanks, very thorough and detailed.
Thank you for making the video!
Excellent video!
Excellent info, thank you!
Thanks for the great video. You saved me a lot of aggravation and time.
Excellent video, thank you.
Amazing job
I get the sense he is experienced speaking to groups, like a course instructor. A lot of people use snap ring pliers incorrectly, most snap rings are designed for right angle pliers. The reason is to eliminate losing the ring. The body of the pliers should be positioned over the snap ring, when the ring comes off the pliers underload it bounces between the pliers and the piece of equipment then falls straight down. Just came to mind watching the removal of the pitman shaft snap ring. Great job sir, I have referenced this 3 times, definitely looking for other videos.
Thanks for the comments but to be honest, I'd do whatever it takes to get those damn snap rings out of there 😂
Ya man. Your video save my ... I have a 2001 Suburban 6.0L with the Delphi box. According to AcDelco and all GM Parts websites, I can not replace the pitman shaft bearing INA SLH 12501/SKF1250 because I don't have one. Had to order it from SKF and get a major seal kit just for the cap gasket. Thank you again.
Very good video
Excellent video, five stars
U took the time 2 give great inside. Gracias
De nada!
Thank you very much for making this video. Beats the pants off a black and white chilton manual anyday!
Great info Thank you!
Exactly what I needed to learn - first time to rebuild- pretty much anything. Of course I had to watch the video a half dozen times. However; I had confidence the whole way through the rebuild. Thanks Ron Staggs
Thank god man
Big help.
The steering is pulling to the right side .hopefully it’s gonna solve the issue .
This won't solve a pulling issue.
Nice vid! Thank you!
Good video thanks!
I think this may be over my head but its a great video.
It's over your head until you watch the video and learn how to do it yourself 👍 that's why I make them. I had to learn too.
Thanks awesome video. My steering gear box is shot I'm trying this rebuild kit..
great video, can a hair dryer be used to shrink the Teflon seals instead of the worm gear clamp method.
You could certainly give it a try. 🤷 The things we learn together!
Just as a suggestion, to protect the teflon seals and also to install them, but some shim stock.
It is available from industrial supply houses like McMaster-Carr in any thickness, sheet size, rolls, and material.
For this job a .004" stainless shim stock would be about right.
Wrap the teflon seals and then use the worm clamps as you did.
To install the teflon seals it helps to heat them slightly in warm power steering fluid and then wrap the stainless shim stock around the part and slide the reals all the way down without any trouble hitting the grooves.
The worm gear and nut with the balls in between with a return tube is called a 'ball screw' in industrial parlance. They must be taken apart and cleaned for inspection using methods very similar to what you used.
However, your use of a tiny zip tie to hold the return tube together in tight quarters was pure genius.
A Duran Comprehensive , excellent
Nice video
Awesome video; best I’ve seen yet. Forgive me if you mentioned this, but did you orient the ball hoop to make sure the colors are still alternating? It seems like you could get the same colors next to one another if you weren’t careful.
Yes I did 👍
Great instructions and easy to follow job. For a 78 K5 Blazer, I intend to change the sector for a 2WD so I can retrofit a cross-over steering. Are those sectors interchangable for saginaw pumps? I mean similar year from a C10 vehicle.
I can't answer that question 🤷
Sir...I don't know if you teach mechanics for a living...but you ought to do so.
....I have 2 college degrees, and I have never seen a better teacher. I thank ya sincerely for teaching me this procedure sir
Thanks for the kind words👍
Great and helpful video. Appreciate the thorough information. I was wondering though you mentioned the koyo 2020 bearing not having a lip or edge and that you would cover how to put it in, but it seems like you used the same type of bearing with the recess or edge when re installing. Is it the same process with the koyo bearing?
Thanks again
The process is the same, just be sure to tap the bearing from the backside to make sure it's snug against the other parts when everything is installed.
I’m using this video to rebuild a 99 Durango steer gear. It should have 3 turns lock to lock or that’s what it had before rebuild. Now it only has two. What do I check?
Great video, if I had only seen this one before I faught with mine The trick of shrinking down the teflon would have been nice to know. If the cap with the spanner nut is not marked is there a torque spec to start with? Also what about the lash adjuster?
The FSM will have a torque spec depending on the box. I've found that wheel the mark you set lines up is just when it starts to get tight. As far as the lash adjustment, I recommend that people leave that alone except under last resort situations. A box that had 200k miles on it can't be fixed by simply adjusting lash. Wear is wear and you can't get around that. People who adjust that lash need to understand that the box probably won't last much longer.
Thank you for the detailed instructions in this video. I’ve got a box from a 98 Durango that I want to rebuild and tap for hydro-assist and install on my 97 TJ. I can find seal kits all day long but I can’t find any bearing information. I’d like to have all my parts before I start tearing it down. Do you have any information that would help me out with that? Thanks
I don't have numbers for the Durango. If suggest trying to call the place or cross reference a parts list.
Once again excellent video. I took a deep look on how you doing it, because I have an issue on a similar steering gear box that I worked on. Everything I did was exactly the same as the video. But, when I put it on the test bench, after a full stoke, the pressure in the casing was so high that the 4 bolts from the cover just poped out of their holes... striped. The bench was ajusted to 1000 psi. The client's problem was a leakage from this cover. I use to work on hydraulic systems, motors, pumps, body valves etc. This was my first steering gear box. I don't know what is the problem at this point. Maybe the piston goes toofar and is open through the housing?
Wow!!! I have no idea, I've never experienced that before.
Great video, and I am almost finished but my Spool Valve does not come apart as it did in your video. The adjusting Nut had a snap ring, which I removed but that nut plus the next piece does not just slide off. Something feels like it is holding it in place. Did I miss something? Thanks
Depends on what your steering gear came off of. This video is specific to a Jeep Wrangler 97-02 although most other early boxes are similar. See if you can locate a factory service manual for your vehicle.
If this is about a Wrangler, it can take some wiggling and manipulation to get it to come out.
Nice barrel on the wall
Awesome video! Thank you it helped me to rebuild the box on my 02 Nissan frontier. I have to ask though, how did you lose your fingertip?
😂.... Kick back on a tablesaw.
After going through my box, with it 100% reassembled, I decided to drill and tap for hydraulic assist. I didn't want to pull the box back apart, so I removed, drilled, tapped and replaced the top cap. When I was removing the front cap (to replace it with a billet tapped front cap), I rotated the input shaft slightly to push the front cap out. While doing this, the sector shaft came out from the worm gear. I thought little of it, and pushed it back in to re-engauge the teeth with the sector shaft. After putting it all back together, I seem to have a control valve issue. My vehicle will only receive power assist when turning left. Attempting to turn right is with great difficulty. Tires have to be off the ground. Will barely turn, even with hydro assist cylinder plumbed into system! Can I get it clocked/oriented correctly easily? Did I break the control valve, or can you lose the control valve on only one side and have a correctable condition? I'm stumped... Thanks for the awesome video! Huge help!
If you use the worm gear to drive out the front cap, then you will most likely have a ball bearing drop into the piston cavity. My guess is a ball bearing is binding you up. I think you are best off disassembling it and then reassembling it.
Perfect
What is the flat thing in the end of the input side stub shaft called? I didn't see it even mentioned in the rebuild. My gearbox is leaking through the hollow shaft and out of this part which looks slightly different than yours but similar. I'd post a pic but not sure how on here.
Tell me what time in the video to look at what you are talking about...
My steering box was leaking power steering so I got the full rebuild kit, currently working on it right now haven’t finished yet but your video said 24 ball bearing. I opened mine up and it only has 22. I’ve never had a problem with the steering it was just the leak. Wondering if I should be worried about putting it back together with 2 missing even if it was already like that.
I know some boxes have a different number of balls. This came out of a Jeep Wrangler. Depending on what yours came out of it could be normal.
Thank you teacher you done a great job !
thx scotty \\\ 97 Blue Tears
Can you point me towards a span er wrench I can tighten the seal on the car. It's leaking from passenger Ford freestar and common on Taurus. A few inches deep pegs needed on recesses
If I find myself needing a tool like this I usually just make it. I focus solely on Jeep Wranglers so I'm sorry I can't be of much help here.
First off, thank you so much for this video. I used to rebuild the steering box on my 2004 Chevy 2500hd. Everything was exactly the same.
For my box, the bearing pitman shaft bearing had a model number of "SLH12501". I was able to find it on the web and replaced it with a new bearing of the same model.
My rebuild kit did not include the small O-ring that went on the thing on the inside of the spool. Not a big deal I guess, but something to note.
The thrust washers on my box were concave (or convex I guess depending on how you look at it). The high side goes away from the spool or towards the inside of the box. They show a picture of a diagram in the a video on CZcams titled "Saginaw Integral Rotary Power Steering Gear Rebuild" at 37:02 if you need a visual reference.
Again, thank you, the video was fantastic and made the rebuilding job super easy.
Where did you buy your rebuild parts?
@Kyle-ev4fk in the description
@Jason-je1of I am looking for the same shaft bearing model, can you tell me where did you get it?
Hello Mike, Great video! I am getting ready to reseal my 664 casting and your video answered almost all of my questions. I have the seal kit and the KOYO bearing BH - 2020. But I also need the small bearing in the upper section of the spool valve as one of the needles is missing. I have been searching the web and cant find that bearing anywhere. Do you know of a source? Thanks again for the great video.
I don't for that one but I'm sure I have an extra used one laying around if you're interested in it. Email me.... Info in about me section
Awesome Video! You really do set the standard for Instructional videos. Question - You explained the differences in the OE bearing vs After market and it sounded like you favored the after market bearing. Then it looked like you used the shouldered OE bearing in your steering box. Did I misunderstand? Which bearing do you prefer and could you include part numbers and/or where you got yours - Please?
I use KOYO bearing BH - 2020. You can source them from anywhere. I'll put the part in the description.
A made in Ga, USA bearing that will outlast the box!
I caught that too. I noticed the spacing between each bearing.
I compared your video to the service manual. The service manual says that the pitman seal assembly should go in this order from inside to outside: Oil seal, Washer, Snap Ring, Dust Seal, Pitman Shaft Boot. Perhaps you don't have to hammer in the dust seal if the snap ring is already in? Did you intentionally reverse their order?
I’m looking to rebuild an 80-96/7 Ford truck steering box, it looks similar to this one. Is this a similar step by step for something like that?
They are very similar but be prepared for any differences. 👍
When your putting the U shaped bearing holder at 1:05:30 What direction do the light colored bearings go in. Does the light color face the large opening or the black bearings face the large opening. Because there seems to be 2 ways it can sit in the two holes.
You want to alternate the black bearings with the chrome bearings. When you install the U channel, use the opposite color bearing that it will be butting up against.
@@TheBFHGarage thank you so much for the help. Without you I couldn’t learn this info in very many places. I don’t have anyone in my life to coach me along the way to fixing things myself. Thank you
I'm curious about sector shaft alignment issues when it's all buttoned up. I need to remove the box from the car, hopefully the wheels will be straight. But when putting it back in the car how do I know if the sector shaft is in the right alignment with the way it came out (to the pitman arm)? Or if the piston is in the correct location...not too far forward or back?
The sector shaft is keyed, so the pitman arm can only go on one way that will make sense. When you are done servicing the box, turn the input shaft lock to lock and count the number of turns it takes. Divide that by two and that will put the shaft at center.
@@TheBFHGarage thanks for the quick reply! I never removed these parts before,,I didnt know the pitman arm was keyed either. Great video. I plan on playing it while I tackle this job.
As for the surface of the housing - How would you go about making it totally smooth? Let's say you wanted to get it real smooth so paint looked really good on it. How would you do it?
I would never waste time doing that. Stock boxes are cast and will be rough. If you want smooth but an aftermarket box.
@@TheBFHGarage Yes this would be for an old classic show truck that gets driven maybe 5k miles per year. I wanted to rebuild the box but I figured why not make it look nicer while I had it out.
This is one of the best videos I've seen on how to rebuild anyting you do a great job. But I have a question for you I have a 78 C30 when I make a right hand turn at an idle I lose my power steering and it gets really stiff after seeing your video the kind of seems like I may have an issue with the balls I'm going to be getting a rebuild kit but just curious what you think
Maybe a bad internal seal but that's a wild guess. I doubt the ball bearings. There is nowhere for them to go unless it is really broken.
@TheBFHGarage thank you I will let you know
Where did you order the bearings? Also what bearing is the other one, besides the BH 2020? I can't find the bearings for this box ANYWHERE ... Just the sealing kits 😢
BH 2020 on Amazon
@The BFH Garage at 1:03:50 you can clearly see the end cap is back on (while inserting the bearings) but at 1:08:22 you put your socket on the service cap to rotate to correct orientation. Did you Install it then remove it and then install it again?
Yes, I got ahead of myself and had to back up👍
@@TheBFHGarage So leave it off until you get it oriented? Cool. I've got a super leaky Saginaw on my '77 Cadillac Coupe. I went ahead and ordered the bearing. Now something that was already mentioned in a question but I didn't see a reply: You said the original bearing has a lip that keeps it from going in too far and the KOYO BH-2020 does not?
@@michaelvincent1 correct
@@TheBFHGarage Is there a way/trick to keep it from going in too far? Your video is great BTW!
@@michaelvincent1 drive it in to flush, install seal, dust shield, etc., and then tap from the back side until it's pressing on the other parts
So sur,
In the event that your dterribg comes out of center in the cab...from ur dteer eherls hitying a curb and throwing ur sterring slignment off, fors the worm gear jump a tooth???
Ty, much appreciated.( all ny ither sterring parts and jounts are good) ty.
Vert der ferk? 😂
The sector shaft teeth are very large. I didn't see how it could jump a tooth. The steering gear would fail in a probable spectacular fashion.
So ehat exactky causes yhe sterring wheel inside the cab to change positioning...ty.
Hi there The BFH Garage, I have a very big doubt , when I check if I have good rotation I turn to the right and is just one round , and turn left and is just one round, I'm not sure but I think that cool be not enough. do you know why?---
What vehicle is it in?
Got a reman from AZoon and it had lash as bad as the old one. Tried to adjust the play again and steering went very weird very unsafe got it bad to just sloppy and live with it. $180 later, I'm soo frustrated. Have another one from ORipme's ready to try. Glad I anti-seized the pit-arm thing.
Lash adjustment is what it is. People think that you can magically make it better. Something that is beat to crap will still be best to crap no matter how you adjust it. You're better off finding one with lower miles or buying a redhead or PSC unit.
Oustanding!!!
Do you have a video to rebuild a Hydroboost unit that used on these steering units? Thank you
I don't
What seal kit did you use? When I look for them, there are many options and I can't pinpoint which one I need exactly. My steering box is just like the one you show in the video. Also, the bearing that I do see in the kits do not have the flange.
I haven't seen an aftermarket bearing that has a flange. The seal kit is listed in the video description box.
@@TheBFHGarage Thanks for the quick reply. When I search that part number on their site, I get no results.
@@user-ge3qi4bw9o That's one of the reasons I don't like adding part numbers to these videos because they constantly change. I would go with what they have listed for your specific application.
I apologize if you mentioned this in the video, I admit that I skipped through just to get the gist: does this help eliminate any center play or is this strictly to address leaks? If not, is it possible to renew the worm gear and/or recirculating balls on these in order to tighten up the slop?
This addresses the leaks for the most part. Worn parts are worn parts no matter how you look at it. The one thing that can help is a new sector shaft bearing. I have it listed in the description.
@@TheBFHGarage Thanks for the quick reply. So does no one supply new worm gears? Or slightly oversize balls?
@@birdrs not that I'm aware of
So why are you against adjusting the lash? What is worn that adjusting the lash solves? What parts am I meshing together to eliminate a sloppy steering wheel?@@TheBFHGarage
@@tim1299 It's not that I'm against it, it's just that adjusting it will rarely solve the problem. A steering gear with 300K miles will be worn and no amount of adjustment will fix that. Adjusting it tends to make it feel notchy and will lead to quick failure as the parts aren't meshing smoothly. Word of caution if you do decide to mess with your lash. First, make SMALL adjustments and test drive. Second, be ready for a plan B (different box).
Awesome!!!! Learned a lot from the video. My sister has a 99 GMC Suburban C1500. Her steering gear box is leaking on the top of the sector shaft where the allen and the nut is located at. Her husband said the nut was loose and when he tried to tighten the allen and the nut, it won't tighten so it still leaks. Is there a gasket on that nut or is it just the sealer that you said to replace? If there's no gasket where the allen and the nut is located at, my conclusion is the sector shaft is broken? Please help and thanks to you and anybody else that can help my sister and her husband.
The allen head is there for the adjustment. The nut secures it afterward. Not sure what he had going on there.
@@TheBFHGarage thanks.
I really appreciate the video. However, the ball bearings from my unit are very hard to discern the black from the silver. The color must've worn off over the years. Can you find out which is which by size?
Yeah some are just that way. You can try to measure with calipers. I've seen others just throw them in without concern.
@@TheBFHGarage Thanks for the quick reply. I think I will just purchase new ones. OEM part is only $35 for them. I have the service manual and it also says to alternate as you showed. I'd rather do it right once.
My calipers were not consistently finding a difference either.
@@TheBFHGarage For your or anybody else's reference, I measured all the balls twice with a micrometer. Half measured 279-279.5 thousandths; the other half measured 278-278.5 thousandths. The smaller pile does seem to look every so slightly darker, which complies with the service manual.
If I pay shipping, how much would you charge to do this for me? I have 97 ZJ.
you mentioned there should be 24 balls mine only had 22 11 of each size . box is out of a 1964 El Camino your thoughts?
Different boxes can have different numbers of bearings and it sounds like yours is different than mine. CJ boxes are different than the TJ boxes.
Does this also apply with the 97 cherokee xj?
It will be very similar
Good evening, very good video...thanks for making it. I am rebuilding a Saginaw power steering gear box with a large 76 embossed on it. I was told it was for my 1977 Jeep CJ 7 with a V8. My question is that upon disassembly I only have 22 ball bearings. I did a bit of research and some folks are saying that International boxes used 22 bearings, but do you have any knowledge on this? The 76 stamping on the case I believe is correct for my CJ 7.
It's a different box than what I rebuilt, so my guess is, yes it's normal. Napa makes a rebuilt gear that uses 25 bearings. 🤷
Thank you for your reply. In my life I have come across things that are contrary to the excepted norm and sadly most places I contact are not overly knowledgeable. I find it funny that there are a couple videos on CZcams that there found only 22 bearings as well, so can you tell me if you ever tried to load more than 25 bearings and if it could be done? I ask because I am hoping you will tell me that it cannot be physically done and that info would help me. Thanks.
@@ironearl69 I would first ask, do you have more than 22 bearings? You can only load as many as it will take, so no, you cannot load 25 where only 22 will fit. If the piston moves to far towards the end cap, then the bearings will start falling out in the cavity behind the piston. You'll know if something is wrong when you are finished. It is important to cycle the steering box several times each way as far as it will go. If everything is smooth, then you are good to go.
Thanks for your thoughts!
Thank you kindly for your reply and insight! Much appreciated. I'm putting it back together and sadly the teflon seal on the power cylinder wanted to fight me and looks like I need another one. The box I am rebuilding is a power steering Saginaw 800 series for a 1977 Jeep CJ. I am sure this teflon outer seal is used in many boxes with that sized cylinder. Can you advise where you could purchase just the seal, not an entire kit? I see readily available are the pitman shaft seals, but I sure hope what I need can be purchased without buying the whole kit. Thanks again.
How do we contact you about the issues we have ? I have a misfire issue that I've tried everything to fix.
Great video, very informative and thorough. How do you properly "clock" the input shaft so the gear box goes back in the jeep in the correct position for the steering shaft? Thanks again.
Before you take it out, make sure the steering wheel is in the straight ahead position. When you're done rebuilding the box, turn the input shaft all the way to one side. Count the number of turns and divide by two. Turn that much should put it really close.
Thanks for the quick reply. However, that is after the gear box is assembled, I was referring to how to clock it when putting it back together, so the flat spot on the input shaft is at the 12 o'clock position relative to the gear box being in the "installed" position. I am thinking it gets clocked correctly when you start loading the ball bearings with the piston all the way forward, and load the balls from the back hole using counter clockwise rotation of the input shaft? @@TheBFHGarage
@@jefreyjohnson4294 there is no need to clock it a certain way. When you start installing the ball bearings it can only go where it needs to be.
Also, here is another "trick" that I tried. Instead of packing the return rail, I put a bearing onto the worm shaft, rotate in counter clockwise a bit, then put a dowel behind the ball and rotate the shaft a bit clockwise. This pushes the ball down into the worm. If you keep doing that you can get all 24 balls into the worm without putting any in the return rail. Adding a bit of power steering fluid with an eye dropper, after a few ball, helps too.
I think that is because you have positioned the piston at the closest position towards the input shaft. Then the grooves in the worm gear are positioning the input shaft at the proper location for the steering wheel to be in the same position as when it was removed. The way I came about this revelation, was starting with the piston in the middle of the worm gear. Fortunately, I realized the issue before attempting to install it. Hope I am explaining knowledgeably. @@TheBFHGarage
I have the 708 Saginaw where can I get a kit I see one from eldmann but it doesn’t say if it is for 708 thanks
Check powersteeringseals.com if they don't then I don't know🤷🏼
Great video, lots of info for DIY . I just rebuild my gear box with video. One thing all my steel balls were one color no black ones , also when done , same preload (set to markings) i get a slight bind up when turning the shaft . Oiled up really good too, any idea what's causing it? Thanks
You might have dropped a bearing into the cavity. I've had that happen and it's very frustrating! That happens when you turn it too far one way when installing the bearings.
@TheBFHGarage installed/feed all steel ball (bottom hole)with piston all the way in , slowly turning/wiggling the shaft till I saw steel ball protruding on top hole , then installed the little C pipe with remaining ball's total of 24
@@rafaelduenas6465 Did you by chance adjust the adjusting nut on the sector shaft cover?
@TheBFHGarage steering gear did have a little play not much before rebuild, maybe worn-out parts. worm shaft had a burnt/brown varnish look to it . Did clean it up to silver looking, everything else locked good
@TheBFHGarage on the adjuster nut , no I did not touch. I did notice the binding starts when feeding the balls , shaft wasn't moving that smoothly/freely. No preload
I used lots of PS oil .
Can worm drive or steal balls be deformed?
Thanks
Thanks again for the great instructions!
Question(s):
43:29 where does one obtain a new bearing for replacement? (Everyone I've found online wants to sell you the whole steering box, not internal parts)
45:16 how does one get that piece back in without destroying the O-ring? I've destroyed two o-rings (so far…) :(
Thanks!
The bearing number is listed in the description. Do a search online to see who has one. Add far as the O ring, be sure to have plenty of power steering fluid in it when you're trying to insert that part. Take your time and don't force it.
@@TheBFHGarage Thanks for the reply, sir.
The bearing listed in the description is for the sector shaft; the bearing I was looking for is the one that goes inside the spool valve and supports the steering input shaft. The sleeve-looking item is the part I was having difficulties with the o-ring. The unit I have is a Delphi, though the instructions you provided mostly worked for it.
Was thinking I might have to go to a GM dealer (with fingers crossed) and see if their parts manuals list it. but thought I'd ask in case you had that part number handy.
BTW, do you know of any sites that might have access to GM's parts manuals?
Thanks again!
@@jbak6892 oh gotcha, sorry about that. Yeah that might be your best bet. I do not know where you could find one or a parts manual.
What will happen if you forget to adjust the preload, where you made punch marks on the adjuster and the lock nut?
Well, I can't personally answer that because I always do! Like with anything else though, such as gear setups, if it's not put back into spec I would anticipate sloppy steering, leaks, or even failure.
@@TheBFHGarage Thank you.
