Sector Shaft Adjustment

- Due to recent questions about this, I've added a page to my site. I posted a drawing from the manual that shows the cross section of the box. It's shows how the gears are tapered. www.bluehandsvideo.com/steerin...
I read the description in the manual yesterday, but I was not following it today. Basically, I just wanted to let you see a better example of what it's trying to describe in the text. I was surprised at how sensitive the adjustment was.

The high spot is actually there to aid in the adjustment of the gear box. If you turn it to the "tight" or high spot to adjust the gearbox, you will not overtighten it and have problems with the gearbox locking up. This was more common on manual steering than power. Never adjust them so tightly that you can "feel" the high spot on the gear. If you notice it when turning stop to stop, back off until you cannot feel the difference in the steering wheel.

In other words to take all the play in the center I will have to make it bind when turning. And then I have to adjust it back a little so I feel no resistance lock to lock which means that the center is back to not be as tight as it could be.
I was just thinking as he did this that you could adjust it till it has no play then move it off centre to check if you get play then back again and see if it binds
That’s answered my question nobody else covers. Very helpful. Thank you.
I'm happy to hear that. You're more than welcome!! :) Mike
You're more than welcome! Thanks for watching!!
....just realized I had "adjustment" spelled wrong in the title! LOL

Excellent presentation. Long time I was trying to understand how the adjustments work. Now it is clear. Thanks man .👍👍
You're more than welcome! I'm happy to hear it helped. Thanks!! Mike
This is the best video/manual that is actually explaining and at the same time being able to see what happens. All of the other videos does not explain the relationship between the gears properly. Most of them say like it is some kind of unimaginable complex system, which it isn't.
Thank you very much! I appreciate that. :)
Excellent video! Really helped me understand what was going on inside the steering box when making this adjustment on my son’s Jeep. Awesome. Really appreciated this.
Thank you very much! I've very happy to hear that it helped you. :)
THANK YOU, for keeping the camera on, I was a little disappointed when you said you weren't gonna show the adjustment. Then you did, lol. This is the only video I've found on it. Great description and awesome video, thanks again.
Thank you very much! I've happy to hear that you liked it. :)
Thank you for your efforts.... this video explains and shows exactly what my brother was telling over the phone (long distance) last night. I have excess play in the steering on my '57 Chevy's original manual steering box.

Thanks for uploading this! I read everywhere to adjust sector shaft to help with a loose steering box, but it's nice to know what is actually happening and not just think it's some black magic
You're more than welcome! There are a few different styles of boxes, but this is a datsun truck unit.....same basic principles at work. If you have time to read them, there's some really good info in the comments. Thanks!!
I have worked in many places as a tech, including several dealerships, who had no clue about this adjustment. It helps a lot if the front end is kept in good condition. The "hammering" associated with loose front end parts does untold damage to these gearboxes. Any time there is slack in the steering, movement accelerates until impact, so the "hammering" effect is intensified by neglect. In truth, front end inspection should be part of an oil change, but few bother. Great videos.

Exactly the instruction I was hoping to find. Thank you for de-mystifying my steering box!
You're more than welcome!! I'm happy to hear that it helped. :) Thanks for watching -Mike
BEST ADJUSTMEND VIDEO IVE SEEN FOR ANY STEERING IVE SEEN THANKS
Wow!! Thank you very much, Mark!! I really appreciate hearing that! :)
Mike
thank you for the video I understood really well the way the steering shaft screw adjustment works thanks again
You're more than welcome! I'm happy to hear that it helped. Thank you!!
This vid is really helpful. Now I know the inner anatomy of the steering box, and I understand why my sector shaft has play and how to fix it! If the center section of the gear is so worn that I can't get rid of the play without introducing bind at the outer areas (turn to lock), I know I need a new box. 2003 F150. Thank you!
Thank you! I'm happy to hear that it's helped. :) -Mike
Beware the rebuilt boxes often get new seals and paint and sent right back out without new gears
@@evanwest1929 Thanks for the warning!
@@evanwest1929 Rebuilt parts, in general, have seemed to go downhill.
That was an awesome explanation of how it works and how to adjust it.
Thanks! I'm glad you liked it. :)
i had a TON of play and you'd be shocked at what an 1/8th turn did for my 95 land cruiser (230,000 miles). for me, 1/4 turn caused binding. thank you!
Yep....it doesn't take much sometimes. :)
Great video thank you very much never saw the inside of one of those so it makes all kinds of sense now. Thank you for sharing with us
Thank you very much!! You're more than welcome. :)
Thanks man for uploading video on worm and sector steering system......I can imagine better now...
This page looks to have a good explanation of both types.
www.carbibles.com/steering_bible.html
I think they explain it better than I can. :)
Thanks!
Thanks a lot sir.....

You're welcome.
You are correct about a tiny amount of adjustment. Turning it more than 1/8-1/4 to 1/2 max turn puts too much pressure on the internals. According to my manual.
Yep....it doesn't take much. ;)
Thanks! I'm glad you liked it. :)

Amazing to understand how that works in details.Thanks very much
You're more than welcome! Thanks for watching. :) -Mike
Nice very informative, I appreciate your work and your experience.
Thank you very much!!
Masterfully done! And Kudos to all who are sharing their insight on the box. I have a Jeep TJ and I’m not liking the play. I checked the ujoint and the bearing on the shaft, all checks good. The slop is coming from the box and I’ll use the setting method you showed. I understand better, thanks!
No promises it's exactly the same as this Datsun box, but good luck! I hope it works out well for you. -Mike
I have a Jeep TJ also nd it sounds like we have the same issue. I was going to replace it but now I’m thinking it’s just not adjusted correctly. We shall see.. thanks for the info!.
Great Video! Thanks for taking the time to make and post it!
Thanks! You're more than welcome.
There's some great info from other posters in the comments below if you get a chance to read them. :)
Awesome video on how the adjusting works. I understand so much better.
Thank you! :) Mike

Thank you for this.
You're more than welcome! Thanks for watching. :)
Thanks! I was going to try adjusting that nut anyway but your video really helps explain the inner workings and I have much more confidence now.. Good luck on your HOT ROD...Or mud machine or whatever your building :-)
shadetree mech Sweet! Glad to hear it!! Thanks! :) Mike
perfect video on how it actually works. looks pretty simple in there, not too many moving parts
Thanks! I'm happy to heat that. :) -Mike
You are the man. Sweet video. I am now a follower. lol
Thanks Jon! I'm glad you liked it :) You'll probably find out pretty soon that I'm not currently doing much car stuff. I'm working on parts for old datsun trucks, but not actually on the trucks. I'll get back to the ball joint mod for the truck after I get the brake kits done. :)
Mike
Thank you for making it easy to understand.
Thank you!! You're more than welcome. :) -Mike
This is a great video. Well done. Thank you.
Thanks! You're more than welcome. :)
Thank you.You save me from taking my box apart. Now I know what is going on inside of it. Thank you very much
You're more than welcome! I'm happy to hear that it helped. :) -Mike
Very helpful bud. Now I know how it works makes sense, I was about to thread the adjuster till it bottomed out....thank you
I'm happy to hear it helped. Thanks for watching and taking the time to comment to let me know! :) Mike
Incredible video! Thank you so much!
Thank you! I really appreciate that. :)
The high spot in the center aid In Straight a head steering - not to bind the steering , but enough force to help hold it straight .
Thanks.
Good work its all clear now! Cheers again.
I'm happy to hear that! Thanks! :)
Great video! I’m working on my new project car a 95’ 4Runner and I just replaced an extremely worn idler arm that was causing some crazy slop but after I replaced it it got rid of the play in the arms but I noticed there was still a good amount of play in the steering wheel and found out about the steering gear box adjustment. Lots of videos say how to adjust it but not many explain exactly what’s actually going on in there. Thanks!
Thanks! I find it a lot easier to do adjustments/work when I understand the "behind the scenes" part of it. "Tighten until you feel.......", doesn't usually work for me. lol -Mike
Awesome show and tell, that is the best way to learn how to understand a gear box
Thank you very much!! :)
Great video! Thank you so much!
you're more than welcome. Sorry for the extremely long delay on the response. :(
Helped me understand what I was doing! thanks!
Awesome! I'm happy to hear that! Thank you! :)
very well done, this has helped me a lot..thanks

Thankyou for a very informative and derailed explanation!
Lol
you're welcome. :)
had to read it 3x's to get what was funny. :)
Thank you for making this video. I just bought a used Jeep Cherokee steering gear and used this video to inspect the play. No descernable play in the middle of the range, some play when the pittman is turned to one side. Good to go. I cleaned the steering box, painted it up and have it ready to go into the jeep soon. The previous owner adjusted the sector shaft and it is way too tight.
You're more than welcome. I'm happy to hear that it helped! Thanks for watching and taking the time to comment.....I really appreciate it. :) -Mike
Thanks.
High spots?
I was surprised at how many different steering boxes they have out there. There's definitely some differences. This Datsun one is the only one I've torn into. Maybe one of these days I'll do this to the '64 Fairlane I have. I think a lot of people just think the excessive play is from the design since they're use to rack-n-pinion.....they just accept it rather than fix it. A new box and front end parts make a world of difference!! But, there's no new boxes left. :(

Phucking phantastic! Thanks for an outstanding explanation!
You're more than welcome! :)
Great job of showing what this adjustment actually does.
Thanks!! :)

Nice high quality video for the date posted. I'm going to try again my first attempt I couldn't get jam nut loose.
Thank you! Wow.....sounds like it's really stuck. 6 sided socket and maybe try tightening it just a hair to break it loose. Good luck!!
nice vid. well explained. I learned a lot.
Thank you very much Bob!! There's some really good info in the comments, too. :)
Great awesome video, now I really can imagine what is happening down there that makes my 94 vic play on the lanes :D
Thanks so much Mike you made our ride safer before it is too late :P
You're more than welcome! I'm glad it helped! :)
There's more good info in the comments if you get a chance to read them. :)
Thanks! Mike
You can put the lid on by backing the adjuster back a couple of turns and the whole assembly will go on. Then adjust it right down and back off a quarter of a turn then check the feel on the whole steering left to right. Most old boxes will have some wear in the straight ahead position. If it is too much the gears are stuffed!
Thanks!
Thanks for the input! Great info! In Germany, all cars have to go through inspections and that was something they checked.
I like the "rule of thumb" in your first post.
What is the "high spot" you mentioned?

Ah got it now, great video and saved me opening up my old one to see how it worked :)
Cool....glad to hear it helped. :) Not all steering boxes are the same, but if you're working on a Datsun, this you're good. A lot of the others are like this or have similar adjustments.
Thank you for the video
You're more than welcome! Thanks for watching. :)
So glad I found your video! I've seen several so far that talk about the adjustment, but none that show the inside of the steering box, and what's actually happening when you adjust the sector shaft. I'm looking around right now at vids because my 2009 Dodge truck has some play I want to shore up. I have a question though - Since the most wear will be in the center area, due to vehicles generally travelling in a straight line most of their lives, doesn't it make more sense to adjust this with the steering wheel turned a bit off center, so that you're adjusting at a position with less wear? That would allow you to pull in as much slack as possible without running into a bind situation. It would result in a bit more remaining play at center, but it seems like that would guarantee no binding on either side. (?)
Thanks. I'm not a real mechanic. This is the only box I have any experience with and it was mainly just what I needed to learn at the time. What you're asking makes sense. Maybe another viewer will see your question and have an answer. Sorry I can't help more.
Thank you! :)

Thank you so much sir.
You're more than welcome! :)
Big thanks!! 👍👍
You're more than welcome. :)
LEAKS.... For everyone asking about a leak at the adjusting screw if you don't have the Oring or Copper Washer Seal.... Spray it with Break Cleaner and work it back n forth (in and out), apply any type of Oil based or Oil Resistant Thread or Pipe Sealant. Permatx #1 , #2 or even some Silicone sealant
Great tip!
awesome video , thank you so much , keep doing your videos , very helpul

Cool now I understand these better and am now an expert on the matter 💥😆💥
Happy to hear it helped. :)
good video smart man...
+abdyfe Thanks! :)
Muy buenas clases
Thank you. :)
Thanks you saved me on this video I tighten my too tight didn't know what was going on it wouldn't come back out at the turn the wheel little bit unscrew turn the wheel little bit unscrew
Glad to hear you got it figured out. :)
Yes, steering gear is adjusted by measuring steering wheel free play travel, steering gears will wear from normal use to a point that they should to be replaced.
Thanks. I've never seen a new box available for these old Datsuns. Hopefully, the adjustment will keep it on the road a bit longer. :)
YoU aRe the Man! ...👍👌👌👌👊💪💪💪👍👍👍👍
Thanks. :)
Thank you
You're more than welcome! :)
Real good info....Thanks!
You're welcome! Thanks for watching. :)
the easiest way to adjust that is tighten the adjustment and back off 1/4 to 1/2 turn. That gear box is worn out you might want to look for newer gear box
Thanks! One of these days, I should take all the tips/tricks/advice that viewers have left here and put them all on my site. I'm not a pro at this so there's been some great advice, just like yours, that I could not have given myself. -Mike

This answers a question I had. I have an steering gearbox with excess play. Just been to find he specs to adjust a hd94pab gearbox.
I hope it works for you. :)
@@bluehandsvideo. Oem doesn't seem to be willing to provide me all the information I need so we will be winging the sector shaft end play. They did give me info on interference between sector shaft and power piston.
@@tommysmith8801 The "pinned" post that should show up just under this or at the top has some info that might help. It's by klmartin1962
These old cars call for an alignment spec of 1/2 degree LESS caster on the left in order to compensate for road crown, but that makes the car pull to the left on a flat road, unless...
...the sector shaft adjustment is correct. A proper adjustment calls for the box to be out of the car and to put an inch-pound torque wrench to measure the torque increase as the sector shaft goes over center. IIRC it should be about 10-15 inch-pounds MORE to bring the the box from left turning to right turning.
Properly adjusted, the gearbox is going into a slight bind as it approaches center and the alignment tech can then adjust the steering wheel so this left tendency in the caster is compensated for in the gearbox when it is slightly right of center. No pulling to the right on a crowned road because of the caster, no pulling to the left on a flat road because of the sector shaft bind at center position.
Interesting. I remember hearing about that when I was still pretty young, but I've never come across it on any of the cars I've owned(about 80). Some may have required it, but I didn't know about it or have them aligned. The factory manual didn't say anything about that......maybe the Datsun is too narrow for it to matter? Datsun also doesn't mention anything about adjusting the caster....they say it's fixed. I can't imagine there's too many shops/mechanics around that are still familiar with that. Thanks for taking the time to share that information!!!! I appreciate it!!

Datsun! Now there's a name I haven't heard in a long time!
Yeah, those Jap cars were the first to put McPherson strut suspensions into mass production and their caster is built into the design of the car, it doesn't change as the springs sag when they get older. Dual a-arm suspensions changed quite a bit over the first couple of years until the springs settled in.
We would make the compensation for road crown (and BTW, the car being narrower has nothing to do with that effect) by adding camber to the left side on those cars. Camber pull is the same pull that steers your bicycle, lean to the left, it goes to the left. About 1 degree was the maximum, beyond that and it would definitely pull to the left when going straight, and most McPherson style suspensions also had rack & pinion steering so there was no way to limit that pull with a natural bind in the gearbox like the Saginaw boxes could do.
ladamyre1
I mostly work with the older Datsun trucks.....which have arms and shocks. The caster is built into the kingpin inclination.
I was thinking the road crown was an arc instead of flat and angled(like a roof).....that's why I was thinking the width would matter.
I've always heard about caster and bicycle forks, but I haven't heard about the camber pull. Very interesting! I understand why you'd put the extra degree of camber in(positive I'm assuming) so that it tries to turn up the hill, negating the tendency to go to the right.
What about the scrub radius? Does that tend to pull more as it gets greater? Narrow tires and zero scrub are easy to steer. Wide tires and zero scrub, harder, but not too bad. Wide tires and offset rims(causing more scrub) are a lot harder.......but I only hear it referenced to slow driving/parking.
bluehandsvideo
ladamyre1....I sent you a msg via youtube....wanted to draw your attention to it in case you don't get some kind of notice.
On mine I try to put the cover on and it gives me a 1/2 gap or so ! I tried to hammer it down a bit and won't give
HI, Great video. I seems you are working on a Datsun, funny. My Yamaha golf cart has a very similar steering box. I am going to use your tips when I tear it down this summer. If there is excessive wear, is Pitman arm replacement the remedy? what lubricant is recommended?
Thanks. There's probably quite a few out there that look alike. There may have been one supplier for many manufactures. The pitman arm is the arm between the tie rods and the splined shaft of the steering box. I've never seen one loose on the splines, so I doubt it needs replaced. Of hand, I don't know what lubricant. You can probably find the owner's manual for your cart online somewhere. -Mike
Hmm....I've only done it on the Datsun, so I'm not familiar with the Ford box. I would check it with the steering linkage disconnected from the pitman arm. If it's still the same, I would guess that the box is worn unevenly and you might have to find a middle setting you can live with. Maybe there's another vid on youtube geared more toward the Ford box? Sorry....I wish I had better info for you.

How does this work? Are the gear teeth on the sector shaft tapered?
Maybe someone else will have a better answer, but I think you are correct.
