I’ve been waiting the entire rest of the year for this. Will be here!😂
One of your best informative videos. Just a quick question. What type of warranty is provided by your company to the customer of this rebuild? Also, if there is a warranty claim, would your company assign the repair to you or whomever did the initial work? Thanks in advance.
Turns out using silicone is professionally recommended. Finally it comes out 😂
Josh sent this video to a friend who works on the same equipment. I asked him if he pulled the cooling package. He has done that and stated it took 2.5 hours longer to do the same job. So yes, you were right on how you did the job. He has been a mechanic on Cats for 25 years. The marks that you saw on the cover is normal on that engine, according to my friend. He puts a very light coating of black atv smoothed out on the covers. He was very impressed as to your mechanic abilities and said he wiil start watching your videos.
I absolutely love gear driven engines and machines. There's something so elemental and beautiful about seeing them turn in perfect harmony. I work in industrial maintenance and the days that I get to spend rebuilding certain pieces of our equipment at the plant are so fun, they don't even feel like work.
Those ECMs are also a joy to pull off with everything on the engine
these, and the graders from the ports were always my most prideful loads to haul around on my lowboy loved it because it was always a challenge trying to get reaccustomed to the steering lol
4:30AM. Bless all you fine people who keep the world running while we sleep.
Well that's not every week, we were working longer hours than normal last week.
Who is “we”… same time we start.
Have you ever used anaerobic sealant as opposed to gray RTV? That's what I've used in the past doing front/rear gear housings when there was wear on the block or housing. It doesn't dry unless it's removed from air so any excess that squeezes into oil passages is just washed away by the oil. Much less chance if chunks of it ending up where it doesn't need to be.
That's a good idea. I've had silicon leak after a while. Thanks for the tip.
Great comment was thinking the same thing he kinda said it with out saying it exactly but he definitely didn't agree with that decision.
I personally always use anaerobic sealer, never had a leak after! I like it way better than regular RTV sealer.
Only thing I don't like about anaerobic is it dosent flex or move once hard, so for dissimilar metals are a no go, but just my opinion
@@beekerscustoms That's not 100% true, Loctite even advertises it
Man, that C18 sounded so crisp at idle. What a beauty ! And that's coming from someone that prefers the Red Kool-Aid under the hood. 👌😁
Great job, Josh ! You're killing it. 👍
I loved it when you stumbled and dropped those torques faced bolts into the trash by accident lol ! I do not like them either ! Great video ! Thanks
My favorite part is that CAT song Lynyrd Skynyrd meant to write "Hoo-hoo that sound, Can't you hear that sound". That C18 in my Kenworth T880 would be a good marriage - "Dreamin', I must be dreamin'".
I'm glad the "William Tell Overture" music has made a return. 👍
Nice Christmas present for my 379 a fresh c18😁😁
Never seen anyone checking backlash with a feeler gauge before. Works great on that application! Great tip.
That’s what I was taught. How do you do it?
Magnetic base and a dial indicator.
I prefer the feeler gauge
When I was a truck driver I only used water for a coolant all year round every year we ran the truck. We didn’t have any issues whatsoever doing this. I guess because we had a driver on the truck in the day-shift and then a driver in the truck on night-shift . The truck never had a chance to cool down except when it was in the shop for service and any other reason . In two years we had over 850, 000 thousand miles put on it .
The reason the timing mark on the bull gear (accessory drive) wasn’t lined up with the crank timing mark is bc of the different size gears. Cat has an equation somewhere I found and they eventually line up every I think 21 revolutions?! I’ll have to look it back up. Which you may know that as well. Just some useless information 😅thanks for the videos though. They have helped me a lot. I am an owner operator and do my best to work on 99.9% of every aspect of the truck that needs fixed. Unless it’s a warped frame
Had to comment, I'm 99 percent sure I have the exact same in/lbs torque wrench you showed in the video. It's an older snap on with the 1/4 drive head swapped out for a 3/8. I bought it in new old stock condition from a snap on guy who was retiring years ago. The ratchet head was externally tig welded so it would only torque, not ratchet. (Apparently he used it to demonstrate something?) I ended up carefully grinding the small weld away and putting all new guts in it and have used it to torque many camshaft caps since. Older guys I've worked with would always comment they were surprised to see someone actually using an inch pound torque wrench. If I remember I'll post the model number here, it looks identical to yours with the locking adjustment handle.
I use seeverap inch pound torque wrenches, have a wheeler fat wrench and a Carlyle digital
I like the idea of changing the bolts out for the peanut cover😊👍
That kimball Midwest torq CB is the bomb 💣
Got your DOTW music back 😂
Thank goodness. The silence was awkward.
Good to see it going back together
I don't see a problem with ultra gray on the front backing plate, as long as it's not excessive to the point that squeeze out can plug oil passages. The key is a real thin layer
I agree, I feel better putting a thin layer on there than leaving it as-is since we were reusing the backing plate. Those oil passages run pretty close to the seal, so I put it on pretty thin there.
One would have thought that maybe some dowel pins could have been a good idea on that front plate lot of weight swinging up front vibration and all just a thought
One way to limit squeeze out problems is to put a thin bead on then leave it to cure before putting the part together. I am a bush mechanic so correct me if I am wrong but I have done it and it worked well. Jeff
Anaerobic sealer like Loctite 518 is very nice to have sometimes. It's very forgiving as far as assembly time goes, and excess squeezeout isn't really a concern because the sealant only cures when 2 conditions are met: 1)in contact with metal and 2)in the absence of air. If you have an assembly that is large, cumbersome, or has a lot of surface area it can be stressful to assemble quickly enough with RTV....anaerobic sealer gives you as much working time as you need! I love Loctite 515/518, i have the accelerator spray for it as well and i've never had a leak so far. I've used it to seal motorcycle case halves, sump covers on small engines, drive motor/chain case on skid-steers, truck axle flanges, and more.
Thanks again for another educational and entertaining video !
Have a great weekend thanks for sharing
Quite the project Josh. Great job!
Starting your day at 4:30, jeez man.
I do so many leak complaints, I hate them with my heart and soul but I gotta do what I gotta do. Sealant is amazing, there's things rhat come by where no gasket seals and you jave to improvise. Had great succes with the threebond 1104, and threebond 1215j gray and black (depends on what I find first)
I like Threebond too, I have used it a lot on motorbike engines. Use it sparingly though with a very small hole in the nozzle. Jeff
Great video as usual Josh. Can't wait for the live stream
Good sounding Cat, purrrrring rite along!!!!!
I have that same wrench and the plastic case ,it's awsome
Oh good thanks
Like your videos 👍🏼👍🏼
Good video
YES!! I hate pinning the engine in those things. Can't remember what I was doing the last time I pinned one, but the repair was far quicker than just getting to the pinning hole.
Awesome josh and just a note id watch you do a over head 5 hours long because you know what you are doing. I have a dt466e in a international 4700 going to make a video yah its gonna be a long video lol
“Oops!! Ah man. Tripped there…”
Literally laughed out loud. Lol 😂
Happy Thanksgiving legend.
May want to get your torque wrenches calibrated sometime (?). Don't know how well they hold up... Great videos, thanks for the great content!
That’s crazy that they have all the valve lash adjustments in 1 document. It’s all over the place for 35 and 3600’s.
12:56 for the screaming goat on discovery
I bought my 3/8 in-lb torque wrench off the snap-on truck around 1996. 😂
I'll second your thoughts on engineers. Worked with one that insisted the bolt size was the required wrench size. Drove me nuts.
Just like pinning a 3126 PITA
I asked this question on one of your other videos. However, here is more appropriate.
I have a '05 379 with a c15 Acert, being told that my front cover is leaking. (Over 2 gallon in 12,000 mile change interval)
Wanting to know what the cost of labor should be.
I enjoy your thoroughness & I'm learning a lot. Thank you Sir!
I havent worked on trucks in a while and that was a short time but id be willing to bet 10 hours plus coolant plus oil and since you drained the oild change the filter also
C15 peanut cover bolt # 9L-8925: 5/16" HEXAGONAL FLANGE HEAD BOLT
This channel is fantastic, I just started as a power systems tech at cat. Love seeing the similarities! Also…part number for that torque wrench??
👍
😎👍
Man, why the hell you there at 4:30am lol how much they paying you 🤣
there is some truck apps where you need those peanut cover screws to clear brackets
So we are not the only one's that call that a Peanut cover.
Hey buddy, I could start shipping you all the peanut cover bolts that I toss in the metal hopper. Even brand new ones out of rebuild kits. How many have you had to weld out? Worst one I had, was all 12. I try a air hammer first and see if I can get it to move.
I have used 12 point bolts, bolts like your using (3208 oil pan if I recall), lately just using a regular bolt with two hard washers.
You are correct on the stub shaft alignment hole. I took a metric bolt and smoothed it down. Fits really snug with no movement, yes overkill. But I start at dead center. On the cam gear, I cut the head off of a bolt and use it for alignment.
Since I am old and falling apart, I use rags and lay over the idler gear. Dropped more than one bolt in the gear train and decided I am not a good bolt fisherman.
Here is a question that puzzles me. Why does the crank gear and the bull gear have timing marks. As the rest of the gears up do not?
Hi josh, Thanks again for another great piece of content! I have a question for you... why do you set your torque adapter 90° from the torque wrench?
Thank You !
@AdeptApe, what is your favorite paint pen for marking bolts? Thanks so much for your videos. I may have some work for you someday.
Could you do some videos on tier 4 emissions systems??
Was that a Cat product,sealant?
I agree with JasonT nothing wrong with using it in that application. Komatsu uses a similar product both internally and externally in their engine assembly instructions.
Does your shop or do you recommend doing an engine flush after opening up the top end of the engine like you did in this video? I'm company does 50 hour engine oil flush when ever we open up the engine, I don't see how it can hurt but also I don't see how it can really help.
Especially since nobody does Engine oil flushes during breakins of these engines when the engine is going to have a majority of the contamination in the first 500 to 1000 hours. And if you run a machine 50 hours with contamination.
It is possible to do damage in that 50 hours depending on what the contamination is.
Why don’t they use lock wire bolts for critical assemblies? Extra step but very low probability of backing out.
25th from Barstow
Have you ever worked on any other mining equipment? We had a few Cat engines in our crushers and screeners.
I prefer to use 3/8 over 1/2 and 1/4 sockets, it is if the 3/8 sockets work better

Do CAT dealers provide you the engine specific tools? For example that front seal installer. Or does the technician buy their own?
Hello I work for a cat dealer in Texas and most if not all of the tooling is provided by our dealer. The only tooling you would have to buy is something that you would like to use as your own like c7 injector removal tools, for some reason those tools get damaged really easily lol😂
The store pays for it. Some guys will buy certain small engine tools (barring tool and timing pins are the most common) occasionally.
I have seen a head that bad. I was driving an 88 IH 9300 that swallowed one of the intakes off of #5 of course I ignored the issue as I had a bigger problem than that brewing up. My boss was outside when I got the truck back to the shop and he was like did you put a bunch of rocks in the crankcase. I said no she's started running rough after I dropped the load in Streator I know she's hurt pretty bad Barry. He goes back her into bay 1 I'll have Wyatt the engine specialist look at her in on Monday morning. Like what do you mean running rough I go no turbo boost 2 cylinders a pronounced miss and she's not wanting to cool down at all. When they pulled her down head 3 of hat Cummins was Cracked into 3 pieces with all the valves missing on #5 #1 had blown the injector tip off and burned a hole thru the piston and wrist pin into the connecting rod #2 had destroyed rings 3 and 4 and 6 where damaged but looked normal. Truck was running a 444XT Cummins that had run for 3 hours redlined in 13rh gear getting me home expedited with an escort from the cops. Bossman routinely gave around 5K a year to the ISP trooper charities and had called in a huge favor on that day. Why do hard and fast called my mother had a massive heart attack and was not at the time expected to leave. It was so bad that my brother at the time scheduled for a 3 month deployment to Saudi Arabia had his orders cancelled and was put on leave to get him home.
Detroit red gasket maker and send jt!
Hey, very interesting and good all the work you do, but I have a question: that workshop where you work is 24H?? It's just that I've seen on more than one occasion that you record your work in the early hours of the morning. Keep making such high-quality content. Greetings from Cuba 🇨🇺
It isn't 24 hours, but if it overtime days we will generally start pretty early around here.
@@AdeptApe I really appreciate all the videos and information you share.
What marker do you use for marking bolts? I can never find a good one
I use the KT Industries paint marker, it works pretty good.
Bright Mark or Brite Mark, forget the exact spelling on it, but those are the ones we get and I get a lot of use out of them.
@@AdeptApe awesome thank you. Love the videos. I work at a bobcat dealer in Michigan. Keep up the awesome videos dude
Hey thx for the videos wanted to know are you in BC ,
Cummins front plate has a metal I call it spacer they call it a gasket with just a really thin rubber piece that actually is glued to the inside of it and what I always do in the bottom 8 inches on each side of that plate I will take black Permatex and rub a thin layer on that with my hand because what actually happens is the rubber separates from the metal and that causes an oil leak so I actually take the metal part of the the gasket and I put a super thin layer of black RTV on both sides and I let it dry before I assemble it I've never had an oil leak on one of my trucks since I've been doing that from the front cover so in certain circumstances it's good to use RTV but you use it sparingly if these companies would actually make a real gasket rather than a stupid metal piece with a rubber o-ring glued to it you would never have any problems but they choose to go to the rubber o-ring route in O-rings get hard because rubber and oil do not mix together and eventually it hardens the seal and it causes it to leak I miss the old days when we actually had real gaskets out of real gasket material
If you look close the “wear” is the area that is not sealed inside the gasket, ..
My Question for you is about Engine Balancers Do they need replacing, it seems nobody does ??
Yes they do, and your correct most don’t until it wrecks something and even then some still don’t as it wasn’t the balancer that broke.
What is the part number for the bolts you put in the peanut cover i would like to change them on the truck im working on
I've never really worked much on a cat, so is the cam in the head then and not in the block like a cummins?
Does CAT supply you with your tools or do you have to buy them?
It’s some of both, most of there regular tools such as wrenches and sockets are up to them to supply meanwhile specialty tools are owned by the shop and checked out to the mechanics. Obviously some mechanics buy there own specialty stuff as the shop supplied ones tend to not be treated very well. The cat dealer near me gives the mechanics a tool allowance for the stuff they have to supply themselves, I imagine that’s probably common across the board.
Any thoughts on using sealants like Hondabond? Works way better than RTV when trying to seal two pieces of machined metal together.
A lot of honda people say hondabond is the very similar to the ultra grey rtv.
Whats the deal with working at such ungodly hours? Like what does that help?
i never realized before that u are not your own boss, josh. i'm curious how the shop allows u to make youtube videos? i know u do all the editing and narrating when u are off the clock but, i'm sure all the filming u do adds extra time to every job that could otherwise be spent making money for the shop. so what is your arrangement that causes them to allow u to do this? i know this is a very nosey question but i'm just generally a super curious person. lol
The shop he’s at likes his CZcams presence and gives him cat merch to give away, it’s good publicity and gets them business from around the country because people drive to Idaho just to have him work on there stuff.
Dude, what are you doing in the shop working at 4:30 AM? Kind of insane hours for a mechanic? 🤷🏽
As least its not a ISX 😅
If cat will warranty it for a year then rtv is their choice, on day 364 it better not leak or they can eat it.
Cat engineers are high if they think I’m not putting silicone on my engine.
Me first
745= China built cat. There total lemons.
Don’t know about the China part, but I would believe it, perhaps even a China/Fiat collaboration? The “ Lemon” part is spot on. Cat is and has always been #1 in My book, but sure messed up on this one .
Why do you have to swallow so loud? Sip on some water or move your mic away.
Why do you whine like a petulant child,
Well that was a big truck good job bet its cooling down over there in Idaho might have to put the bike away for minute or two...
Those ECMs are also a joy to pull off with everything on the engine
Yes they are a blast. I'm sure they could figure out a better way to pin those engines, other than "screw the mechanic".
