Hey, thanks for watching. If you are available on Wednesday the 22nd around 6pm Pacific Time (Night before Thanksgiving), I will be having a livestream and announcing a give-away from Western States Cat! If you wanted to buy one of the serpentine belt tools here is the Amazon Affiliate Link: Serpentine Belt Tensioner Tool: amzn.to/3ugmnZM

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.

4:30AM. Bless all you fine people who keep the world running while we sleep.

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.

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

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'".

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 .

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

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'm glad the "William Tell Overture" music has made a return. 👍

Nice Christmas present for my 379 a fresh c18😁😁

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

Quite the project Josh. Great job!

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 kimball Midwest torq CB is the bomb 💣

Starting your day at 4:30, jeez man.

Never seen anyone checking backlash with a feeler gauge before. Works great on that application! Great tip.

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 like the idea of changing the bolts out for the peanut cover😊👍

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.

Got your DOTW music back 😂

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

Have a great weekend thanks for sharing

Great video as usual Josh. Can't wait for the live stream

Thanks again for another educational and entertaining video !

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

12:56 for the screaming goat on discovery

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)

Good sounding Cat, purrrrring rite along!!!!!

Like your videos 👍🏼👍🏼

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.

I have that same wrench and the plastic case ,it's awsome

May want to get your torque wrenches calibrated sometime (?). Don't know how well they hold up... Great videos, thanks for the great content!

I bought my 3/8 in-lb torque wrench off the snap-on truck around 1996. 😂

Good video

Happy Thanksgiving legend.

Just like pinning a 3126 PITA

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.

“Oops!! Ah man. Tripped there…” Literally laughed out loud. Lol 😂

C15 peanut cover bolt # 9L-8925: 5/16" HEXAGONAL FLANGE HEAD BOLT

I'll second your thoughts on engineers. Worked with one that insisted the bolt size was the required wrench size. Drove me nuts.

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!

there is some truck apps where you need those peanut cover screws to clear brackets

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??

So we are not the only one's that call that a Peanut cover.

😎👍

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?

👍

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?

@AdeptApe, what is your favorite paint pen for marking bolts? Thanks so much for your videos. I may have some work for you someday.

25th from Barstow

Thank You !

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.

Man, why the hell you there at 4:30am lol how much they paying you 🤣

Have you ever worked on any other mining equipment? We had a few Cat engines in our crushers and screeners.

Could you do some videos on tier 4 emissions systems??

Why don’t they use lock wire bolts for critical assemblies? Extra step but very low probability of backing out.

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.

If you look close the “wear” is the area that is not sealed inside the gasket, ..

Harold the Spider

Hey thx for the videos wanted to know are you in BC ,

Detroit red gasket maker and send jt!

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?

I prefer to use 3/8 over 1/2 and 1/4 sockets, it is if the 3/8 sockets work better

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.

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 🇨🇺

Do CAT dealers provide you the engine specific tools? For example that front seal installer. Or does the technician buy their own?

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

Whats the deal with working at such ungodly hours? Like what does that help?

My Question for you is about Engine Balancers Do they need replacing, it seems nobody does ??

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

Any thoughts on using sealants like Hondabond? Works way better than RTV when trying to seal two pieces of machined metal together.

Does CAT supply you with your tools or do you have to buy them?

What marker do you use for marking bolts? I can never find a good one

As least its not a ISX 😅

Dude, what are you doing in the shop working at 4:30 AM? Kind of insane hours for a mechanic? 🤷🏽

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

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.

Me first

Cat engineers are high if they think I’m not putting silicone on my engine.

745= China built cat. There total lemons.

Why do you have to swallow so loud? Sip on some water or move your mic away.

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
