I forgot to enter, like a dummy - but still put a comment in with my favorite and why 😂 congrats Scott!

Thank you! I greatly appreciate it!

Hey Josh, I’ve had good luck using a little White Diamond Metal Polish or whatever metal polish I happen to having laying around on journals, after sanding. That kinda fills those grooves in. Not sure how long it lasts, it’s probably overkill but, if you put some time into it, you can really get scratched up journals looking nice before tossing the bearings in.

My factory apprenticeship began over 50 years ago. In unit repair the men used 50/50 STP and engine oil for assembly lube. They taught me to use white lithium sparingly on threaded parts after thoroughly cleaning the threads or sparingly on new threads such as spark plugs. I have been working on alloy engines as an occupation or second job ever since. Never had a problem if I took my time and never heard of using white lithium on rods or anything else internal.

Next time loosen the belts up and the front 2 mains will roll in way easier

Can he sue? It would be amazing if he could recoup the loss because from what I hear, the maintenance cost of these engines is expensive.

​@JuniorJunison u can 100% sue Plat rebuild from cat on a c15 is 33k out the door ( i just paid it)

33080, cost mine, 140k ago

Not sure if it’s worth a court battle. Yes it’s a financial loss, but taken time off from the road and probably paying at least a 10,000 Dollar retainer for a good attorney is even more money spent. I had a trucking business and bad service gets written off as a business expense. Just learn from it and do your research before the rebuild.

I agree with you on that, it would be a different story if he charged for cat parts and used aftermarket. This is just a ram jam mechanic who put this motor together, and you’ve got to write it off and know next time put forth due diligence in picking a good shop and mechanic to do quality work.

Yes. I want more mechanic forensics.

Agree! Definitely not too long.

Just push pause and come back to it later. YT will remember your last position.

Very true 👍

he was short of fingers to count ?

Learned that one the hard but yet forgiveable way. In high school mechanics class we tore down a bunch of junk engines and put them back together. I got this old dodge 6 cylinder swather engine that had been dusted. Mixed up the caps when taking them back and forth to the parts washer. Threw the engine back together. Go to try and turn the crank to start putting rods in and it’s locked up solid. That was over 15 years ago and I never forgot that moment.

He was so doped up he didn't know where he was. Hes now probably a mechanic at the BMW dealer down the street.

@@chrisgreig5628probably drunk while working

I bet the mechanic that built that engine believes he is the greatest engine mechanic on the planet. So good he builds engines at the bar every night

Thank you so much. That's the biggest Super Thanks I've ever received as a comment. If you have any questions feel free to email me at AdeptApe@yahoo.com, although I'm not an expert on Cummins. Give your dog a pet for me.

I'm currently doing an inframe on a 8.3 Cummins. It's also a 1998. It was supposedly rebuilt 40K miles before I bought it. I'm finding a lot of crap work was done on it, but nothing as idiotic as what we've seen here today. I've been watching Josh's videos and he definitely has great advice and it's helped me a ton, even though I don't own a CAT engine.

FCbrants, Is there any chance you'd be willing to film your rebuild for those of us who enjoy watching engine rebuilds for entertainment? I'm not a mechanic, but I play one at home. 👍😁

On N14s check the oil pump gear end clearance. 0.008" is max. And brand new pumps. Come at max clearance resulting in low pressure running. Have the housing lapped to bring the clearance to 0.0045" to 0.005"

@@Fucktard2 That's a definite possibility - we haven't dropped the engine yet, still building the "jack stands" to hold the motorhome Very, Very steady, 6 feet in the air, so we can actually drop the engine, Vs. paying $45k + for a column lift system, or cutting the fiberglass rear cap off to get the engine out. So, you haven't missed anything exiting yet. P.S., I'm not a mechanic either, but Cummins has a great service manual & there's tons of info online, so fingers crossed.

They would probably do a better job to be honest

Sadly I think those Indians would have done better. Not perfect, but better. This is horrible work.

Modern machining has a high rate of repeatability, yet having said that would you trust your life on it? Also name and shame let them sue you, See how far they get with that!

Confidence comes with practice.

I get nervous too, there is a lot going on with an engine.

Yes and you have the problems of scale. My rebuilds were with Volvo red-block engines of 1800 or 2000 cc displacement. Still lots going on, but much easier for a skinny kid to handle. @@AdeptApe

@@AdeptApe I rebuilt one several years ago and started it up. Had a tapping noise when I revved it up. Finally I had enough of the guy who was tapping the engine with the hammer. I went around to the other side to make him stop. Nobody was over there, I beat the "Flash" back to the key switch.

I wonder if the mechanic will watch it, who knows.

@@AdeptApe So Florida ? truck repair Anything and I mean anything goes !

Yep definitely agree.

True

Not all main journals have an oil gallery to use the guide tool with, I always push on the tang on those

In the book for a Cummins ISM they suggest that method. After I read that I was amazed and always do it that way so much easier!

Cummins actually makes a tool for rolling main bearings in, it's a brass piece that goes into the oil galley hole on the journal and will assist in rolling upper bearings in, and because it's brass it is a softer metal than the bearing and when used properly will not damage the bearing. On Cummins, there is no oil hole on the #1 main journal, though, so that one is still by hand. The part # for the Cummins tool is 3823818. This tool can be used on almost any of the Heavy Duty sized Diesel engines. It even works on smaller mid-range Cummins too.

Cat makes a tool for that. I have one

Always used a new unused brass brake shoe rivet to roll main bearings. Fit perfectly in the crankshaft oil hole.

The problem is that no one ever names them publicly out of fear of being sued. As if anyone doing this kind of work has the money to hire an attorney to sue them 😂

That's also how I do it.

That doesn’t really work when the engine has one piece (circle type) front and rear main oil seals. Additionally doing that on engines with one piece (circle type) oil seals has a very good chance of damaging one or both oil seals.

Just talked with a guy that just had injector cups done and a bearing roll in done at a cat dealership . Never made it home engine started labouring , stopped to check things out , engine stalled when he disengaged clutch to stop and wouldn't turn over any more engine locked up . Had it towed back and they told him their mechanic put a rod bearing in backwards . 😮 And told him good news absolutely no damage to crank . 😅😅 I've been building cat engines for a lot of years and my question is how much Emery cloth and cocus cloth was used on crank shaft to cover their butts on that one ..lol As far as using genuine cat only parts is far over rated . Common sense tells me a core on parts means parts are being rebuilt ,and that's fine in most cases , but tell me what's better a welded reground camshaft , or a brand new quality jobber cam shaft ? Im finding a quality jobber cam lasting just as long as cat cams . Usually the cam itself is never the root problem of a bad cam in the first place . And what is better quality a head that has had cracks repaired in it , or a brand new head casting ? I've put jobber heads on C15 out on hard service jobs haven't had an issue yet , but once of many reman cat head on a C15 and could hear a slight ticking after firing it up after about 20 minutes of running the hard to hear slight ticking developed , and I found two Broken valve springs both broken at exactly same height / positioning on the coil so obviously a bad batch can show up in OEM as well I've been doing this for 40 yrs and I can honestly say with good conscience. There is good quality jobber parts and many time genuine OEM parts is just an expensive name your buying . But I will say there is some parts I insist on genuine OEM parts as well , because there is some junk jobber garbage out there . But there is also good quality jobber out there as well . So only OEM only is far over rated and myself when there is a core on cylinder liners that almost creeps me out .

Your comment deserves a response. I am the owner of the truck and I am very picky inside and out. I paid for a complete repair including the head. The truck left with many problems from the beginning. And yes, I have been solving them little by little. examples (I had to change the thermostats, full of silicone I had to change all the brake housing too,they never calibrated the truck or they were incorrectly calibrated, (maybe because of the paint or dirt ,low oil code, overheating, code of all the vva valves etc. The truck went from dealer to dealer before seeing Josh. Since June I had been writing to Josh to see where he was working but making appointment with him and going from Florida to Idaho didn't bother me. It wasn’t so easy. When there and I waited almost a week just to talk to the best ,plan everything and make an appointment again in time. (believe me it was worth it, in my opinion great mechanic) cat in Florida no longer serves trucks and many dealers don't have cat specialists, it's a shame but it is what it is . $20k+ after rebuilt sound right to you,there are many things that you don't know and I can't give many details. That's my sad but true story.

​@@adonisbatistaibanez4053I don't think many people can blame you for your actions honestly. You spent good money on a rebuild and as a result you expected good results. You should however consider opening a civil case against the guy who rebuilt your engine, this video is fantastic evidence in your favor

I feel for you the thoughts and doubts when you were finding out these problems would drive some to drink.@@adonisbatistaibanez4053

​@@panzerfaus8459Even though I don't think it is always as to start a civil case easy in real life (besides it would cost more money ahead of only a chance to win and get that back as well) but of course for starters he could lay his consideration of starting such a case in front of the mechanic(s) / shop that did him wrong, maybe threatening that is sufficient to get at least part of the pay back

I work in construction as a supervisor of many jobs. I drive my truck about 65,000 miles a Year and have black stone laboratories analyze my oil about every three changes (15-18,000 miles). This has given me great insight about my engine, the oil I use and the effects of my extended oil change intervals. I pay for the better analysis

This has owner operator finger prints all over it guy who owns a truck as meticulous as that is doing his own rebuild

​@@geauxtigers6369I would think that a guy that keeps a truck as nice as that wouldn't screw himself on an engine job.

@@geauxtigers6369 I thought the same.

I would have liked to do it myself, I think it would be better than what I paid for. The best of all is that I would have saved $50k+ and I'm still not done, sad but true.🤷🏻

@@geauxtigers6369I seriously doubt the owner of this truck did the butcher job on this truck because how meticulously clean as the truck is whereas whoever did the engine work had a very low amount of attention to detail comparatively.

Not by the same kind of person who puts together an engine this way

Maybe the bearings was hard and had to be ground because he hammered numbers into the caps in a press 😂 That’s obviously where he got them out of order.

Him and I planned his repair out a few weeks ago and luckily we were able to get him back up on the road again in only 4 days. Not a productive 4 days for him, but at least he had it planned out and now he knows the condition his truck is in. He is a very nice guy too, bought pizza for the whole shop and was very thankful.

@@AdeptApe Good people are hard to come by these days. Your a good honest professional and that is very rare today, Happy Holidays to you and your family God bless all...

99% of truck drivers that own equipment, Don't have this extra money to throw around, Nobody seems to be talking about that. So he probably spent between 20 and 30000 dollars for the initial rebuild And then you probably charged another $5000 for your time just to go over it. And he had a nice attitude the whole time, Bought pizza, Most guys aren't in the position to do this, So I'm sure this guy probably had an extra 6 figures to play around with And the extra time of not making any money Nobody ever wants to point that out.

First thing came to my mind.

Anyone would be money ahead to be towed out of that area and get the work done somewhere else.

I moved to Florida for a year got fired from a job because I wouldn't do crap work and swindle customers.

Yes it is very good to loosen fan belts, it helps !!👍👍

I used the tiniest brass punch I had to roll mine out. I also used the pocket screwdriver, but only to realign the new top bearings when they started to go a bit sideways.

I have a small bolt with the head ground down that performs the same function. Made it in Mexico and down there they called it the campeón (champion) 😂

Still have mine!!

In this case I’m pretty sure the court is going to make the mechanic give a full refund. That job was not done right.

Anyone who assembles an engine like that isn’t going to cover any costs “willingly”.

​@@markm0000not only the cost of the job, the legal fees too he'll be broke after that

Some of the nastiest, skunkiest, oil that you will ever find! I have to change my shirt after it soaks through. It will stain your skin for a week too!

it is voiceover. he use two audio clip stacked.

Something I never thought of

Dude, you have many miles left in that engine. You're only a little over half way to an overhaul.

Barely run in.😇@@boogieman3165
