Is this the first teardown you've seen on this channel? There are nearly 120 more I've filmed over the last two years. You can find them here: • Blown Up Engine Tear D...
Over the last week, I've talked about this week's teardown being out of the box. Well. Its the engine out of a box truck.
A Caterpillar 3126 7.2L Turbodiesel inline 6. This particular engine is out of box truck with over 300K Miles! It was replaced because it ran very poorly, and a mechanic tried swapping some parts around, and eventually condemned it saying two of the cylinders didn't look so great.
The 3126 was a widely used engine in everything from school busses to tow trucks. Power outputs range from 170-330hp, this particular engine is rated at 210hp.
This is Part 1, where I dismantled the top of the engine. Pull the head to reveal the actual condition of the bores we can see. The replacement engine cost the owner of the box truck nearly 8K! Lets hope this wasn't replaced for no reason.
Why am I doing this? I own and run a full service auto salvage business called Importapart. Part of our model is dismantling core or bad engines and salvaging the good parts. We do not rebuild engines, merely supply parts to those that do.
For parts or to peruse our inventory you can visit www.Importapart.com or email us at Importapartsales@gmail.com.
I hope you enjoyed this teardown, stay tuned for part 2 sometime next week!
As always, I love all of the comments, feedback and even the criticism.
Catch you all on the next one!
-Eric

Eric I have a farm boy background which means I did really brutal labor when I was a teen. Now I'm a much older fellow (and not doing farm work 🙂 ) Take some advice...use every tool that makes sense to eliminate any possible damage to your spine. A crushed spinal disk will cause you the most horrible agony until it can be repaired surgically. Use cheater bars, buy better tools, invest in tough tools, anything to save your back, muscles and other bones and joints. I'm real glad you used the forklift to remove the cylinder head. Great video and I hope your back is recovered.

I want to tell you some of the things that I like about your content. 1) Your sense of humor. "Oh this part looks perfect....Yeets it across the room) 2) NO MUSIC Who needs it? music interferes with the narrative. 3) Even the sound of tools is fast forwarded, Very cool. 4) Things break, fall, splash... Included in the narrative. Bonus point for realism. 5) A variety of engines most of us would never see. Keep up the good work.

If that whole integral valve cover harness/injector thing seems familiar, that’s because the injectors are indeed HEUI units. Same as the T444E. As far as I remember the HEUI injector was a CAT design, which they sold or leased (I can’t remember) to IH/Navistar which was then put into their engines which eventually included the 7.3 Powerstroke. In fact-those injectors even have the same electronic connector as seen on the Navistar motors. The connector that goes to the brown plastic box looking thing is a solenoid with an electromagnet inside which, through its own complex system involving cups, pistons, valves, etc. provides very high injection psi. very advanced for its day. And that burnt injector with the jacked up O-ring probably has a bad injector cup. Basically the mating surface. Once that goes, it starts eating the O-rings.

The top end of this thing reminds me a little of the late 90s International DT466, especially with the HEUIs and valve bridges. The issue with the darkened injector is that the copper washer around the base of the injector nozzle wasn’t sealing to the head. Common if the injector was replaced and not properly tightened down or the bore it sits in is dirty. It’ll leak compression past the copper washer and burn the o-rings on the injector. The 7.3 and DT466 use very similar injectors and had the same issue. When I first started working on diesels (coming from gas engines), I complained about how tight all the bolts were and how heavy everything was. What I realized is that I was using basically tools for cars on big trucks. Trucks, and the big diesels inside them, require different tools. If you use the right tools (including lifting tools) then its not an issue.

I was introduced to mechanics at 19 or 20 (back in the '70s) when they brought me to a shop with two disassembled Cummins inline 6 engines. One came from a belly-loading earth mover donated to the school I attended. The other was a truck engine the school bought used. These engines had three heads each (two cylinders per head). They had someone with experience come in intermittently to show me what to do. With parts from two engines, plus a handful of new parts (rings, bearings, one piston, etc.) I got it reassembled. The heads had to be torqued in steps up to 480 foot pounds. I had to use a pipe as a cheater to get the last steps done. I missed some parts in the head gaskets and had to remove and reassemble twice, meaning I went through the torquing and timing process three times. The last time, the engine was in the earth mover. I had to park a flatbed truck next to the earth mover and use the bed as a platform. When all was done, it ran, but it was tight.

Cool engine teardown! I know there are higher torqued items, but the highest one I've run across was on a B-52 landing gear trunnion cap bolt. We had a special torque wrench that was made of extensions of two foot or so increments that could connect up to almost twelve feet long. The wrench went 2000 lbft. I don't remember the exact torque, but it used most of that wrench

Either cylinder 4 had a well used replacement injector or a bad injector cup, looks like combustion gasses were getting out between the injector and the cup torching the seal. I'm going to guess that the wear in the bores is from excessive idle time followed by brisk acceleration, used to see it a fair bit in bus engines rebuilt by the company I drove for. If you intend to do more teardowns of larger engines it might be worth investing in a 1" drive socket set, head bolts on bigger stuff than this can be torqued to 400+ ft'lbs.

I'm doing an inframe on a Cummins 8.3 6CTA. Not sure why I'm watching you teardown a CAT 3136, but I'm loving it. Surprisingly, or not, I'm learning a lot about diesel engines by watching videos of medium duty engine repairs/teardowns, regards the make of the engine. For those exhaust bolts holes down tabs, I use a pair of 12" Knipex to pretty them up. Goes a lot faster than using a hammer and screwdriver. Injectors can be tough to get out without an injector puller. I used my Knipex again, freeze off, and a ton of force with my indexing pretty bar and Knipex. I trashed mine, but was planning on replacing anyway as they were the wrong ones. I used my giant breaker bar on the head bolts as well. They are usually over 100lbs of torque plus 90⁰. I don't know about CAT, but on Cummins heads, you have to remove them in a specific order as well to keep from warping the head. My head is well over 400lbs. Used a cherry picker to pull it out. Takes 4 guys to load it up into the back of a minivan.

Back in the 90’s there was an issue with batches of 3126 blocks. They were listed as “Soft Blocks” and had a factory service letter out that was kept secret from the public. What happened was the casting of blocks got mixed with the wrong ratio of alloys which created a softer metal than standard. They telltale issues started out with the motors blowing smoke and loss of compression. The blocks were breaking down around water jackets and cylinder walls. I had 2 of these blocks in my boat from 1996 and Cat supplied new short blocks around 250 - 300 hours of service. They have the serial numbers of bad batches somewhere on file.

Good engine, worked on a lot of them. Common in GM and Freightliner medium duty trucks, seen a few in Ford/Sterlings. Larger version of the earlier 3116 with HEUI injectors. Nice to see you tear down a commercial diesel. You would probably enjoy an Isuzu 4HK1 out of an NPR/NQR.
@williambasinger5859
@williambasinger5859 Год назад
The 3116 HEUI was only made for two years it has an engine prefix of 1WM. It was a bullet proof engine and we never saw them come into the dealership for repairs. The 3116 is a 6.9 liter engine with only two valves. The 3126 which replaced it was a 7.2 liter engine, and had three valves, two exhaust and one intake. The 3126 became the C7. Fun fact about the 3116 engine. It was designed and developed with GM and was only found in GM trucks. Caterpillar came out with the 3126 so it could sell the engine to any OEM that wanted one.

@@mattcat231 the WAX was my least liked C7 it had a lot of injector and heui pump failures. When either one fails you will get a lot of metal contamination in the heui oil gallery in the head that is a pain to get clean. Change the oil like religion and use only cat filters is the only recommendation I have to give you to avoid these failures.

I can't imagine it'd be *too* hard for him to find a screaming jimmy rusting away in a junkyard like he did that 300. Or, hell, he could just poke his Cali contacts, since Commiefornia is going full retard and banning all older commercial truck engines outright. IE it's going to be, if it hasn't already become, illegal to run one of these engines in a commercial truck registered out of Cali. Should be a flood of tired old Detroit 2-strokes, and even some 60 Series 4-strokes, flooding out of Cali as the trucks they're in get scrapped over that law. If Eric does get his hands on a Detroit 2-stroke, I want to see him start it in the shop first.

Surprised to see one condemned over something as "minor" as fueling issues and cylinder damage. Haven't watched far enough yet to see the carnage though. These engines are very serviceable and haven't been manufactured for a while, so owners generally try to keep them alive even going as far as a deep rebuild.

No sleeves built in to the 3126, and only $11k for a drop-in-ready replacement. Diesel folks tend not to wanna bore, they'd rather pull a sleeve and replace it, which is why that was probably a "throw away" engine with the scratches. You can get sleeves that'll drop your displacement slightly, but it's got thrust plates and a non-trivial amount of machining. (not a diesel guy, just got a gloss from a friend)
@williambasinger5859
@williambasinger5859 Год назад
The sleeves that can be installed keep the engine stock as far a displacement goes, yes it is a fair amount of work to have the machine work done. 500 or so for a sleeve is cheaper than a new block, even doing all six is cheaper than a new block.
