Part 2! Caterpillar 3126 7.2L Turbo Diesel Short Block Teardown! My Poor Engine Stand...

- 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...
Last week I started the teardown process on the first medium duty engine I've had on the channel. A Caterpillar 3126 7.2L Turbodiesel inline 6. If you haven't seen that video, watch it here first:
• A CAT DIESEL!? Caterpi...
This was an engine I found on Facebook marketplace with a suspected fueling issue and two "Bad looking" cylinders. In part one, we dismantled the top of the engine removing the fuel system, valve train and cylinder head as well as the turbo, exhaust manifold and some other parts. We found some issues for sure, but was it enough to condemn the engine?
Before I started this teardown series, I watched a few videos on this engine on another channel that were EXTREMELY helpful in both the teardown process and learning what to look for. That channel is @AdeptApe and is loaded with awesome CAT content.
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, I can't promise any more engines of this nature on the channel but it was great to step outside of my comfort zone. Really enjoyed working on this engine as it was designed to be serviced!
As always, I love all of the comments, feedback and even the criticism.
Catch you all on the next one!

The reason most heavier duty diesel engines run a 2 piece piston is 2 fold. The steel top is for heat dissipation and the aluminum skirting is to keep the rotating mass down. Plus if you break a skirt and the block and top is fine you can replace the skirt rings and bearings on the engine and go right back to work. The rods and main bearings are actually considered routine maintenance items and are replaced on a regular basis. That wear sleeve on the main seal is replaced every time you do the main seal on a Cat engine. The bellhousing adapter is to allow it to mate to whatever it is going into they have multiple types for whatever it will be used in. Trucks dozers mine trucks rollers all take a different style.
Thank you for explaining, Harold.
That is overall a great description. I just have one minor difference in opinion. The steel part of the piston is for heat tolerance during combustion. The aluminum is for heat dissipation and lower reciprocating mass. Rotating mass is actually good in low rpm high torque applications.
You're close, it has to do with heat, but not dissipation. Aluminum is a much better heat conductor than steel, by a factor of 3 or more.
Steel has a higher strength than aluminum, especially at modern diesel combustion temperatures, and it has a lower thermal expansion than aluminum, by a factor of 2. So a steel piston top is better because it is better able to withstand the combustion pressure and temperature, while it can get away with smaller piston-to-bore clearance (block and pistons have similar thermal expansion coefficients, if both are steel) which helps lowering emissions.
But the skirt doesn't need to transfer much force, it doesn't need as tight clearances as the top and it doesn't get as hot. Steel has about a 3 times higher density, so it makes perfect sense to switch to aluminum for the skirt, it saves on important _reciprocating_ mass (not rotating mass, that's the crank and cam shaft).
@@Hydrazine1000 You're close Alum shirt just guild really. Also most of Diesel engines use full steel piston now since EGR come out in 03 in truck side.
Adding to the pile..😄
Steel top piston replaces keystone rings in aluminum piston. Steel is much longer lasting support for ring sets.
Thank you for the shout out! Really enjoyed the content, you need to do a C15 next. Just the Cam weighs 90 pounds without the Cam gear.
90lbs, yiiiikesss
C15, C-15, or C-15 ACERT? Lol
0:23 This sequence was genius. Plus, everyone watching this has had this conversation with themselves about 3 times per project. Awesome content, Eric!
So true! lol
Absolutely true , every time lol😂
I was waiting for a "look away OSHA" around 10:30
Yeah, that was next level editing and thinking.
New rings, new piston skirts, new bearings, hone the cylinders, replace the injector O rings... you've got a $20K engine.
If you contact him quickly you can probably buy the whole thing and do that yourself.
Some of those scratches look a bit deep to just hone out. You could take it to a machine shop and have sleeves installed.
If that’s true all the more reason to buy two LMTVs and part one out. So many good parts
Caterpillar makes good engines. We used them in cement pumps when I worked in the oil industry.
No! on the Honing 😂
This whole engine seems to be designed to be easy to work on a easy to replace components. Very cool
Cat engineers are unsurpassed in my experience; I spent a lot of time with them in Peoria and their reman facility.
thats what I was noticing as well, everything modular, simple and easy to access
That changes when it's mashed into a truck.
This is the reason I went into heavy duty. Yes the new trucks and some pieces of equipment (skid steers and excavators in my mind are the worst) can be pains, but for the most part you have lots of room
@@speed150mph I came to a similar realization, we try to repair our own tractors usually and it’s great how you just basically have an “engine section” with room on both sides, under, and above… passenger cars are a different world
Unparalleled serviceablilty. Would love to see consumer grade stuff with this level of modularity. Replaceable rear main seal mating surface blew my mind.
Same here, we got far too many folks that throw away stuff that can be fixed. It’s an ignorant world sometimes
much of the work can be done with the engine in the vehicle, which makes servicing even easier.
I'm guessing it would add substantially to the cost of a consumer grade engine to make it as serviceable as this thing is. Pretty dang impressive.
Engine designed to work and make money. Good engine.
One big communist problem there... *the EPA*
We used our 3 ton engine hoist to pull the engine out of our 830 case tractor. Theoretically supposed to be robust enough but felt sketchy AF. I had to stand on the back of the hoist to keep the hoist from tipping over and the hoist beam was bending a crazy amount. 😬. Worked though and no one died. Keep these cool vids coming Salvage Adam Sandler.
😊😊😊
Salvage Adam Sandler. Dang I like that.
lol like a year ago in one of his videos he mentioned people kept telling him he looked like Adam Sandler
"Salvage Adam Sandler"
I almost woke the neighbors!
@@RidgeR5 he’s funny too. 👍👍
I work for Caterpillar Remanufacturing Facility in Mississippi. I work in Large Engine Disassembly and get to tear down the 16 and 20 cylinder engines. Those take about 16 hours each.
Very interesting. Train Engines or are 16 and 20 cylinder big truck engines?
2 suggestions that probably aren't necessary but would seem safer to me - 1) use a jack stand or some other support at the end of the engine when you have something that long and heavy sticking out from the engine stand, and/or 2) always use upward force when breaking bolts so you're not adding strain to the stand. Overall, very cool teardown.
With a few parts, this engine is ready to go for another 300,000 miles.
I watch Adeptape myself and also KT3406E for my dose of big CAT goodness. Both channels are a wealth of information and nothing is ever the same
If you want "big Cat" stuff, find a channel with 3512 or 3516 content. Cat even makes a 3600 series industrial engine up to 16 cylinders
Deboss Garage with the 3126 in a F350 and old cab-over with a 3406 have been good viewing.
That's the two that I watch and pay attention to for Caterpillar engine information.
Eh KT3406E is a bit of a dick. Seeing him intentionally blow several perfectly serviceable 2stroke Detroits up solely for youtube views soured him in my eyes to the point I can't bring myself to click on them.
@@nealschurr2113 too much fake laughing
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.
I love big diesels. I have owned many 7.3 and 6.7 fords also 5.9 Cummins. Only once did a 5.9 fail on me. Now I am 70 and due to a total shoulder and knee, I can easily hire the work out. But that CAT of your looks great for the mileage. If possible try to due more diesels, I am not a mechanic but love the things that make motors work.
The cam, the crank, the wrist pins, piston heads, and the rods, everything about this engine is just HUGE! When compared to a gas engine, at least. Loved this teardown, and your planning montage. Great job Eric, another fantastic video!
Well gas engines can and do get that big just very rarely. As 7.6l i6s aren't common.
Wait until you year one down yourself. You will then really appreciate the size and weight of everything! I'm currently doing an inframe rebuild (wet sleeves Cummins 8.3 6CTA). Nothing is tiny. The injectors look huge until you compare them to the heavy duty engines. Those things are HUGE!
That is one honest straightforward 'Merican engine right there.
77 years old, and I watch a tear down almost every night. Really enjoy them as I only did one rebuild (when I was 16 and we used a tree to hold a block and tackle to pull the 312 out of an old ford). I've driven just about everything I wanted to an Excalibur and an XKE back in the 60s to my current ride in an Equinox with a 1.5 turbo (pig). Keep up the wonderful work you do. The Cat Diesel was amazing and I admire your guts (and good sense) when dealing with a huge 6-cyl. industrial diesel. Stay safe! PS...How about trying an electric?
“Ooh! Girthy!!!”
You forgot to say, “That’s what SHE said!” LOL
What a wonderfully engineered motor. No wonder those things last so long.
Best damn teardown channel in YT. Brought back memories of dealing with construction equipment in the Army. As seen there, they are dummy proof, lol. You bring out what's most exhausting about them... how heavy everything is. Never saw one tore down below the head and valvetrain, so thanks for that.
I'm super impressed with this engine...a straightforward design that's easily serviced, uses what appears to be good quality durable parts, and was built to a high standard. If only every engine could be so well-made, we'd all be better off for it
This is a pretty solid advertisement for that engine stand. I've got a BBC to build and have been looking for one I know can safely bear the weight.
They should make them out of wrist pins
I have this engine in my 37' RV. Only 60k on the clock. I am amazed at how easily it scoots 25k pounds along, and love listening to the sound of it doing so.
I have a Cat 3208 in mine - pre everything. The 300 HP accelerates the 19,000 pounds just fine. Now if I just had a 6 speed transmission with a retarder I would be in hog heaven. Four speed on the flat no problem but in the mountains the gears are a little too far apart.
@@johncooper4637 6 speed with retarder? im guessing allison trans.
Stinky and noisy. I'm not sure why people love em so much. Other than the ability to pull and carry excessive weight adequately.
But most people who own a diesel never even needed one. Was just to say "I have a diesel." Lol 😹
wow something that can actually be repaired!!
Its a sleeved (dry sleeve)engine along with its newer C7 stablemate cat part # 1077604. All this needs is sleeves,rings and bearings.
This was your most entertaining video of all time. You may be the world leader in engine comedy.
The planning phase montage and cuts just affirm my process as valid.
I worked for a competitor to CAT for 10 yrs. In analyzing their designs, they are always very robust on fasteners both numbers of bolts and size on any given joint. Impressive equipment.
Some high value parts in that engine.
You need to talk to Jason @fireballtool and have him make you an engine stand for your forklift. 😂
I am willing to bet that this will be one of the most profitable tear downs you've done. Here's hoping for a DD13/15/16.
I followed this through from part 1 and I have to say this was one of the best engines and teardowns I've ever seen on UA-cam !
This engine is very smartly designed and very well thought out - I would say It's a mechanic's dream to work on one of these great engines... provided it's out of the truck lol - Only Joking ! - Great engine - Awesome video as always - Keep the great teardown videos coming man 10/10
this engine should just be rebuilt. it is in very good condition
Feel free to email him and get the motor from him and do it.
Your gonna get alot of suggestions for more diesel teardown I'm sure, but you need to do a 6-71 Detroit. Designed in the 30s and used for decades. Love the screaming jimmie!
my first truck driving job was for a local steel fabricator, I drove a 1975 GMC Brigadier that had a 6V-92 Detroit. I blame it for at least some of my hearing loss lol
Disclaimer: be prepared to swim in oil.
Detroit always mark their territory!
I love that you're willing to go outside of your experience, and tear down something new and different.
Also... no matter how much you complained about how heavy some of those parts were, it sure looked like you handled them better than I would have. No way in he11 am I going to arm-wrestle you. 🙂
When I seen that piston design I almost cried.
It is beautiful!.
This reminded me of my first engine job in High School. I had to remove 1 big block 402 from my 72 Caprice Couple and only had one tree limb to use on the oak tree in the back yard so I removed both cylinder heads first so as not to break the limb.
another entertaining and informative video Eric 👍
glad your new engine stand is still in one piece :😀
Really enjoyed that teardown, a very nicely designed engine which just goes to show what engineers can do if they put their sensible hat on.
Gotta be happy to get out with no injuries, 'cause that thing was crazy heavy. Love the "outside the box" teardowns. Love the heavy machinery content
I had a 2005 Kenworth with a Cummins ISX engine. I was driving near Joplin, MO one night and heard a knock in the engine. I shut it down immediately, which ended up being my big mistake. MHC in Joplin tore down the motor and I had broken a wrist pin. I don't know if it was defective or something, but it broke in half. Shutting it down immediately saved the motor, but it was never right after that. I would have been better off if I had just jammed the pedal down and ran it until blew up. It was a company truck so I wouldn't have been out any cash. 😁
Also The two-piece piston offers several advantages. One important advantage is a lower top land height, thus decreasing the crevice volume, the volume within the room defined by the top land and the cylinder liner, hereby reducing engine emissions. Alot of people think it'd for heat reduction it,s not
Anytime you have a metal tab attached to a bolt, keep your fingers clear!! They have a tendency to stick to the bolt and basically become a blender blade when attached to a power tool.. yeah.
WOO! PART 2!
You know what else is girthy? The crankshaft from a Cummins 6BTA 5.9L marine diesel. Would love to see one of those torn down. Love the videos, Eric!
These are very service friendly designs. Common wear points can be replaced because the wear points are all sacrificial. The skirts and sleeves are replaceable during a rebuild. Also as stated in another comment, aluminum skirts keep rotating mass weight down and wear will keep things in balance better.
Going out of your comfort zone, but you sure made it look easy. It's amazing how indestructible all of those parts look - and quite serviceable (for obvious reasons, haha) too. Loved the planning sequence and thoroughly enjoyed this series.
This tear down really showed the difference between an engine that is expected to do a ton of miles / hours then be rebuilt vs a gasser that is all but disposable now.
Well your also not comparing industrial gassers of the same size.
Very nice, those Pistons just like a Cummins 8.9 but the way those roller followers are mounted is brilliant I bet the only thing wrong with it was the O-ring on that injector. I don't think the bearings were bad enough to make it knock or have low oil pressure. You got a good deal on that one.
Cummins suck! the only engine they made worth crap is a 12 valve. I'll worked on them all. working on a isx 15 now and a c15 and 3406c.
@@billybob-de8eu blame the emissions control regulation. also if you suck at your job then everything will suck.
@@mann_idonotreadreplies I don't suck at my job, Cummins suck. i t/s and repair more engines, aftertreatment systems, and electrical systems In my life time then you can imagine.
@@billybob-de8eu you’re working on trucks?
@@ThanksHero yeah. that's what I do. I just t/s a 6.0 power stroke. got a 3406c apart right now
Light polish and a hone. New seals, bearings and some cryo headbolts, some CAT yellow paint and you got an engine that will go another 500k miles easy.
Eric thanks for sharing with us! A lot of people like, and learn from your videos, and it's entertainment, thank you so much for the journeys we take every week. I wish you the best and more!
thx for the part 2.. it is a beautiful engine design. I cant see enough to call it a loss. I am pretty sure it would have caught a hone, rings, bearings, and repair that injector issue then went 1 million miles after.
Those pistons are articulated pistons Cummins and other engines use something similar. I do know that you were misinformed on the cylinders, the block dose have liners in the block which can be replaced during a rebuild. I was a diesel mechanic for 26 years and I have installed many liners both dry and wet liners, dry liners have to be chilled with dry ice before installation. The counterbore needs to be checked before installing liners. Cheers Glenn P.S.I really enjoy the teardowns.
Generally, the bigger the engine, the more modular and nicely built it will be.
On engines approx double the size of this, pretty much all wear surfaces start to be easily replaceable.
Of course you know what you're doing.
You're taking out bolts until things fall apart.
Fantastic finish Eric. Looks like a real good engine. You did great job for not knowing this CAT engine. Well done.
Someone else brought it up, so I will second the motion... Do a 6-71 2 stroke Detroit... not big on power, but have been in use since the mid 30's, and I still love the sound of them... The 71 Series engines went from a 1-71 all the way to a 16V71, and the (71) stands for Cubic Inches per Cilinder... Love the channel, and keep up the Great Work...
Even though I've watching about 30 of your videos, after this one, I finally understand what a 2-bolt and 4-bolt main is. ...yeah, I'm a bit ashamed of myself. 🤣🤣
Fantastic video, as always! Now get something really big like a C15 CAT or an ISX Cummins. Fifteen liter monster out of a motorhome or a semi. You think the head bolts on the Mercedes was bad? Crack those loose!
SKF makes replaceable wear sleeves like the one on the crank under the name "SpeediSleeve". They´re usually designed to go on a worn shaft without machining and using a standard seal.
I have a suggestion for an engine teardown: the SISU HD98 inline 7 cylinder, It is installed in Massey Ferguson combines. Thanks to you and Josh, you both have great entertaining channels
Here’s a tip for you - and I’ll use the example of when you tried to loosen the first main cap bolt - if you look at the angle you held your breaker bar at, you were putting a LOT more weight onto your engine stand while you were loosening that bolt - VS - if you’d rotated the engine with the crank facing up and then positioned your breaker bar so you were pulling ‘parallel’ to the length (your bar at a 90 deg angle to the crank) of the engine or crank. Hope this makes sense, kind of hard to explain. But the end result is to work with the physics of the whole dynamic, instead of against it. Same thing applies in many different scenarios of when you’re loosening tight fasteners.
I watch a lot of your videos. I love what you do. This video shows me your very humble. Nobody can know everything, and you even say you don't know what your doing. You still do a great job! Now, you have a beast on your belt! I don't know anything about diesels either, but you now have the experience i would have enjoyed as well. Keep up the great work.
I welded 2 gussets to my prime engine stand for big block builds, one directly under the top tube that holds the swivel mount, and another at the bottom of the main upright and welded the upright to the base…it doesn’t unbolt anymore, but it is sturdy and doesn’t flex when you rotate a complete big block anymore. Before this, it would flex enough that the paint would crinkle and end up falling off.
God bless Cat! All of their equipment is designed to be rebuilt, from the 797 all the way down to small unit assemblies like the C0.5, all designed by Cat to be completely rebuilt. LOVE EM !
A great piece of engineering and a great video, really interesting seeing something different but wondered why is was junked cheers
Overall one of the better engine's CAT ever made worked on many of them, only ever seen one seized and the driver was told drive it see if it makes it back and a piston had come apart, the blow by on one of these could be massive and they would still run. good video overall.
That engine looks quite rebuildable to me.
Yep, as you get older (past 40), the exuberance of youth starts catching up to you. ;-)
Join the club getting older I’m 69 😊
The exuberance of youth passed me a long time ago !
@@TXCherokee
Excuse me but you’re just getting started good, now the fun begins.
Thank you for being as overly careful as I would be. Thank you for the comedy relief we all need. Just let things fall and run away! I Love Your Channel!
I see 'Cat', 'Bottom End', and 'Teardown' and I click. Not what I expected, but still enjoyable.
Majority of these motors when they go bad it's the rings and sleeves that give out then you have tons of blow by or if you're really lucky a rob bearing gives out and the Piston goes through the side of the block.
This engine is well made and designed to be overhauled even after lots of hours/miles. Kudos to Cat.
3:48 Diesel engines are notorious for oil leaks in general. They tend to have very poor crankcase ventilation and is is very easy for one, especially once it's got some miles on it, to have a positive pressure inside the case.
I drove a fuel transport, 9000 gas, the oldest truck in the fleet had that engine. I had a c12, and it was like driving a go cart. Cat engines are the best, to bad they are no longer an option on big trucks anymore. There are plenty on the road, but only older trucks.
I used to drive a bobtail with a 3208 cat...that thing ran exactly the same empty or full.
I have no experience but it's easy to see why these motors last so long, everything is so heavy duty. Too bad there's always so many negative ppl commenting on these videos. I enjoyed this video a lot. Keep it up.
@ 13.08
A slight curve to the left is considered normal.
No worries.
Thanks! One of my favorite teardowns!
I think that engine would easily be rebuilt. Not sure what to do about the cylinder wear - I doubt CAT sells oversized pistons for that engine. Maybe bore it out and sleeve it?
Hey Eric, this one was really interesting. I wish gas engines were so easy to service. The parts in this thing were pretty much indestructible but easily replaceable. Very impressive. Cheers!
I think that we established that this engine uses dry sleeves. Getting the old ones out will take special equipment.
Try using 6"x6"x3' wood cribbing. When I got used to it, I barely use the engine stand. It's super stable and weight doesn't matter. Plus you set it at any height you want to eliminate back strain.
In the fall of 2022 I was considering using cribbing to jack up my semi truck so I could do some work on it.
I ended up giving up the ghost because after going up some 38 in, it would just be less expensive and less hassle and less storage space to just get jack stands.
Six-by-six cribbing probably could have done the job but then the cost is almost at what jack stands are to go up that height to reach the bottom of the frame-rail.
I guess spreadsheet out and everything it was very interesting. Watched fireman train with Caribbean on UA-cam.
But if you're only going up 12 to 15 inches or so, 4 x 4 cribbing can easily and affordably do that.
As much as everyone dislikes Harbor Freight, the engine stand stood up to the load of the CAT engine. Care was taken to remove as much weight as possible, but it still held up.
Wrist Pins are made out of the same material as the trash compactors on the Death Star.
I'd luv to have a 5 - 6L engine, constructed this robustly , but lighter and intended as a replacement engine for fullsized Light duty pickups, w/a universal bell housing.

Duplex pistons, awesome!video! Great for heat dissipation and alignment.
Loved the heavy part of the tear down. How wide, huge and indestructible parts look.
How about tearing down a B engine code 5.3L LS? I know that they are different from the z and other engine code 5.3's, but don't know exactly how they are different! Great job tearing down this engine. Really good info on it1 Keep up the good work Eric!
A great ad for Hobo Freight best engine stand. Love all your videos.
00:23 is me every weekend in the garage🤣 very familiar self-conversation
Love this channel and the very interesting diesel teardown, plus the wide variety of engines you disassemble. You have tackled a wide range of engines, even a transmission, but some day it would be fascinating to see a teardown of something at the other end of the spectrum, like an airplane engine. I know you don't have anything to do with them, but since they are usually a boxer-style layout, and you've done a Subaru, it would certainly be entertaining.
great videos Eric! I drove OTR trucks for a dozen years, with all different engines. the CAT powered ones (in my experiences) were the best in performance & reliability. the DDs were ok if they were set up right, but I never had a Cumm-apart I didn't hate for some reason or several.
Good job Eric! I feel for you I have no idea what to do with a diesel engine!
I can tell from this teardown that you enjoyed that big ol diesel. I certainly did.
Great video! So interesting to see the big stuff. A lot different from my VW Rabbit diesel, except for the wristpins. They were huge, too. OK, not as huge, but still pretty heavy compared to most gas engines.
Accessory Drive, thats where you are at 4:55 this aluminum piece, accessory drive housing, the front is the Acc dr Cover.
at 17:43 a piece of rubber hose is good for that, vacuum line fuel line what ever size fits.
Main bolts are about 180, head bolts around 320 Lbs in stages, thats what you need a Torque Multiplier for.
The outer ring at 25:41 thats a Speedi Sleeve, totally replaceable, front of the crank too maybe. 26:11 the pistons= that's why they Idle So Nice! Soother running engine last longer. CAT!!
Either it got tired or "it was just going down the hill and quit running" too much engine retarder Bent Valves everytime. Use a hammer tip the valve stem while still in the head listen for the PoP just like placing your closed hand over an open mouth or the way they pop when lapping them in. As easy as those pistons came out means not much ware, good rebuildable for another couple hundred thousand. All the other this and that, I say Rebuild It with CAT Parts. at 300,000 plus it just got tired, as easy as the pistons came out low on compression if it started especially in the Cold the mains might of even rattled too??
Good Show!!
Amazing two parter thanks Eric
Lessons through pain association. Wonderful teacher.
Excellent example of an entry level medium duty diesel that has done its job for many years. Maybe should have gone 500K miles... but a great education in what a genuine commercial grade diesel is designed for. A Cummins 6.7 Liter is in this league. Nothing else comes close.
I love your enthusiasm sir
A Primo Video Mr. I Do, Always something useful to learn from your hard work. Thanks !
Do yourself a favour, and put a short piece of rubber tubing on the connecting rod studs before pushing them out of the engine. This will prevent any scoring on the journals and cylinders.
Excellent work as always, Eric! Also, good to hear that you are becoming more aware of safety as you get older. I was the same when I was younger, and now I try to think of EVERYTHING that could go wrong!
Have a great day, Sir! And God Bless! o7
I wouldn't really worry about it on an engine thats getting rebuilt... The liners will be bored and you'd have to have no business working with tools (or engines) if you managed to do that much damage to the cylinder by bumping a rod bolt into it.
@@volvo09 Eric is the first to say that he doesn't know what he is doing. That said, he has been salvaging parts for long enough to know how to save the good stuff. And as a Mechanic of 35+ years, I want to give him tips and tricks to help him on his journey. He expressed concern, I gave an answer. He reads all the comments. And personally, I do worry about the condition of everything when I disassemble it, and when I reassemble it. It's a simple thing to do to prevent damage.
Have a great day! o7
Excellent video. Learned a lot. Would be very interesting to see you go thru a Mercedes OM606. These engines are absolute jewels but probably price prohibitive to acquire. Keep up the good work.
I was going to say you could skip your gym workout today but this was probably recorded a few days ago -- maybe even a week. I worked as a parts runner for a diesel truck shop many years ago and I saw some pistons that were much larger than those. I have no idea what they came out of but they must have been 6 inches in diameter and I'm definitely not exaggerating.
Bulldozers, I'd say. Motors that never run over 1000 rpm.
