Seeing Wayne's (Ol2Stroker youtube channel) Pete with the 12v71 really makes the case for a Detroit in a cabover--having that extra access to the back of the engine is really nice.
I do love watching the process of disassembly and learning as you go. This is also my primary way to learn how to do things. I'm a backyard mechanic and like to dive into projects such as this. Glad we can watch as you go. Keep up the videos! Dedicated subscriber here..
Seeing that come apart reminds me of how amazing it was in the first place to design the thing. Yes, I know it's been an evolution of designing bigger and better engines over time, but it's still amazing.
I mean, when you consider that the same basic technical underpinnings lasted in Detroits from 1939 to *NOW* (tons of DDs still in the military, marine use and in the developing world where "emissions" doesn't translate easily) then that's seriously impressive. I'm way less impressed by new things that have surprassed DDs than I am with the fact that they stayed around so damn long!
One of my sons one day said to me while I was removing a nut with a standard wrench :why don't you get some of those fancy ratchet wrenches,it would be faster,and I answerd to him ''and take all the fun away''we both laugh.
The copper washers are because the holes go right into the housing and helps stop leaking also always look for hidden bolts or you will v rack the housing
I really enjoy working on that rebuilt with you Steve,like you ,when I work on my project,I assume things,and make mistakes,but that is all the fun of doing these project aint'it ?
Some food for thought. I know from watching Bus grease monkey garage. that cooling of the two stroke diesel is one factor you should keep in mind when buying a chassis and cab. is the size of radiator you can use. I have seen cab over freightliner that have a very large radiator space for the v block for Detroit engines. FWD also has a large opening. I'm not sure about Kenworth but I think they would or did. I would look for a Kenworth arrow dine I have always loved the look of them you have the best of both a conventual and the cab over.
Im not a mechanic but if the timing has to be changed from the back of the engine then sounds like to me it would be best in a cabover than a conventional. Just an observation on my part
I think International and Ford did big radiator options as well. Perhaps they all did as they all had a Detroit option. In road use I think that the 12V71s were usually superseded by 8V92TA rather than by 12V92TA.
if i remember right at one point you talked about the blower gear drive and the fact that if you convert this to a 12-V71TA turbo the gear drive is going to be different. the blower's on a turbo motor runs at a different speed. you may want to start looking now for the gear drive.
Hey Steve does Orwell hurt your back when you are driving down the road I have relatives that drive over the road and they say doesn't matter what cabover semi you have they hurt your back

Those empty accessory drive spaces on the back of the engine were typically used for mounting a gear driven air compressor and alternator.
We used 6V53s on the 44 MLB (USCG). Those Jimmy's scream, and leak ... good luck with the rebuild.
I enjoy your video no matter they are for Trucking, Shop or Train, please keep them coming!!!!!!!!!!!!!

Thanks, may be looking back some day.
Incredible piece of engineering of the time!
cool to see how these come apart. knew these wee beasties have a ton of parts but always amazed to see them all come apart
Enjoy your teardown of your 12V71 engine. Thank for the video Steve.
Fascinating, what a superb piece of engineering. There is something satisfying tearing down an engine. Good luck with the block.

Great video, learning a lot about this engine
I really enjoy working on that rebuilt with you Steve,like you ,when I work on my project,I assume things,and make mistakes,but that is all the fun of doing these project aint'it ?
Hope the block is OK and can be stitch repaired.

Once the timing is set there's no need to change it

that old Yellow Pete would be a sweet truck to get on the channel. I think you need to put this engine in an old school KW conventional or Peterbilt.

you may want to start looking now for the gear drive.
That area of the engine is called the accessory drive.
You have a cordless impact? Milwaukee? Man they sure are nice and handy. Not so heavy and having a hose to deal with too.
i hope a machine shop can fix the crack in the engine block, it would be a waste if they can't 😥
Little JB Weld will fix that crack.
The 6.4 international the one that come on fords f250 the cam gear is on back.😮💨😤
So does that make the Detroit Diesel the Ferrari of diesel engines? :-D
Well it can leak oil like an old Italian supercar so... Checks out! 👍
This is good job
Please sir Can you send me documents of maintenance of 12V71
If the block is cracked, would Lock n Stitch or a similar procedure be an option?
That hidden bolt. Sneaky devils they are.
Vent tube and that's a filter of sorts
QUESTION STEVE..WHY DO YOU USE THE OPEN END WRENCH VS THE BOX END ?? ASKING FOR A FRIEND !
Hey Steve does Orwell hurt your back when you are driving down the road I have relatives that drive over the road and they say doesn't matter what cabover semi you have they hurt your back
I really enjoyed the 12v71series but, I have a question. If you are a Cat guy, why not just use aCat? Why Detroit?
Talks too much
