Rebuilt several 12v71 off of coal haulers they were the smoothest running engine of all of the old 2 strokes when you have it down just to the bare block you should flip it over to remove and install the crank much easier
You do a hell of a good job when you work on stuff thats what it takes to be a good Owner Operator i enjoy watching your work on Orwell and the Detroit cant wait till you get it running
that crack in the water pump drive gear is from some one putting a water pump in and not getting the teeth lined up and just ramming it on with the bolts. i have never saw it before but i was warned one time about it when doing a water pump on a Detroit power unit for a old sawmill.
I like having a bunch of little cups into which I put bolts, screws and washers as they come off a project. Does look like thar engine has had a tough life. Keep at it.
Neat, gear drive with no internal chains ensures going millions of miles before it's time to open the engine up for anything short of full overhaul. I'll bet the drive gear broke first so they just parked it and the block crack happened due to no antifreeze and not draining the block. Betting on a weldable jacket only crack.
Well, that puller from your grampa sure earned it's money on this engine. And kinda funny, but everytime I hear you say them fractions, I'm like "Wut?" Still find the imperial stuff confusing, but that's probably the same to you when your not used to the other system.
Hey there shop I got it had a couple freightliners you said you were looking for something to put that V12 in when was a single bunk the other one's a double bunk if I remember I think they were like late 70s early 80s one had a 92 in it if I remember right one had a V12 and he had a whole another V12 he wanted to get rid of them reasonable I think it was 15 grand for both of them or something like that don't hold me to that but he's in the antique truck club out of Kansas City you can probably look him up that way or get a phone number or something they can go in the archives and look him up I don't remember his name or anything hopefully that'll help you but bring it cabover or well over to Springfield Illinois next year antique truck show we'd love to have you weekend after memorial Day
Seeing this engine brings back the nightmares I had working on the old 238s and screaming 318's at my first driving job. Boss loved them because they literally where next to bulletproof. Shop and drivers hated them as they where nightmares to work on and not to mention screamers going down the road.
All “V” style Detroit Diesel engines tend to be a challenge to work on as it’s just a really poor design and traditionally they’re a maintenance nightmare . I certainly wish you luck with this engine and I have no doubts you’ll get it back together. I’ll keep my fingers crossed that once it’s together you don’t go broke trying to keep it running! These were really on the way out when I started in the HD trade in 1983 (nobody ever bought one in a new truck) and quickly left the scene with the arrival of the series 60 in 1986. Now I’m feeling old…. Lol.
Woodruff keys do a wonderful job of preventing things from sliding off of a shaft.

I always thought the Silver 8V92's had a different sound than the 71's, 92's almost had a 4 stroke sound to them.

Putting that all back together should be a lot of fun. I know you can do it. But if it were me, I'd have half the parts left over (hahahaha).
Nice video Steve never have disassembled 12V71 before. Really enjoy watching you perceiver in tearing it down.
Crack? What about the missing teeth? And per your request at 15:58, Hi Stupid. Ha ha.
You feel like you been in the ring with a "Prize Fighter" after working on one like that.

STEVE..THATS WHAT HAND IMPACTS ARE FOR !!
The ol gal likes to put up a fight, but perseverance wins in the end for a better cause, keep up the top work Steve.
cheers from uk
Right on
This series is grat
try giving a light tap on the end of your puller, should pop right off.

Soon to discover if the cams are suitable for road use (Same goes for the injectors)

Hey Steve u ever found a truck to put that motor in when u finish rebuilding it?
Most mechanics refuse to work on this 12/71 these days
Very sad indeed.
are you going to put that engine in Orwell Steve?
No. A whole different truck.
I was thinking when I started watching this video remember the keys. LOL
