Friend of a friend of a friend found me a used running jasper reman 6.5 TD complete motor. I asked him how much and he said 350.00!!! I bought it sight on seen and the only thing is the motor is mechanical 6.5 with the old pump. I think it is a 94 or 95. It is water pump to flywheel, intake to oil pan, turbo and exhaust manifolds. Could this motor be just dropped in? Is that pump better than the electronic pump that I have from the 1998 motor? THe engine number is 12552929. Is this a good number? I might just strip the motor and use just the long block with my turbo, intake and injection pump. WHat do you guys think of all of this? WHat is the significance of the casting number? Good block year?

The only problem with using the old pump is you have to change your ECM to make your tranny work without the electronic signals from the pump/engine.
Better off, taking your pump/turbo/timing cover, sensors etc and swapping them on to the other engine. By the way, I'd be very interested in purchasing that mechanical pump.

i would also be interested in that pump as you already know tdg lol!!

Conversion is possible, is it worth it? Use trans kit

You'll also need mechanical throttle linkage and a host of other odds and ends. Manual trans will need the electronic speedo conversion.
If your hard core the swap should be apiece of cake. Not for the weekend mechanic on a budget.

I am gonna do the swap of my new 98 parts to the older motor. I will have parts up for sale then. What is the deal with motor numbers then? Anyone know anything about the casting numbers 12552929? Are these good numbers for a block.

929 sounds like an old 6.2 casting. I'm notso familiar with those. You may find injector to manifold interference if the head castings are 6.2 and it has the long body injectors.

All turbo diesel 6.5L motors take the same injector. Should fit fine.

what's the difference to the 6.2's

6.2s use a long body injector, 82 6.2s use long body coarse thread.
Long body fine thread 6.2s and ALL 6.5s use the same thread.
6.2s and 6.5 N/A are set at a lower opening pressure than 6.5 Turbos.

That 929 number is a 95 model 6.5L Diesel, it can also be a 6.2, but not so common. Most 6.2 and 6.5 blocks that shared the same casting were the 599 vintage blocks. To answer the question if it's a good block, yes it's better than the later 97+ blocks because it lacks oil spray piston cooler jets.

The 929 block will not be a direct swap into a 98 chassis. Some things to ponder. This engine should be electronic, but since it's a replacement engine it could of had 92/93 model mechanical equipment installed onto it. These items would be a DB2 injection pump and lines. The hole in the timing cover where the crank position sensor been would be filled with a plug or the timing cover swapped out for the earlier one all-together.

This engine can be made to work in a 98, another thing to consider is the oil cooling line connections for a 98 will be the 5/8" thread verses the 1/2" thread connections to the block. GM sells adaptors to go both ways at the dealer, but they ain't cheap. Another alternative is to swap out the oil cooler lines and the oil cooler itself to the older style 94/95 style cooler.

Ditto, should work fine with those few mods. Most retrofit engines just blocked off the hole in the timing cover, shouldn't be an issue. Swap injection pump and lines and use a bushing to convert the oil cooler lines.:grd: for piece of mind, I would pop off the oil pan and inspect the bottom end. Look for main web cracks and check the bearings.:ro) :exactly:

Hmmm, the 599 casting was 6.5 up to 94-ish, and most 95/96 models had the 141 casting. Never saw a 929 or where it fits in.

If it has had a turbo on it then you should be OK as far as injectors, but if it is w/o manifolds, I'd check deeper.

I'd fer sure look at those bearings and replace if I had any concerns.

Kennedy,

The 929 block is the casting in between the 599 and the 141. My 6.5 in my 95 (late 95) has the original engine in it, and it's the 929, it's quite an oddball cast, at least thats what I had thought when I found the number. I haven't seen any of the 141 blocks in 95's, mainly only in 96 model trucks.

I wanted to bring this to the top. I am looking at a 94 F engine just pulled out of a truck (engine knocking bad), and it is a 929 block. I thought I would pass it along.

BTW, I can get the complete engine minus the accessories and turbo for $400.00 (so basically long block, IP, and engine harness), but with a known knock. Worth it for a builder and spare parts?

Worth it for a builder and spare parts? i would pull the pan on that motor b4 i dished out any $$ i bought a running motor with a knock when i took it apart it had a 2 piece crank in it block was scrap crank was scrap 400 is a lot to pay for some used pistons and heads :D
