Exclamation I need torque specs for a 96 6.5

:shrug: i have searched, honest, and i just cant find it here on this site. If anyone else knows where i may have overlooked it, please feel free to throw the book at me.

:RTFM:

If anyone has this info (all torque specs for the engine, we are doing a complete rebuild) we need them! You can email me or post them here and either will be greatly appreciated!

Thanks from a newbie.

Tom

FWIW, I'd invest $20.00 in a Haynes Diesel Engine Repair Manual #10330 or the like.
No way would I attempt a total rebuild without a manual, if for nothing other than the torque specs, just not worth the risk IMO.
I'll list what I can as it pertains ONLY to the '96 6.5TD but dont assume its all correct, READ verify these numbers!

Thanks, and i will be looking for a "haynes" etc. book today while i am out getting parts.

I would REALLY like to put an "upgrade chip" on this while we have it torn down to increase pulling power in the hills.

I was told that this engine might not handle that extra torque etc.
What do you all think?
From what i have seen so far on this site, you folks do this all the time with some success. Can just simply replacing the factory chip make a noticable increase or do i have to do a mojor upgrade; new/different turbo, etc?

A short block 6.5 is no diffferent then a short block 5.7. Have the crank magnafluxed I think is what they call it for hairline cracks. I would go ahead and put a new crank in it just to be on the safe side.

:shrug: ooo, not sure, i am just doing the grunt work, i am not the mechanical expert, my brother-in-law is. I know they just got some new ones in and the piston rings were already attached for some damn reason, and they broke off, or were already broken to begin with.
They called the place they ordered them from, and the guy says "I bet your calling about the piston rings..." issed:

So i assume that problem is in the works.
