torque converter come apart

[blazinzuk]

Well really just the bolts. So 2 questions do I really need to run all the bolts? This is a diesel heavy duty converter so it has 6 bolts. The mating surface on the torque converter bolt holes are kind of beat up, not really flat on 2 of the 6. The others all look good. I think I can save the threads. Really dont wanna have to buy a new converter.

And yes getting a new flexplate too. It is hammered

I would run all of the bolts. It was designed that way for a reason. And balance may be an issue. As for the messed up mounting surface, pictures are needed. If it doesn't deflect the plate and the bolts torque correctly, should be ok.

I's say all 6 is best--but even 454's in motor homes only used 3 bolts on the torque converter ,so I guess its anyones guess what number is really needed..

I'd say if 3 out of six were spaced at the proper intervals like a "regular" converter it'd live...I know guys who put a tranny from a gas engined truck into a diesel and just used the three bolts and had no issues..but diesels do have higher torque and lots of vibrations,so maybe 6 is a must?..I'm sure GM used 6 for a reason..

I am not worried about the. Load but like Wade said the balance. A stock 6.2 I am pretty sure has less torque than the 350 option

You can use three, the "shake factor" is more of a concern than the engine torque, which is why yours may have gotten loose in the first place.

Thanks Greg I kind of figured that gonna try to clean up the threads and still use all 6 do you think this will be a problem

Id grind it flat...stick a washer or shim between the flexplate and tab if needed....run a tap to clean the threads and call it good...

You could do that, just be sure all pads are the same height when you are done and make sure the bolts used are not too long as to bottom out in the pad. The other side of the pad is the clutch surface so dimpling that will be a bad thing.

On 2 differnt occasions, I had one bolt come loose and another time the bracket broke for one of the bolts. Both times I swore there was a rod knocking. Crank them all down

Plan on cutting the bolts to get as much thread engagement as possible.

Gonna use loctite this time

Too bad you weren't closer Eric...I`m sure there is as few converters in our shop for that 6.2.
