2500HD flexplate change ?

[Bunky]

I need to change the flex plate on My 2001 2500HD

 

Is there a heavy duty plate to replace the original ? I hear of others replacing them and they cracking again ...

 

Also does anyone know the Bolt size and thread of the bell housing bolts, I want to try and put some long studs in and slide my transmission back without removing it I use to do this years ago on a old blazer I had .....

i don't think the trans has bolts in the bellhouseing...i think when the dealer pulled mine they said something about the bellhouseing was riveted on? idk maybe i'm going crazy

ya your out to lunch crustyworm

 

to the op ,DO NOT try and cut any corners and use studs ,that is a BS way of doing things ,

 

you did not mention but i think you have a dirtymax and Allison setup...

 

just remove the tranny or have someone do it that knows what they are doing,,the torque on the flywheel bolts is significant ,a flywheel holder is required in the starter mount hole so keeping the tranny near the area is absolutely not on ,it just wont work

I have a 6.0 litre in my 2500HD and I'm not sure what the difference is in this and Small block, but I guess I will check things out before attempting this

it is a small block !!

 

and who said the flywheel is cracked ???

 

i never replaced 1 at the dealer and i was the tranny guy !!

Flexplate cracking at the bolts to the crank is a very common problem.

Search here and be amazed !
