When I torque my PP bolts to 22lbs, there is a gap between the pressure plate and flywheel. I tried all the way up to 30lbs but there is still a very small gap. I'm worried this gap will cause vibrations (it did before).Someone said a Spec Rep said up to 35lbs is safe, anyone want to confirm?

How much can you torque LT1 PP bolts before it will cause disengagement issues?

BALLSS

The factory specs are pretty specific at 22 ft lbs. Not 23 or 24 or 35 ft lbs. I do know from direct experience more will cause disengagement issues.

If you are using stock PP bolts there should be no issue with drawing down the PP flush. Chase the threads of the FW to confirm no lock tite, etc. has built up making TQ readings in error and not allowing the PP bolts to seat correctly.

If you want to try 35 ft lbs go ahead....it is quite a bit of work though to reverse that. FWIW when I did run a SPEC 2+ I TQ @ 22

I also asume you have the disc in right...not backwards...

I'm using longer than stock PP bolts, does that affect the torque setting?

Weird. Direct from the Powergrip installation instructions on Ram's Website:

"Torque 5/16" bolts to 25 ft/lbs, 3/8 bolts to 35 ft/lbs, going around two times in a star pattern.

you need to be using stock PP bolts. the longer ones may be the issue witj the PP not seating right.

McLeod does make a set...$50+ since OEM ones are not available

you need to use the bolt that looks EXACTLT like the pic

There shouldn't be a gap.

OP, you gonna respond to this?

Maybe. If the o.d. of the smooth shank is correct, then the length of it can be slightly short. The threads can be somewhat longer, as long as the holes in the FW go through.

The disc isn't backwards - the gap would be a lot bigger then.

The bolts I'm using look identical to the stock bolts, except they have more threads.

Here's what I was able to find:


VS Stock:

BALLSS

hard to tell by the pics but it looks like the non threaded part of the bolt you are using is "slightly" longer than stock and not allowing the PP to set all the way down.

also to clarify some comments about the PP should sit flush with FW by just placing it over disc. Not true. the PP needs to compress to add tension to diaphram fingers on install. You draw the PP down by tightening the PP bolts in a star pattern and then final TQ to 22 ft lbs. It helps to chase the threads of FW to remove any old lock-tite and debris which will effect TQ process if you don't.

I am not sure who you spoke with relative to this but we recommend OE torque specs for the LT1 application. That being said there should not be a gap between the plate and the flywheel at this specification. I am happy to speak with you any time and if you can I would love to see some pics of the parts that you have, torqued as they should be, so I can better understand this gap. Thanks!

its pretty obvious you need to purchase some stock pp bolts..

I always go 22# and red loctite and have never had an issue plus I have reused my OEM bolts at least 6 times.
