914World.com _ 914World Garage _ can you reuse presure plate bolts

Posted by: flmont Oct 21 2017, 12:19 PM

when I pulled the PP bolts they were not torqued very tight, nor did they have any type of lock tight on them So I am hoping I can..?? Thanks Frank

I’m pretty sure on a 4 you can but not on a 6. There was a thread 6-12 months ago.

Yes you can ,but why...cheap enough to buy,I use high-tensile capscrews done up to the correct torque no issues.
No harm in putting a little Loctite on them.

If the bolts weren't damaged by not being fully torqued, I'd reuse them. If a visual inspection reveals any damage, replace them,

I think the P.O. had kinda mocked up the clutch but didnt torque.

You're thinking of flywheel bolts.

PP bolts are just M8 bolts, and the final torque value isn't high. So go ahead, as long as they aren't damaged or otherwise compromised.

Because such a large diameter surface area of the PP mounting face the M8 bolts don't see much stress and are OK to reuse.
The /6 flywheel bolts are suppose to stretch like rod bolts, so it's recommended to replace, personally I think it's BS but for $10-15 worth of bolts I don't chance it.
