loctite crown wheel bolts

PostPost by: mini64 » Mon Jun 27, 2016 11:09 am

anyone Loctite their crown wheel bolts? I found mine backing out. Questioning my torque wrench now. Would be quite a job to clean the threads before loctiting of course.

If you use the correct high tensile bolts and torque them to the specified value then you should not need it. But it cant hurt, just make sure you finish torquing the bolts quickly before the loctite sets

The bolts backing out either means they were not tightened sufficiently or that they stretched in use and became loose. They may have stretched and cracked so they should be all replaced.

I used ARP flywheel bolts for the 6 bolt crank for the diff - come in the required 6 pack from Burtons, they are slightly longer and are a suitable high tensile bolt with the low height head. You need the longer bolts if using a Quaiffe diff centre as the flange is a little thicker than the flange on the standard diff centre (this was recommended to me by someone on here). I have not checked their l length suitability if you have a standard diff centre, you would need to make sure they don't bottom out.

I've Loctited crownwheel bolts - it's just piece of mind. Some Loctite threadlock wil work even with assembly oil on them!
Longer ARP crownwheel bolts will more than likely bottom if using a standard differential carrier. They can be shortened but you'd be just as well off in fitting a good set of genuine used standard length ones. If you need some I can have a look through my spares - am willing to post to USA if it helps.
