Default Loctite on pressure plate bolts?

https://honda-tech.com/zerothread?id=374522

I found out why I couldn't get into gear in my H22. Turned out that one of the bolts holding the pressure plate actually backed out and banged around in the tranny, hence the rattling noise that developed. I found out after having to pull the tranny, which is a POS in itself. Also, I found out that 3 other bolts were loose, which I can turn by hand.

So my question is, should I use loctite on these bolts? I'm lucky the bolt didn't fall between the clutch disc and flywheel...but my pressure plate cover took quite a beating! I'll take pics and show you the damage that one bolt can do.

Yes, use Loc-tite and proper torque spec. on said bolts to prevent what you described.

Might go ahead and just replace them. They have been stretched, and will tend to give you false torque readings, in one way are another...

"I" would go with the "red" in this case, then use laquoer(sp) thinner to remove them. If they gave me any trouble getting them out....

Thanx! I only asked because the manual didn't mention anything about using loctite or other adhesive on these bolts. Well, I'd rather be safe and have to go through the process of dropping my tranny again!

I'd stay away from Loctite* RED.

You'll never get those bolts off again without a torch.

Just torque them to the proper specs.

I have never had to use Loctite on those bolts and I have rebuilt and replaced my race motors over 30 times in the last ten years. I have always just used a torque wrench and made sure the threads were lubed before tightening them up.

Don't use Loctite.

...in fact, most companies who sell aftermarket flywheels print in nice big bold letters, "DO NOT USE LOCTITE ON FLYWHEEL BOLTS". Heh... Use proper torque specs on these bolts. Torque them down, loosen and then re-torque.

We're talking pressure plate bolts, not flywheel bolts. Pressure plate bolts require a lot less torque than flywheel bolts. I can't see any reason not to use loctite and you do not need a torch to break them loose. It's not like it is JB Weld, just a product to stop the bolt from vibrating out in a low torque situation.

If properly torqued, they aren't going to get loose.

Thanx...and yes I was talking about the pressure plate bolts. Definitely not the flywheel bolts!

The manual says 19lbs/ft. I rev out to 7500rpms almost daily. I think I'm going to use loctite.

I agree, those bolts have been known to come out despite careful attention to torque, ask bigstothel. Clutchmasters has suppied thread locker with some kits in my experience. Use Loctite.
