Hi All,

I was wondering what the specs are for the T27 (torx head) fasteners used throughout the XB bikes. I think they're 1/4 diameter with 20 thread pitch, but when I use that size die to clean the threads, it seems to shave off a bit of the threads too.

Thanks in advance,
Paul in MI

the parts manual lists various lengths of pan head torx screws as 1/4-20. The socket head torx look like 10-24, with one oddball trusshead torx being 3/8-16. Just a cursory look, which specific one are you trying to fix?
Maybe I can narrow it down.

And when you find out what size you need, replace them with allen head fasteners...

But don't throw the old ones away, those little things are expensive.

Chainsaw,

It's the bolts holding the airbox down. There are 4 of them. The factory put on so much loctite that I have to put each fastener back into the hole it came from or the fastener binds when tightening. I've been trying to get the old loctite off with tap & die, but the die seems to be eating away too much thread.

Thanks again,
Paul in MI

Will carb and choke cleaner work on loctite?

Don't know a thing about it, but I found this puppy!

BESTCHEM Debonder Description: Specially designed fluid for removing Loctite and other adhesives, thread-locking compound.

A bit of heat will break down loctite eg hot air gun, oven, needs to be a fair bit hotter than boiling water, the loctite will go soft.

I thought I was stripping the threads. I will remove the Loctite.

Ha! I am smarter than all of you. I went ahead and stripped the threads! Just to make a point!

Okay, I didn't know what I was doing and it took a friend and an easy out to put me back in business.

I now know the difference between red and blue loctite. I wish the dealership knew the difference too.

Actually I did not strip the threads rather I stripped the head.

Still embarassing.

They loctited EVERYTHING on the bike. I ordered some new bolts for the airbox and they came pre-covered in loctite (and cost a lot too!).

I bought a new die and will try to clean up the mess on the old bolts. I'm sure they're 1/4", 20 thread pitch because that's what it says on the packaging for the new bolts. Hopefully, I won't be taking off so much metal this time.

I've finally discovered that the Craftsman dies I've been using are slightly off. They're cutting off ~0.02" of fastener diameter. What bugs me is the 20-year-old-cheap-ass die set at work is accurate, but the relatively expensive Craftsman stuff is off. Spiderman, I'm coming back for more bolts!

As an aside, I was wondering what would happen if you stripped the threads on the frame over the gas tank. Is there enough metal on the frame to allow a heli-coil?
