cylinder stud torque

Post by wvsp612 »

Just got my replated cylinder back from Millenium. Looks great. Anyone know the proper torque for the cylinder studs? I searched on here but to no avail. I also have the cyclepedia manual, but i don't see it listed there either unless you just use the general torque values. Anyone?? :?

C'mon, someone must have sent their cylinder in to be replated and then had to reinstall the cylinder studs. A little guidance?

I don't subscribe to the Cyclepedia manual but I would think it would be in there. I know the factory manual has them listed at the beginning of each chapter plus in the individual service procedures.

Oh, BTW, you never mentioned what KDX you have. :mrgreen:

For E Series bikes the torque spec is 18ft/lbs (25 n-m) for the cylinder head nuts and cylinder nuts. Be sure to tighten in a criss-cross fashion.

OK, so the torque for the cylinder studs themselves is the same as the torque for the cylinder stud nuts? Thanks

Just wanted to be sure. I found the torque for the nuts was 18 ft-lbs, but I did not see the torque for the studs themselves. :supz:

My bad. I said E series but I meant H. And yes my manual says 18ftlb for cylinder and cylinder head nuts.

Probably about 12 ft.lbs for the studs. Do you have a book? The studs just need to be bottomed out good so they won't loosen up later. the torque from the nut will also help hold it in place.

I googled the **** out of this

Consensus seems to be you don't need to torque the studs

Dissimilar metal electrolysis will tend to make a stud 'stick' in the head

I've always just screwed 'em in till they bottom then back off a 1/4 turn.

Never worried about it too much.
