Head stud torque into cylinder?

Recommended Posts

A couple of head studs were loose in the cylinder of my '01 CR250 engine. I've used two nuts locked together to tightened each stud into the cylinder, but I couldn't find a specific torque spec in the manual. Anybody know how tight they should be?

my manual says its 20 ft lbs for the cyl head bolts... :excuseme:
Yeah, that's the torque for the nut on the stud. Do you use the same torque for installing the stud in the cylinder :bonk: ?

for putting the stud in the cylinder i usually just tighten it as tight as i can get it. BUT, make sure you use a somewhat SHORT wrench to tighten it. if you get too long of one, you will have too much torque, and you could break it. ive done it 3 time, and all bikes have been percect :excuseme:

if you have the factory service manual,look on page 7-2 in the cyl.head/cyl/piston section. it says the stud torque is 9ft. lbs.... just make sure you use a good strong locking agent, and give it plenty of time to cure...:excuseme:

Did you ever get to the point in a project where you can't see obvious things in the manual.... right under your own nose :excuseme: ??

How do you tighten a head stud?

the easiest way is to install 2 nuts, lock them together, then use those nuts to torque the stud in. they also make stud installation and removal tools, but they are kinda pricey...
