Safely Reuse Flywheel Bolts? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Simple question. I was always under the impression bolts like that were not supposed to be reused, due to being nearly torqued to yield. I think my old marine mechanics teacher preached that more than anyone I've heard. I'm replacing the clutch in my SR, and I'm wondering ,is it necessary to replace them, or are they reuseable? If I need new ones, whats the cheapest/ fastest way to get them? (if the dealer is way to expensive compared to online) A search yielded no useful information. Appreciate it guys!

The bolts for the SR flywheel aren't torque to yield. They're just torqued to 94-101 ft lbs. Torque to yield bolts are when you torque the bolts and then turn them an additional x number of degrees. Also the FSM does not say to replace them after each use.

are you removing the flywheel?
if not then dont even worry about it. changing the clutch you dont need to drop the flywheel unless you are doing pilot bearing or rear main seal.

you should always replace the pilot bearing during a clutch job.
