Torque specs for NST crank pulley install
 

Does anyone know what the torque specs are for the NST Crank pulley? I see that the Stillen one says to torque to 33 ft lbs and then tighten the crank bolt an additional 90 degrees. I assume the NST and Stillen are pretty much the same but is there anyone who has experience with the NST kit specifically? Thanks!

have you even tried calling NST? or the search button? or asking someone who's done it before? jeez

Use the same specs. It has nothing to do with the brand of pulley

Not to sound like a prick but that's the whole reason behind why he's asking the question I think man?

I would either use stillen a specs or find the torque specs on the factory damper nismo

Of course I have searched all around and found nothing on the tq specs for the NST kit, and the point of this thread is to ask people who have installed the NST kit to weigh in on what they torqued it to, but thanks shotgungho for your useless comment, lol. I also tried contacting NST by phone and email with no reply (no surprise there, lol). The main thing that threw me was that the tq specs on the factory pulley and the Stillen pulley are a little different. I will be installing thi kit tomorrow and if I can't find any specifics for the NST kit, I'll just use the tq specs from the Stillen pulley will be the closest in spec to the NST pulley.

ah that's why you're going to jtran, ron knows the specs, he's done it...at least on a 350. see ya there ;)

I'm interested in the tq specs too.

... And I would have had them too if someone posted them :p

Assuming it's a metal pulley (can't imagine if not being metal), then the pulley itself has nothing to do with the torque specs. It's all about the bolt (fastener).

download the fsm and look up the spec? too hard? ok well it is 33ftlbs plus 90degrees. tighten the pulley to 33ft.lbs. with a torque wrench then mark it and turn it another 90 degrees with a breaker bar.

Also if you are following the manual the bolt is non reusable and should be lubed with engine oil lightly prior to instal

Shít... I reused it... Many, MANY times... Without oil too... Lol

Nissan also claims the VVEL DC motors are non reusable too slow but they are lol. Thank you for pointing him in the right direction. As Arc said you're not looking for torque specs on the pulley rather the specs to the crank pulley bolt. The pulley is steel sleeved on the back side iirc so by tightening it using the factory specs you shouldn't smash or alter the mating surface between the crank and the pulley.

Yeah most people reuse it so i made it a sub note. You should put oil or antisieze on the reads and under the head tho.

I'm not familiar with how the crank bolt is constructed so maybe reusing it is OK but the "quarter turn more" part tells me it's not a good idea. I don't reuse "non-reusable" fasteners and will replace any fastener in a heartbeat if it looks/feels the least bit wonky. Especially on the drive train, suspension, or brakes. Fasteners are too cheap to take chances. And use the proper grade - higher grade fasteners are not necessarily better for the application.

on that note the bolt costs around 5.12 plus shipping from courtesy It is a torque to yield so technically it should not be used more than once but as I said most reuse it anyway and it works.
