Idler Pully - I forgot how it goes on after changing my belts! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Shaminii · 05-15-2007, 10:31 PM

So I just changed my belts on my S13 SR20DET. In the process, I forgot how the idler pulley goes back on. I have a thick washer, thin washer, the pulley itself, metal plate, and a nut. I currently have it in this order: thick washer, pulley, thin washer, metal plate, nut. Can someone tell what order they go in. My car makes horrible jiggle, scrapping noises when the car is on and it sounds like its coming from the idler pulley. The car did not make those noises before changing my belts. The belts are tight or else it would make screechy noises.

Yes, I've checked and found another thread just like this but it was never answered. So I don't want to hear any whining from the low-life "search n00b" zilvia mobsters.

Please help me out ASAP.

It is said in the FSM. That will tell you for sure how the crank pulley is installed. There isn't an idler pulley, I think you mean crank pulley or harmonic balancer, which is the big pull towards the bottom of the engine that gives you timing marks?

Stop immediately driving on it because you can destroy your pulley, cause oil leaks in the upper pan, etc etc etc....

No worries, I haven't driven the car yet. I don't think I was specific enough about this pulley. Its one the pulleys you loosen tension on to put the belt on for the AC. I've checked the FSM and it doesn't mention how it goes on unless I haven't looked hard enough. In the belt section of the FSM, they call it a idler pulley.

NVM, found on HA-70 of the FSM. Looks like the order should be: thick washer, pulley, thin washer, metal plate, nut. Hmm...maybe I put he metal plate on backwards.
