the tensioner pulley on my car keeps falling off for some reason does anyone know why???

 

idler or tensioner?


falling off how?

it is bolted on thru the middle of each right?


you have pics?

 

it is the tensioner pulley...
somehow it just falls off and the belt losens

 

go the dealer and get a new bolt and nut that holds it together, you probably stripped it. If not grab some silicone or premagrey and put some of that stuff on the threads and just hand tighten it. Not too hard or you ll strip it again. I have stripped my already from playing put it on taking off game.


one more thing, that tensioner pulley has a spacer that holds it in place with a small lip, is that on there and is that washer behind in front of the bracket to space it?
if not then it is not installed properly

 

Is this the tensioner on an SC setup?

Reason I ask is, the shop that's removing my SC, says the stock tensioner pulley won't fit on the rod, like it's missing a spacer or bearing. I asked them to check with Nissan for the part, but that might add days to the repair. Do you have a picture of the spacer with the lip?

Right now, they have the SC polyurethane idler pulley installed where the stock metal tensioner pulley goes. It looks like it fits ok, I'm just worried it will melt. However, since running the belt for the accessories does generate as much heat and strain as running it on the SC, I think the polyurethane pulley should be ok. WHat do you guys think?

Thanks,

 

if your worried about the poly ones order one from ASP those are made out of metal. Ask for Lee they are $65 a piece.

 

did you lock the bolt into the slot? was it rattling bad before it went off?

 

dont know if it was rattling...
i tried the car around the block and the pulley fell off...

 

The poly pulley will be ok. I had to swap out the aluminum tensioner pulley for the poly pulley at the onset of winter due to belt slippage. I'll swap it out again when the weather warms up and stays that way.

I've mentioned before that the belt will melt first before the poly pulley will. What I originally thought was my pulley melting was actually melted bits of the belt stuck to the pulley. I scraped the melted bumps off and the pulley was back to normal.

 

Cool, I told the mechanic to leave the poly pulley in the stock belt setup. I'm having the SC removed, but the mechanic can't get the stock metal tensioner pulley to fit, so he installed the poly pulley from the SC kit instead.

 

hmmmm...was the bolt locked into the plate?

did you loose the bolt before adjusting the tension?

 

That's probably because of the oil line feed plate interfering with the tension pulley setup.

 

Geez man just take it to my shop! At least he'll get it going..

Did you fix the other issue with the power loss/clear all the codes?

 

No, he removed the SC oil return plate and reinstalled the stock one. He's using a Gatorback belt for the front accessories pulleys. Maybe it's the wrong size? Either way, the accessories don't tax the pulleys and belt as much as the SC, so the poly pulley should be fine in the stock setup.

 

i cleared all the codes already jer...
after i put the pulley back on i will take it to you shop right away... and thatns for your help..
