Default 1984 Pully Stuck

Driving back from a cruise and serp belt started squealing. Pop hood and one of the pullys isn't moving, causing the belt to smell, squeak and create shavings everywhere.

Belt was replaced with alternator about 6-7 months ago. Coats belt.

I got a picture with the pully im referring to circled in red. Is it supposed to turn? Because it's locked up. And which pully is it?

You need a new belt tensioner pulley. It's a fairly cheap and easy fix. ABout 20.00 bucks.

Belt tensioner pulley, it is unlikely you will get it separately. Belt tensioner is what you want.

Good. That's the first thing I thought, but I'm not a mechanic.

So they just freeze up over time?

Yep, The bearing goes out in them and they lock up.

sad thing is its hard to find a replacement METAL pulley with a recessed suface now adays you get a metal pulley with a rolled edge or plastic.

Just called advance auto,

Guy I spoke with says they have a:
tensioner pulley
idler pully

(i thought they were the same thing, but he says they are different, or list different)

He says they dont have entire tensioner assembly.

Do I just need the tensioner pulley?

So I know how to change the serp belt (half inch breaker or torque wrench) easy peasy.

But I went and bought the pully, and Im wondering if its easier to remove the nut on the back of the pully itself or to remove the nut on the tensioner assembly and then remove the pully nut.

The reason I ask is Im having trouble reaching the pully nut whether its in the normal position or pushed down to relieve tension. I can kind of reach it with a wrench, but can't reach it at all with a socket.

Here's a picture illustrating kind of what I mean.

just remove the Ten, replace pulley, then reinstall. Just make sure you are removing the whole ten, not just the spring loaded arm.



Pic for reference.

Anti seize the threads , once you break the torque it'll come off with fingers next time.

Got it replaced. Thanks guys. I ended up just taking the pulley off. Just realized I misspelled pulley this whole thread. Oh well.

It kind of strained my back having to lift up on the tensioner with one arm, while crooked over and using a wrench with the other. But it took me like 10 minutes, so if I can do it anyone can.

Btw, there isn's a specific torque I should have tightened the pulley bolt to? I just tightened it until I couldn't hand tighten it any further.

Seems fine..
