Regreasing Idler Pulley Bearings

Regreasing Idler Pulley Bearings

This is fairly self-explanatory, but I thought a few pictures might help to encourage anyone who might be on the fence about this.

Last week I noticed that my s/c assembly was making an excessive amount of noise, to point it was hurting my ears with the hood up. I bit the bullet and took my s/c in to a local eaton rebuild shop and had all of the bearings and seals replaced. During that time, I decided to give my idler pulleys a refreshing as well. You can replace the entire pulley and bearing for a decent price, but since I was already dropping quite a bit of cash on a s/c rebuild, I decided to do it myself. It turned out to quite easy and only took about 45 minutes.

First, remove the idler assembly and dissassemble everything. Once the spacers have been removed from the bearings, you can easily pop the bearing covers out with a small flathead screwdriver. Make sure to keep these in order since the covers to grooved and flat pulleys are different.

Next, I cleaned the old grease out with a bit of gas and a small toothbrush. There may be other ways to remove the grease, but this is an old trick that makes a quick job of the mess. Once finished, let the gas COMPLETELY evaporate in the sun. I left mine out for 30 minutes just to be sure.

The bearings should look like this once dry:

The last thing to do is repack some grease in the casings and replace the covers. I used some Valvoline synthetic grease that I had laying around. It was spec'd for wheel bearings, so it can handle extreme heat and pressure.

Just a final tip, be sure to check that all of your bolts in the idler plate are torqued down. Mine were lose at the bottom block which was causing the plate to flex inward a bit. As you can see, the top pulley began to rub against the inside of the plate and made a groove.

After the s/c rebuild and the pulley regrease, my kit is insanely quiet. I now can hear the engine over my s/c unless I'm boosting, in which I only hear a small whine. This is the best time and money I've spent on my car thus far, aside from the s/c purchase in itself.
