Bad blower?

[toomanytoys]

I was just wondering what a bad Eaton sounds like. I have a strange chirping/squeaking coming from the front of my engine that gets faster with rpm. The noise goes away with the fan belt removed. All the pulleys spin smoothly and easily though. Any help here would be great. Thanks

Sounds like a bad or just squeaky belt. What belt are you running?

I would change the belt and change the supercharger oil. Do some cheap maintenance first.

Not sure of the belt. Has no brand on it and I never changed it. But I will start there

A small splash of water typically quiets a belt chirp. It won’t quiet a failing idler bearing though.

Sometimes flipping the belt will relieve some squeaking as well.

I did the water test and the noise didn’t stop. Tried spraying a little wd40 on the pulley bearings and that didn’t help either. That’s why I was thinking the blower

Those are sealed bearings. Lube won’t get to them.

Get a mechanics stethoscope

I have one. Didn’t think to try it though ( don’t know why) maybe I’m getting too old. I’ll give it a shot tomorrow when the rain stops. Thanks

haha I completely read over that. Guess I am use to the old days.

When I had a Gates built it chirped badly. Put on a new Gates on. It still chirped. I did the water trick and still. I replaced all the bearings in my pulleys, and still chirped. I switched to a $16 Gatorback belt and the noise has been gone ever since.

I’ll second this ^^ sometimes you can do all the tests and still have chirp. Mine went away on it’s own after driving a few times.

As others have suggested, definitely replace the belt with a new one, preferably a different brand.

I have a 4lb lower with a 3” upper and a auxiliary idler. Would the blower belt still be the same length?

 

[toomanytoys]

Oh yeah I also have a 3.1” alt pulley as well

Follow this chart to determine proper belt length.
