Bad Compressor pulley bearing?

MXHOWES on Thu April 09, 2009 11:04 AM User is offline

Year: 1997
Make: Ford
Model: E-150
Engine Size: 4.6

My 97 E-150 started to make a terrible grinding noise from one of the belt pulleys. Turn on the A/C (which works perfect) and all the noise goes away, turn it off and it takes about 15 seconds for the noise to return. I believe sit should be the Compressor pulley bearing.
I did not see this part listed separately in your parts list. This is a replaceable item? Can it be replaced without removing the compressor?

Thanks,
Jim

Depends on how accessible the clutch assembly is as you will need to remove the hub and pulley assembly to replace a bearing.

Item number 1962PL $ 12.00 plus freight.

You may want to remove the belt and check the pulley, make sure the pulley is the problem. The FS10 compressor has a pressed in bearing with the edge pinched down to keep it in place. Also make sure the nose cone of the compressor is not damaged either, if it is the new bearing will only do more damage to the compressor. A New Replacement may be necessary.

Hope this helps and good luck!

Is the A/C clutch suppose to sit in 3 rubber bushings or something like that. This one is just floating around in those 3 oversized holes.

Well you could have just a bad clutch plate. Yes, it will have three rubber dampeners that help with balancing and cousins when the clutch is engaged. If the dampeners are gone, then start with a clutch hub. But also check that bearing..

If the clutch got hot enough to melt the rubber out of the damper bushings. I would pull the OT and check for debris. especially with the FS10 compressor!!! This is sounding more like a compressor going south heating up the other components to the point of failure.

Follow the good advice that is offered before buying anything. Make sure you do not have a Black Death failure, a big problem with the type of compressor that is used on your application.

Another point to think about is that if the rubber is gone, and the bearing is bad, it may have affected the coil. The more the pulley "tilts" the more it will rub on the coil until it shorts it out. I think you'll be looking for a clutch assembly minimum and probably a compressor replacement. Check out 97 E series van replacement parts.. Hope this helps..

OK, got the clutch and pulley off of the compressor. The clutch is missing the rubber holders and the pulley bearing is shot (no seals or keepers). The nose cone surface that the bearing sits on looks to be in perfect shape (no spin marks) Now, when I turn over the compressor by hand there is one sticky spot on every revolution. Before I took the pulley off the compressor sounded great (no noises) when engaged. I didn't take any gage readings before but right now it shows a full (45#) static charge.

So here are my questions........
In the black death article they talk about looking for sticky spots when you rotate the compressor which this one has but it is perfectly quiet when running. ???? good or bad?

Also, because I NEED my van this weekend I was thinking about pressing in a new bearing and putting it back together without the clutch pressure plate, this would get me back on the road and time to order all the parts I need to do the job right (and find alternate transportation). I would like to put this off because I also need to do a new radiator (which I haven't procured yet) at the same time.
See any problem with running this with a new bearing and no pressure plate?

Thanks,
Jim

No, as long as you have a good pulley, you just won't have AC.. It will work like an idler pulley, thats all..

You will have resistance in the pump and may even have a tight spot, which will be fine. Now if you have a hard to turn and feel a rough grinding in the rotation then I would say you have a problem. The only way to make sure is to remove the orifice tube and inspect it.

You can run with the plate off, be sure the snap ring is on of course though. If you need something quick you might find some usable clutch parts on a "bad" compressor at a junkyard. Keep the pulley and plate together as a set.
