'86 Grand Marquis compressor questions

jsmitty on Sat October 20, 2007 4:48 PM User is offline

Year: 1986
Make: Merc.
Model: Grand Marquis
Engine Size: 302
Refrigerant Type: Freeze-12
Country of Origin: United States

I'm in the process of replacing a water pump in this vehicle right now & noticed the compressor pulley bearings are shot. Clutch spins smooth -- pulley has a real tight spot.

Here are a few questions:

Can the bearing be replaced in the vehicle, or do I need to empty the system & get the unit on a bench (in which case I might as well just replace the 21 yr. old unit anyway).
Can a 3-jaw puller be used or will that just create more issues?

FYI: The reason I don't want to replace the compressor is, not only does it work fine, but the wife never uses the A/C (this is her daily driver for 9 months of the year, minus the winter). The only reason I repaired it (half-assed: just hnbr o-rings, freeze-12 & 2oz. oil + 1/4oz. dye -- no flush) in the first place was for my comfort, in case my new truck had to go in for warranty issues.

You can remove the clutch, then the pulley is held on with a snap ring. The pully bearing can be changed, but you need to be very careful when knocking it out that you don't bend the mating surface for the clutch and pully. It might be better to buy a clutch assembly and change it all... You can e-mail the guys at Ackits.com for a price on a new assembly (clutch) or just the bearing..Hope this helps..

Thanks Chick. I didn't think of replacing the clutch assy..

Got a better look at it earlier, & the nut inside looks rusted bad. Could be a massive PITA!

I'll try removing the clutch tomorrow morning, & if it won't come off I'll probably leave it until spring & buy a new compressor (seeing that it will be off the road in another month or so).

Soak the nut with WD-40. If you have an impact wrench it will come off very fast.. Otherwise you have to hold the clutch from turning. You may be able to energize the clutch and let the belt hold the clutch in place. Not really hard to do....
