Replace air conditioner compressor
Hello,
I have a 1987 F-150, 502 V8 with an aftermarket airconditioner. I bought the truck off the lot in 1987 and had the Ford dealer install air conditioning at the dealer. I have had to recharge the system over the years intermittently but the last few years, I've had to recharge almost every year. I'm looking into replacing the compressor because the last time i recharged it, the shop told me that the compressor had a leak.
Is it possible to repair a leak or do I have to replace the entire compressor? Is replacing it a difficult job? I was told last year that the compressor would cost around $300, I figure it would cost another $200 for labor at the shop.
Any input is much appreciated.

If your compressor is leaking from the shaft seal (likely, can tell from greasy buildup behind the pulley) then you can replace it, but if you have never done it before, it is better to buy a rebuilt with a warranty. It is not difficult at all to replace the compressor yourself and save some labor.

Any suggestions as to where to get instructions on how to replace it? I'm not very well versed in AC.
I have a Chilton manual but the AC is after market and may not be the same as the standard ford components.

Really don't need a manual. As follows:
-Ensure the system is empty of freon (whether by natural leakage or shop evacuation).
-Remove belt. Disconnect hoses. Unbolt the compressor brackets from the engine and remove the whole assembly from the truck.
-The majority of compressors don't come with oil. You can add it yourself now to the new comp. (purchase separately) or let the AC shop do it when they recharge.
-Transfer the brackets from the old comp. to the new one. Install on engine. Using new orings, install hoses on the comp. Install belt and tighten.
Now the shop can evacuate and recharge. You should, while the system is open, replace the drier and any orings while depressurized.
