1993 A/C Compressor
Can anyone offer any feedback on a rebuilt versus a new A/C compressor for my 1993 F150? I have to replace it and am wondering whether or not it would be wise to invest the extra money and get the new one. Any thoughts on converting to 134A would also be appreciated. Thanks.

Hey GWall...its a money thing....lol..its not just the compresser, but the clean out/flush of the system[the sludge in the lines, accumulater, orfice, evap. and the leaky condenser is worse than oil sludge!] the needed new receiver/drier/ new 5$ orfice...its all about the labor....r134 is the only way to go if not a restoration..you will need the ability to discharge the system soon for other repairs and the r134 is much more user friendly....this can easy cost triple the cost of the compresser...but i sure love being cold after a day in the sun!

There is nothing wrong with recon compressors, the only problem is recon compressors that come from lousy companies, who are they?...I don't know.
When you buy a recon or new you need special tools to remove the old clutch and pulley, recons don't come with these installed. There is a special 3 pronged wrench that holds the clutch while removing the shaft nut, there are special pullers for the pulley, and when setting up the air gap between the clutch discs, you may need special washers if your air gap isn't right.
The system does need to be flushed, this could be done at home if you have a compressor and some flushing agent. The accumulator should be replaced, the orifice tube needs changing, you need to replace all o-rings in the system, which means you need the special spring-lock AC line disconnect tool. If the evaporator or condensor are leaking then they are expensive, and it is hard for the home tech to find leaks in those. I suggest getting a set of manifold gauges also, they cost about 60 to 70 bucks and are great for filling the system. You definetly want R134a, and I suggest letting a pro do it, if you plan on keeping the truck. DO NOT GO to a FORD dealer.
TRy your local, cheaper mechanic. I have heard of R134a retrofits for less than 400 bucks./
Your minimum costs, refrigerant 20 bucks
compressor 150?
orifice tube 20 to 50
new fittings and o-rings 10 bucks
accumulator 100 bucks
tools ??can be loaned at autozone . etc.
manifold gauges 60 bucks
Vacuum pump to test system for leaks and create mandatory vacuum for refrigerant to load into system...200 bucks
Possible damage to entire AC system could set you back 1000 bucks, if you screw it up. Be careful, know exactly what failed before you start, learn AC basics, and try and retrieve the r12 if there is any cold air in the system.
