leaky AC compressor

[Eric Perplies]

As Don mentioned there is no other solution than replace the seal or
the compressor. I have had a leaking seal also. I wondered what
caused the leaking seal. I decided to carefully inspect the
compressor. I found that the sheaves on the compressor were out of
alignment with respect to the engine output pulley. Because the
compressor mount was SO massive I looked elsewhere to find what was
wrong. It turned out that the big hinge joint that the compressor
pivots on has worn the frame of the mount. I had a new pin made and
the frame re-bored.

The point is: Inspect the alignment of the two sets of sheaves. A
long straight piece of metal should be all you need.

I choose to replace the whole compressor, clutch and sheaves. I found
a great price on this item from http://www.ryderfleetproducts.com I think
it was about $225. Only a few times the price of just a seal. If you
are going to go this route buy the compressor yourself. A
refrigeration supply house or a shop will likely charge many times
this cost.

Note too that the suction and pressure fittings on your freon
compressor likely has shutoff valves built into them. If you can shut
both the valves off you can likely keep the freon in your system from
leaking out. One of my valves were frozen. You may be luckier.

Good luck,
