Converting AC systems to R 134 (was: Road to Labrador)

["Dick Benjamin" <DickB@xxxxxxxxx>]

Of course, the reason you are converting to R134 is very likely the fact
that your old system has leaked out its R12, so you know there IS a leak,
somewhere.

I agree that reusing the old hoses and seals works fine, but inspect the
hoses first to see if there is any sign of leakage (an oily residue, usually
near a fitting is the usual sign), and inspect the compressor shaft seal
also.  These only cost a few dollars, and anyone with the proper puller can
inspect and replace it, and you don't need to "rebuild the compressor"
unless it is making rude noises.   If all of these look OK, then go ahead
and re-use them.
