[200q20v] compressor clutch

[DAK]

Here's a question for you all.

Anyone replaced a compressor clutch with the compressor in place? Would 
be a do-it-yourself job if I don't have to touch the freon (which is 
still contained). If I have someone else do it, I might as well have the 
whole compressor replaced since they'd have to remove it anyway. I've 
kept my '87 5KTQ compressor going for 14 years by adding oil once and a 
while. I imagine I could get away with that on the '91, but the clutch 
bearing is really toast!

Anyone BTDT?
