Thx for your quick reply, Bernie.
I looked online after I wrote my email and Blau carries two different
clutches for our year. They say one is 9/16" larger than the other...
but they don't say what either actual size is, so how am I supposed
to know what to order? Sheesh...
Can the clutch be replaced without removing the compressor (and
therefore having to pay a shop to evacuate the system?) It looks
like removing the bumper and aux radiator might be preferable to
the expense of evacuation and compressor removal.
What Bentley shows for our 91's looks more like what ETKA shows for
the 92 and after 100's than the 91 200Q. Another Bentley error?
Lastly, if it is only the clutch, what's your opinion on whether
to replace the entire compressor at this age (195K) regardless if
only the clutch is actually broken? I've never heard an opinion
on this, and I don't know what life to expect (what wears out when)
in an A/C compressor unit. FWIW, I'm still running the original R12.

Sounds like you need a new AC clutch.
