Kevin,
I doubt that the water pump pulley will have enough power available to drive
the compressor. Try to set up a second pulley on the crankshaft, in line
with the water pump pulley so that the belt can go around both the water
pump and crank pulley. You will also need a way to tension the belt, so an
idler may be necessary.
If you can make the compressor and alternator fit on the passengers' side of
the engine, you may be able to drive the alternator and compressor with the
same belt.
Peace,
Pat

Gary, Robert, and Pat - you are right the compressor needs to go on the
passenger side, and fortunately my alternator is on the drivers side and I
have an extra groove on my water pump pulley. Alvin, I don't know how to
find this information in 311s.org.
That being said I believe a Sanden 508 v-groove compressor (under $150) is
what I need and a Vintage Air Mark IV Under dash (cost just under $300); as
well as a filter and condenser which I believe cost a hundred or so and come
in many sizes and can be mounted without much trouble. I'm not sure how to
mount the compressor to the engine.
Any ideas how to design a bracket to attach this compressor to the passenger
side of a U20? Anyone have a picture of the original smog pump mounted on
the passenger side?
Thanks again -
Kevin
Upland, CA
