A belated thanks to all who replied . Anyway, I had the belt re-installed and with the A.C. operating, I have the same old noise. With the A.C., switched off, I had the same noise.
What do you think: the clutch or the compressor, or both?
My Indy. mech. has an A.C. Precision Parts rebuilt compressor, But
the O.M. plate was removed. The Part number is AS 001796. I emailed them on July 15th., quoting their part number seeking info. on the original type, but I've had no reply ( snet another message to them to-day ).
Assuming this is a perfect fit, what ought to be done before installing it - I mean specifically flushing it out, etc., and filling with mineral oil.
All you valued help appreciated.
