Several days ago I was asked about removing the clutch assembly and I did not
have available, the correct size of the bolt I use to remove it. It is cad
plated, 5/8, x 11 coarse thread. Threaded portion is 1 3/4" long with a non
threaded portion of about 3/4". So total shaft is about 2 1/2 inches long.
Could be a little shorter so it will clear the fan and shroud if you need it
to be shorter. The hex head of this one is 15/16th.
I got it at a Pep Boys so it is easy to find. This is installed inside the
center of the clutch assembly after the small bolt is removed from the same
hole. Its threads are further inside and are in the crankshaft. This larger
bold grips the cluth itself and pushed against the crankshaft. This is the
same on all the cars I have from 59 thru the late 80's and are the V2
compressors. I do not know anything about the rotary compressors. Joe

here in Palm Desert.
