I am rebuilding the A/C compressors for both my vettes and a extra one while I'm at it.
I noticed that the back plates have a year date code. These back plates do not have (for lack of better words) the thermal switch as on the newer back plates.
Here is what I have on the 3 that I chose to rebuild.
B 03 3
k 9 5
A 6 9
Seems to follow the norm. Is the first one Feb 03 1963? And the others
Nov 9 1965 and the last Jan 6 1969?
Parts are getting hard to find for these now and I see that they may be replacing the front ceramic seal with a lip seal now. I got one of each in my hunt for parts along with 2 sets of rings.
I couldn't find any of my info I had that I used in the past for the specs on the ring gap but came up with what they actually are with new rings in a un- worn cylinder. .008 on all of the new rings. Interesting enough the old rings were not worn enough to replace at .010, about what it would take to break in.
whats the verdict on the dates?
