Hi there,
I am in the process of refurbishing my "very early" A/C system, and I thought I'd document my adventure and what I learned in this thread.
The current state of my system is:
- Completely original
- The OEM Sankyo SD510 compressor engages when manually tripped
- The refrigerant is R12
- The system seems tight and is holding refrigerant, but the amount is unknown
At one point, it cooled briefly, but then stopped cooling and the compressor is not building pressure. After some troubleshooting, I suspect a blockage, but it could also be a compressor failure. I have a primary plan and back up plan to get the system operating again.
My Primary goal is to:
Refurbish my original compressor
Maintain the early style accumulator configuration
Keep the system on R12
Add the high pressure switch and pressure release valve that is missing on my system
And if that doesn't work out, my back up plan is to:
Replace the compressor
Convert to the later style accumulator
Convert to R134a
Here are some pictures:

My first step is to pull vacuum on the system before dismantling it to double check for a small leak...
