A/C Set Up Question - '77 Compressor Replacement

[Wendell Allen]

Hi Everyone,

The Harrison R4 A/C compressor on my '77 failed this weekend. Fortunately it didn't run long enough in that condition to throw the belt. I've purchased a rebuilt unit and am ready to install it.

My question is this: I understand I need to put 6 oz. of esther oil in the system. Some people have told me that I need to pour it directly into the compressor. Is this true? And if so, does it go in the high side, or the low side?

As always, many thanks.

Cheers!
W

It doesnt really make any difference where it is, just that it is. If you pour it into the compressor, make sure you turn it over a few times to clear it before running the compressor.
