Didnt any directions come with the recharge setup?
You drain all the oil you can out of the compressor... but I wouldnt bother.
1. The compressor has been exposed to air for 2 years. It is prolly 18
years old. The shaft seal is suspect at the least.
- get a rebuilt, it will come with no oil.
2. DEFINITELY change the accumulator... I doubt it has a receiver /dryer
unless it's not a domestic.
Change ALL the o-rings and check the lands and receivers closely... it they
are pitted, you are going to have leaks and, no, they wont clean up.
I would ALSO change the orifice
Dont have to tell you to NOT use PAG, do I?
I don't know.... I'm impressed with the proper technique observed so far...
but he's worried about not pulling a vacuum from both the high and low side
If you pull a good vacuum on the low side only, it'll be pulled in the
I can't believe somebody would put gunk in the high side port like that...
unless they had already changed the valve a few times and got tired of it
continuing to leak. In any case, I doubt you'll be able to dig it out enough
to keep some from going in the system once you remove the valve.
Of course.. If you are flushing....
