hello there,my name is paul I have been to your fine establishment and purchased shaft seals twice. The compressor is a 10p15c,three times this has happened to me,I install the shaft seal so very carefully, put back on car evacuate[I can tell when it is down by shutting valve to the pump and what the gauges say]then leave it sit for an hour and no change on gauges,already added oil with comp. on the bench.Break vac.with gas[134a]start car add gas until suction press.hangs about 35 to 38 with car at 2000 rpm,s. a/c works very well for any where from 3 or4 days to 3 weeks is the longest run I have had.When I put gauges on always has high suction press.and when I remove comp.s[like I said 3 times 3 comp.s]it is like they dont pump any longer.This last time I bought the3rd comp.and it didnt pump after just installing the seal.So I tore it back down and totally cleaned up all the valve plates[seemed to have some aluminum corrosion on the valve plate] and all the valves,I used the best parts from all 3,installed vac.,charged ran about a week and right back to high suct. press lower tha normal disch. press.I have extensive ref. experience with large industrial centrifical chillers,even converting a 2500 ton machine to 134a,but I just dont get this little toyota, Your wisdom will be greatly appreciated.

Replace the compressor with a brand new 10pc15c instead of pulling parts from a bunch of other compressors and be done with it... unless this is what you enjoy doing.

Well I am truly sorry,for bothering you,but if I thought that the same thing would not happen to a brand new one I would probably buy one,but I believe that I was or am doing something wrong and thought that maybe you guys could tell me something before I went and ruined a new one.BUT apparently you dont know any more than I do.But some where there has to be some one that could converse halfway intelligently with me about this.

Ummm Yeah. Sure.

See, they call that place you get those compressors a junkyard for a reason. Hard to say how much trash is in the system from all those failures...

You say you added oil - how much & what type?

Did you flush the system?

No mention of replacing the receiver dryer, or inspecting the TXV.

Your charging procedure is garbage. MVAC systems this small require precise quantities of refrigerant and oil.

Your pressures indicate something is way out of spec - at 2000 engine rpm on a conversion like that your high side is about 100 psi LOW Either your junkyard compressors are all shot, or you are grossly undercharged - which will fail to return lubricant to the compressor & turn it into trash.

Hack techniques and junkyard parts - hope you treat big chillers better.

WOW.

3 compressors and we're the issue. No need for a pissing match if you don't; value the suggestions of the forum members. Good luck on your project.

Well, you might be right that I don't know anything more than you, but I've never been without working air conditioning on any vehicle I've ever owned - including a vehicle I currently own that's the almost the same age (1984) as yours. But if you want to spent a summer of record heat recovering, removing, disassembling, reassembling (with junk parts), reinstalling, evacuating, charging and still not having air conditioning, then by all means enjoy the summer heat! Gotta admire your persistence though...
