I always get the complcated ones, now the COMPRESSOR leaks!

I replaced the evaporator on the TE a couple weeks ago and though I was through with the job. Pumped down nicely, no leaks, worked like a charm.

Last Sunday on the way to the family reunion I had no AC. Sure enough, no charge. What a pain in the butt!

No vac this time, so blew in 40 psi of R134a and went sniffing. Big leak at the manifold connection. Got new seals, pulled the Reciever/dryer lines and replaced those o-rings too just in case, still won't hold a decent vac.

I'm thinking hose manifold by now, and my wallet is screaming (stupid thing costs a huge pile instead of having hose fittings, grrrr!).

Blow in some more 134a and I can HEAR it leaking -- right out the seam in the middle of the compressor!!!!! Oil everywhere.

Ho boy, do I get to spend money! However, I did some poking about and it appears that a set of gaskets and seals is pretty cheap.

Anybody ever taken one of these apart and replaced shaft seal and body o-rings? I don't see any reason to replace it instead of doing a quick rebuild,not to the tune of $700 anyway!

My friend Hans happened to have a 10P15C compressor sitting in the shop with a fried clutch, otherwise fine that a customer wanted replaced with a new compressor, so I'm OK there (except I suspect the shaft seal leaks on that one, oil on the front end.

Any thoughts welcome!

Peter

Fairly simple to rebuild the compressor body, takes the right tools to do the front seal properly, however. And get OE parts from Toyota (about the only place to get OE denso parts), not an aftermarket kit. The body kit lists for ~$80, same for the front seal kit.

Compressor body splits somewhat easily after removing front allen bolts, just remove the front end down to the shaft, and remove keyway CAREFULLY, so you don't ruin the front seal. I think the rebuild info is in the 124CH Climate Control manual; if not there, it's in one of that vintage of manuals.

Thanks!

I found the front seal replacement instructions, but not the body seal ones, although I think the only other steps would be taking the body apart. The stuff I found on the web said don't take the rear body off unless you have the two halves together, that way the swash plate won't come out.

Aftermarket kit is tempting ($25), but if you recommend Toyota/ND OEM, I'll do that, it's too much of a PITA to do twice.

Yah, done it both ways, and I've never had trouble with the OE parts (not so w/ the econo-kits...)
