AC Compressor front seal leak?

[fjgdk]

As Rex said, that's most likely where the o-rings go, but sometimes they send too many o-rings. If you removed the manifold plate on top of the compressor, then you didn't mess with the two o-rings where the lines connect.

Nothing against you, Rex, but there is no way I'd recommend buying a new Denso compressor to anyone, especially a 10s series. In fact, I've told customers I will not sell them one b/c I do not trust the reliability, nor want the liability. Quality went downhill at Denso, and if was NOS 10P series, I'd worry about dried out seals.

Luckily there are places such as the aforementioned Santech, and Omega (how is that lady still in business??) that can hook us up.

I guess they changed their numbers at Santech, part #K20-3115 is the shaft seal kit I used to seal 6P148's, which is the compressor for the FJ60. This kit also seals the 10P and 10PA series compressors, and probably the 6E171's, but I can't remember for sure. Use emery cloth or very fine sand paper to smooth the rough spots on the shaft or you'll be doing it again. Lightly coat the parts with oil prior to installation.

IMHO, the 10P series compressors are the best ever manufactured, we are lucky.

Just watched the videos, he broke the cardinal rule in rebuilding compressors. You can see where the old seal rode on the shaft, he didn't pay any attention and neglected to clean it up. He might have a leaker on his hands.

Hey you seem to be pretty knowledgable about compressor rebuilds, I hope you could give me some tips.

1) I was wondering if you knew of any seal kit for the 6P148 that would facilitate an r-134 conversion ?
2) In doing an r-134conversion, what is the best way to flush or clean the compressor of the r-12 - friendly mineral oil such that PAG can be used ? Flushing all the other components is more straight forward to me than how to get the compressor cleaned of the old stuff which is why I am asking.
3) Lastly, assuming I do a complete flush of old mineral oil from the whole system and change over all seals and valves, what about of PAG oil and R134 is appropriate in doing a retrofit ? According to the AC repair manual for my FJ60, the AC system took a total of 170cc of mineral oil and 1.45-1.65 pounds of R-12. What would be the amounts of PAG oil and R-134 respectively ?
