Nippondenso 6E171 reseal Q's

MikeC5 on Wed August 26, 2009 7:54 PM User is offlineView users profile

Year: 85
Make: Porsche
Model: 944
Engine Size: 2.5 L
Refrigerant Type: R-12
Country of Origin: Germany

A few questions for those who have experience taking this brand/model compressor apart for reseal. I mistakenly though the nuts/bolts holding the reed valves needed to be removed in order to get to the shaft seal. I soon found out it was simply the head plate stuck to the front cover. I did manage to keep the reed valves and backers in order (i.e. they are not mixed up). There does appear to be a little adjustment to align the reed valve with the hole in the plate. Is this uber-critical? I can eyeball it pretty well to get them centered but will the wear pattern already on them make it unlikely to seal properly?

The (3) cylinders look pretty good but not pristine. The shaft can easily be rotated by hand and there was plenty of clean looking oil in there. Should I worry about some light scuff marks? The compressor sat in storage for several years if it matters.

I haven't had any luck finding new gaskets/o-rings for the intake and discharge manifolds (bolted to the case) so I'm afraid to remove them. But if I don't remove them then I cant split the main case to replace the middle gasket. Is it a big risk to just leave it as-is and bolt it up again?

Might anyone have an exploded parts diagram/etc. of this unit? I can't seem to find anything on the web....

There was a link to exploded views of the common compressors, read this link but it appears dead nbow, maybe Tim can get it up again, or can supply with the exploded view you need..

To the original poster, check out Nippopn page 1 and 2 for the compressor you need from Tim's link, I didn't see the exact one which I believe is the 6E version, but most of them are the same as far as putting them together, so look closely and you should get an idea of what you're looking for.. Thanks tim...

Thank you for the link to the diagrams TRB. Any ideas on the reed valves? Is it a big no-no to disturb them?
