View Full Version : York YCWS DXS motor term repair.

On the DXS style compressors is it necessary to remove the suction cover to replace a leaking o-ring on motor term stud?
If anybody has done this repair before, any info would be appreciated.
I have all the parts lit, but have never done this repair before.

The terminal seal should be between the top of the terminal block and the upper insulator, all external to the compressor. Since these have a cast terminal block, there is an insulator on the entering side (internal to the compressor). Take the nuts off the terminal bolt and you should be able to get to all you need. Bolt shouldn't fall into the compressor, but take care just in case. Never was very fond of the way these are built, mainly because everything sweats and deteriorates due to the cast block.

Well I got the first compressor done. Went down to Sears and got an automotive seal pick set with 8 inch handles. There were 4 or 5 different types in the set.
The one that worked best to get the seal out was the 90 deg style.
I was able to stab the rubber and lift it out without removing the suction cover.
I am going back tomorrow to do the other Comp. I will have to pull the suction cover on this one as I need to replace the o-rings on the temp sensor terminals also.
I understand there is a spade connection on the inside, and wires are tie strapped together, I'll let ya know how it goes.

Those picks are great they have saved the day for me many times , I have changed the thermistors without removing the suction end cover and yes they are a double sided spade wires are short.

Unscrew the terminal and pull it up to access the spade. If you can't get to it, then pull the cover.

Well I got parts fornicated today by York/JCI? The Item # for the temp sensor term o-ring was listed as #13 in the parts pub.
Should have been #19.
Terminal is 7/16", #13 O-ring is 9/16" #19 is 7/16" FYI.
Baltimore said that I have the latest form # so I suspect there may be another revision coming soon, then again maybe not.
At least they agreed to send me the new .45 cent o-rings NDA, but no help on the lost labor $$.
I dropped the suction cover, and it didn't take all that much more time.
The hardest part is getting all that rubber tape off the motor terminals.
I don't know if I would recommend doing the temps sensors without pulling suction cover first. I guess in a pinch you could do it, but it seems like the wires could get some pretty good twists in them.
