W114 York a/c

Hi,
I have managed to take the York compressor out which work for a little after a filled it with freon.
It was making unusual noises and robbing tons if power from the engine.
Here are few pics, I see no wear but I don't know how an a/c wear looks like

What should I check now that I have it out?
Can I rebuild this monster?
Is there a kit for it?

Or is it better to search for a replacement like sanden?

Tons of space in the engine bay now.
Thank you

That sounds better than redoing it myself
What is usually "fixed" when these units are redurbished?

Why not convert to the sanden compressor. There are conversion kits. Do a google search.

Probably same as rebuilding anything; strip, check tolerances, new seals, gaskets, rings, etc, reassemble, paint and test.

Better to use a Sanden or the ND unit as used in later models as original.
Quite compact and vibration free and very efficient.

Sanden (507) for sure.

Beware: most cheap ones you see are knock-offs from China, and their mounts differ in quality. (There are kits that come with York adapters, since it is such a worthwhile and popular swap)

What gets refurbed most often on the Yorkshire are piston seals and the inlet/outlet valves. Worth the trouble? Depends on the cost of labor where you are.

Kavadarci,

Detailed, accurate information concerning this York AC compressor rebuild and all of your other "how to" questions are in the factory service manuals for the item in question.

Those manuals are an excellent investment or are often available at public libraries, either directly or through inter-library loans. They spell out how to do the job(s) properly. To actually get it done properly it's generally necessary to do the job(s) ones self.

You can be assured that a $100 "Rebuilt" compressor has had whatever broken part kept it from working replaced, possibly with a used part, and a new coat of paint applied. The fixed business costs, the labor to disassemble a compressor and parts costs to replace all of the moving parts with new parts (a true "rebuild"), and profit would vastly exceed $100, wouldn't it?

My 1971 Dodge van that I bought new uses an RV-2 compressor that, although 2 cylinder, is similar in function to your York compressor and the 2 even share the same front crankshaft seal. Those old school compressors seem indestructable as long as the oil level is maintained but the front seals do wear out at intervals of about 50K miles. Because the seal is in a removable seal plate the seal can be replaced without removing the compressor. They do require more power to run than modern rotary compressors. The AC system in my van is still shooting isicles at 42 years of age and 348K miles, so those dinosauers do get the job done reliably.

You always have good answers,
Thank you


This a/c compressor is a monster no doubt about it
It has more power than the little motorcycle I used to have as a child :-)

I will think about the options here
Time is my enemy I don't have the needed time to dedicate on a proper rebuild
