naumann,

Our W-22 is built on a 2004 Workhorse chassis. I have no idea if compressors changed over those model years or how many different compressors Workhorse actually used during that time. I do know that there are several that seem similar. One difference I noticed was pulley diameter, so if you go searching, that's a good thing to know.

I had to go to several different auto parts places near me before I finally found someone that could really dig deep and was willing to special order a unit for me (at no charge if it wasn't the right one). Fortunately, it was. The compressor I installed in my rig was a Everco-4Seasons 2651N (58950).

You might check out Oemy's to get a list of possible compressors. They've added a few numbers since I needed them about 4 years ago, though its funny I don't see 58950 listed, but they DO have 88950.

On Edit: OK, strange. When I type 58950 into the Autozone Website, it returns a compressor with the number of 620151 from CompressorWorks, which IS a number on Oemy's site.

If the system has been opened to the atmosphere for any length of time, you should also replace the Receiver/Drier. THAT is also a tough part to hunt down as there are various styles and shaped in terms of how the hoses connect.

If your problem is a failed clutch, you might have a shot at replacing just the clutch. That was originally my problem (the clutch seized). But in trying to remove the clutch, the front seal was damaged, so at that point, I just decided to change the entire compressor. A much more involved process, for sure, but not too bad if you have any A/C experience and the right equipment.

Good Luck,

~Rick

They have heavy duty which you need as a complete system replacement. They are nice units that have lasted.

Hi,

In addition to specifying which part needs to be replaced/repaired, it would also be helpful if you could tell us which chassis your motorhome is built upon. Gas (Ford or Workhorse) or diesel (I have no idea if any Dolphins were on diesel chassis', and if so, whose?).

Some parts of the A/C system are typically supplied by the chassis manufacturer (compressor & condensor) and others are fitted by the coach builder (control panel, evaporator) oftentimes supplied by a third party (Evans-Tempcon for example), so all of the information is needed to give a good answer.

And yes, finding the right part can be a challenge. I needed a new compressor for mine a few years back and it took some creative searching to find the right compressor to replace the original WITHOUT paying outrageous Workhorse prices.

There is not one part# for the entire unit. Which part doesn't work?
