I have a 2006 Holiday Rambler Vacationer on a workhorse Chassis and in need of a new AC Compressor, what parts are needed for a complete replacement and appx purchase price? ( Joseph Chizek, 06/12/2019 )

The part # for the A/C compressor is CS0120-11B1 and it comes with the seals you need when replacing it. I would recommend replacing the receiver dryer at the same time, part # is W8007308: https://www.ultrarvproducts.com/W8007308-Receiver-Drier-Asm-2005-2006-W-series-(No-Bracket)

Is a replacement clutch available for this? I don’t want to open the system just to replace a noisy clutch bearing. ( Joseph Moseley, 06/01/2019 )

No, the clutch is not available separately through Workhorse.

when compressed fails does it fill system with metal my belt clutch still in gauges will i need an expansion filter as well?

Whenever you service the a/c system you should replace the receiver drier and expansion valve.
