I guess it's possible that while your Mountain Aire is a 1996 the chassis might be a 1995 or a 97. To find out, do a VIN search:

Ford VIN decoder - Lookup and check Ford VIN number and get options and specs for free. Search Ford history, price and car loans.

Also, I see that you have a 3760 Mountain Aire. I don't know if you received all the manuals/info sheets when you purchased your motor home but I have most of them for mine. I also have the VCR tape that does a generic walk thru of a Newmar that came with them when new. For example, are you aware that the back bumper slides out to hold a spare tire. I copied the tape to a DVD, it's very informational, send me a PM and I would be more than happy to send you a copy.

This thread has pictures of an F53 compressor like yours. It might have info that will help.

The clutch and the compressor are both seized. I know that sounds unlikely. I already took it apart. I had to beat the pulley off with a hammer. The internal shaft of the compressor is also seized. That doesn't matter too much if I could get a new bearing and have the pulley spin with the clutch disengaged.

Still need to figure out which part it is to get a new clutch and pulley. F53 clutch does not fit at all.
You should be able to press out the old bearing using an arbor press or hammer and punch. If you go the hammer and punch route make sure you put the punch on the outer bearing race. Tap on the punch in several locations around the perimeter so the bearing doesn't get wedged in the bore.

Over the years I've replaced dozens of them without problems. The outer race should have a number etched into it. It should be the universal bearing number. Any manufacturer that makes a replacement bearing should have the exact same number. The bearing should be available from almost any auto parts store. I used to buy them from NAPA.

So im in the same boat on the compressor issue and neither above look like mine. I have a 1997 F53 (Bounder) and on the top of the complressor there is a hose that threads on with a bad seal. I even drove the camper to the Ford dealer and they can't match it up with any. I am fairly confident this is original but still searching for a seal. Mine is much larger and has no tags or names that we can find on it. I'll try to take a picture later today. It works fine just leaks from the fitting so i continually have to add freon.

Okay. Here is a picture of the compressor that is in fact the correct one for my rig. Available on eBay here

No one could figure out which compressor fit, not local rv places, not Ford, not Napa or other auto parts stores. I did not call Newmar but one of the rv places said they did.

I found it by simply searching for Ford ac compressors on Google images and going through pictures.

Napa and Ford confirmed it is a compressor used in motorhomes in 96 but only after I gave them the part number. Discontinued by Ford. Napa said they would not have been able to find it without the number. Part number is F4TD19D629AA

Yours is larger than this?

Many RV brands have "Owners clubs" and most times there is very good technical information. Try this: Newmar Kountry Klub - King Aire : Essex : Mountain Aire : Dutch Star

However, finding parts for it has not been fantastic.

According to the newmar brochure and looking at the layout of the vehicle it is an MA3760

It has a ford 460. The brochure says it is a Ford chassis. I see everyone talking about the Ford F53 motorhome chassis.

However, I need a new AC compressor. Everything I find online, the guys at NAPA and other auto parts stores all say it should be one compressor, but it is something very different. I do not know to find parts for it.

Was there another Ford Chassis available in 96 other than the F53?

If this is an F53 chassis why does it have a different AC compressor than everyone says it should have? How can I find the right one?

Any help would be fantastic.
