Good afternoon,
When I bought this thing I thought it was a recreational vehicle but I must have misunderstood and its really called a vocational vehicle because I'm always doing maintenance on it.
No seriously I like working on it. Know its done right and saves a good deal of money also.
Now to the point of the post.
Changed out the air dryer filter on our 2004 HR Ambassador and I wanted to post the part numbers in case someone else needs them. Might save you some of the hassle of finding the right parts if you have this type air dryer.
Had to do a little research to get the proper part #'s since they aren't listed but eventually I found them.
IF you have a Meritor/Wabco system saver 1200 air dryer then your part # is R950011. Since my local truck parts store didn't have the Meritor Wabco filter I put a another brands filter on. Made by In line for PACCAR parts and the part # is ADSP-CART. This filter replaces several others including the one listed above for the OEM.
Hope this helps.
As far as the change out itself I don't think HR could have put it in a more difficult place, right in the middle of the motorhome just forward of the rear wheels. That being said I used a strap wrench and it came off without to much trouble. Cleaned up the seat, regreased the seal on the o-ring and seal and reinstalled the new one. Aired the system up and works like its supposed to.
Cost $52.00. Time spent changeing it about 45 minutes which includes puting wood blocks under the frame for safety, jacking it up using the hydraulic jacks and running up the air from completely empty.
Hope this helps someone.

Excellent work. And down-right satisfying to know it got done right, I bet!

Good info. Glad I did a search because I was having real trouble finding a source for a R950011 part.

I found the replacement part ADSP-CART that you recommended.

Since it was some time since this subject was brought up for the Meritor Wabco System Saver 1200, I figured someone else may need it too.

I found the ADSP-CART part at:

PeterbiltPartsStore.com - Product Catalog - Search Result Page

Cost was 49.99 + shipping.

I also found a good set of instructions:

The local PeterBilt is where I bought mine as well. About every 4 to 6 weeks they put it on sale for about $35

About how often should the air dryer filter should be changed?

My Owner's Manual says every 2 to 3 years.

Glad you brought this item up. I noticed I changed mine in 06'. I suppose it's about time to change it again for a little piece of mind. The Wabco cost $45 back in 06' at a local truck parts store. I wonder what it will cost now....Good luck with your replacement.
