Bendix AD-4 Air Dryer Cartridge Replacement

Has anyone replaced this cartridge on a DIY basis?

It seems that one could buy a complete AD-9 for about $200 or a new AD-4 cartridge for about $50.

But, without a pit to operate from, access to my AD-4 Dryer would be tough with all the air removed from the suspension and the six wheels on 2x12 ramps about 6" high.

I suspect I need to dismount the entire dryer to change the cartridge?

Are there any tricks to this procedure that would help me DIY this maintenance?

Not sure how and where yours is installed but on my Winnebago UA, I used the hydraulics to jack the rear up then installed jack stands for safety. The dryer cartridge was very easy to replace. Once I got under there and studied it a little everything came apart and replaced nicely. If I remember right I did not have to dismount the dryer but it has been a while. Make sure you bleed the air!

air dryer

I have a 2001 Beaver Contessa and did the servicing on my air dryer myself.

I drained all the air from the system and stlii had enough room to lay under rear of coach and remove the filter and small inner coalescent to change, kit had a new valve for the bottom where air releases too...

took about 45 minutes to do it all. I just loosened bolts and tilted canister enough to get a grip on filter to loosen it.
