Another compressor problem

[Ryan Wright]

Hey Scott,

Where is the air dryer & relief valve on your coach? I had a problem
with mine sticking open in freezing weather and could not find it. I'd
like to get under there and check the valve heater and/or just replace
the thing.

Mine is on the centerline of the coach just forward of the drive
axle. You can't see it from the side, you have to get under the
coach.

Weee! Sounds like I get to go do some crawling around. Thanks for the info.

Ryan,

On the 1986 PT-40, the air dryer is between the tag and the drive
axle slightly right of center-line (if my failing memory is
correct). I still have the AD-2. I rebuilt mine with parts from
NAPA (dessicant, purge valve, check valve). There is a good rebuild
manual in the blue-box and can also be found on-line.

Good Luck,

Thanks, Glenn! I think I'll just go ahead and rebuild mine for the
heck of it. I don't see any mention of it in the maintenance records.

Ryan,

You can leave the Air Dryer mounted to the frame. The Dessicant
cartridge comes out of the bottom by removing a large nut. You can
refill or replace the dessicant cartridge. I replaced the cartridge
for about $30. There is also a heater rebuild kit if you feel yours
is not working and freezing up. Get the manual if you don't have one.
It has all the rebuild parts listed with part numbers. Let me know if
you have trouble getting a manual.
