Air Dryer issue

[mbulriss]

Steve,

I assume that you have the Bendix AD-2 air dryer on there now. The
dryer cartridge assembly is like $30-35 plus a refundable core charge.
The spitter valve kit is like another $12-15 or so. Going from
memory on the prices since I don't have my log book with me, but those
are in the range of the parts I got last fall. The replacement
procedure should be in your blue box. It is basically a simple job,
three bolts to drop the dryer bottom plate, unscrew the filter, clean
the cannister, replace filter and bottom plate. If you do the spitter
valve also, you will probably need to put the end plate in a vise
between some wood pieces in order to get the big hex nut to break
free. Then just follow the instructions on the spitter valve rebuilt
kit. Just a few o-rings basically. Cheaper than going to the AD-9,
which as I recall will involve some re-plumbing of air lines.
