CLEANING & INSPECTION
1. Use a suitable solvent to clean all metal parts, and
use a cotton swab to clean the bore (Note: Do not use
abrasives or tools to clean the bore: any scratches
caused may necessitate replacing the Bendix
AD-IS air dryer & reservoir system.) Superficial
®
external corrosion and/or pitting is acceptable.
2. Clean the o-rings with a clean dry cloth. Do not use
solvents.
3. Inspect for physical damage to the bore and the check
valve seat. If the bore is damaged (by scratches,
etc. that would prevent the delivery check valve from
seating), replace the AD-IS air dryer.
4. Inspect the delivery check valve, o-rings, etc. for wear or
damage. Replace, if necessary, using the check valve
replacement kit available at any authorized Bendix
parts outlets.
5. Inspect all air line fittings for corrosion and replace as
necessary.
ASSEMBLY
1. Lubricate the smaller o-ring and check valve body with
a heavy-duty lithium grease.
2. Install this o-ring on the check valve body by sliding the
o-ring over the set of four tapered guide lands. The
o-ring groove holds the o-ring in its correct location.

3. At the other end of the check valve body, the spring is
installed over the set of four straight guide lands. When
the spring has been pushed to the correct location, the
check valve body is designed to hold the end of the
spring in position: be sure that the spring is not loose
®
before continuing with this installation.
4. Install the assembled check valve body/o-ring/spring
into the delivery port so that the o-ring rests on its seat
and the free end of the spring is visible.
5. Grease the adapter and the remaining larger o-ring and
install it onto the fitting.
6. Position the governor gasket, then insert the governor
mounting bolts through the governor and tighten (to
125 in-lbs). Note: Do not replace with a standard
compressor/governor gasket.
7. Re-attach the line to the governor.

8. Before placing the vehicle back into service, check
to see that the system pressure now builds to full
operational pressure.
