ASSEMBLY - TURBO CUT-OFF VALVE
1. Lubricate all o-rings with the grease supplied in the
Bendix ® maintenance kits.
2. Install the large and small diameter o-rings on the
piston.
3. Install the turbo cut-off piston assembly in the body.
4. Install the o-ring on the turbo cut-off cap then install the
cap in the body.
5. Install the retaining ring in the body, making certain that
it is fully seated in its groove.
6. Before placing vehicle back into service, perform the
Operation & Leakage Tests detailed in this manual.
ASSEMBLY - PURGE/RELIEF VALVE
1. Lubricate the piston o-ring with the grease supplied in
the Bendix maintenance kit. Also, lubricate completely
around the outside edge of the purge valve.
2. Install the purge valve in the body. Make certain that it is
fi rmly and squarely seated in the body with the correct
side visible. Note: The three (3) "bumps" on the purge
valve should not be visible. If the three (3) "bumps" are
visible after the purge valve is installed, the valve must
be removed and re-installed.
3. Install the o-ring on the purge piston, then install the
piston in the body taking care not to cut the piston
o-ring.
4. Install the non-metallic exhaust cover and spring in the
body.
5. Install the retaining ring in the groove in the body. Make
certain that it is fully seated in its groove.
6. If so equipped, reconnect the exhaust line from the
exhaust port of the air dryer.
7. Re-tighten the supply port line.
8. Before placing vehicle back into service, perform the
Operation & Leakage Tests stated elsewhere in this
manual.
ASSEMBLY - HEATER AND THERMOSTAT
1. Lubricate the connector o-ring with the grease supplied
in the Bendix maintenance kits.
2. Install the o-ring on the connector, then slide the heater
and thermostat assembly into the body making certain
not to cut the o-ring. Note that the "tab" on the assembly
fi ts into the corresponding slot in the body.
3. Install the retaining ring in the groove in the body,
making certain that it is fully seated in its groove.
4. Apply a dielectric grease on the heater and thermostat
connector contacts (both the heater and thermostat and
vehicle wiring harness connector halves).
5. After making certain the accordion seal is in place on
the vehicle wire harness connector, connect the wire
harness to the heater and thermostat assembly on the
dryer until its lock tab snaps ("clicks") into place.
6. Before placing the vehicle back into service, perform
the Operation & Leakage Tests stated elsewhere in this
manual.
ASSEMBLY - DESICCANT CARTRIDGE
1. Lubricate the desiccant cartridge sealing ring with the
grease supplied in the Bendix maintenance kits and
replacement parts.
2. Screw the desiccant cartridge onto the body (by hand)
until the seal makes contact with the body. Rotate it
clockwise approximately one full turn. If necessary,
place a strap wrench or equivalent tool on the desiccant
cartridge next to the lip low on the cartridge.
Note: If the replacement cartridge is supplied with an
o-ring for the dryer threads, discard it. This o-ring is
not to be used.
IMPORTANT: If the cartridge removed was a Bendix ®
PuraGuard ® oil coalescing style cartridge, it must be
replaced with another PuraGuard-style cartridge.
3. Before placing vehicle back into service, perform the
Operation & Leakage Tests outlined in this manual.

body (identifi ed during disassembly). If the fi ttings were
removed from the body, use a thread sealant making
certain none enters the body during re-installation.
3. Apply a dielectric grease on the heater and thermostat
connector contacts (both the heater and thermostat and
vehicle wiring harness connector halves).
4. After making certain the accordion seal is in place on
the vehicle wire harness connector, connect the wire
harness to the heater and thermostat assembly on the
dryer by plugging it into the air dryer connector until its
lock tab snaps ("clicks") into place.
5. If so equipped, reconnect the exhaust line to the
exhaust port of the air dryer.
6. Before placing vehicle back into service, perform the
Operation & Leakage Tests stated elsewhere in this
manual.
