Assembly of the Axle Housing
Components with Central Actuation
Wet Disc Brake Feature Option
WARNING
Use straps to lift axle housing into safe axle work-
stand with lifting straps. Care should be taken to
secure the axle housing so personal injury or com-
ponent damage does not occur.
WARNING
Take care when using lifting devices. When
you use a lifting strap, inspect the strap for
damage before you use it. Do not use a lifting
strap to shock load or drop load a component.
Serious personal injury and damage to
components can result.
1. Using lifting straps ,safely lift the clean axle housing
and place in axle stand with carrier bowl opening fac-
ing forward to assemble brake tubing components if
axle has the central actuation wet brake option. If the
axle is without central actuation wet brakes, skip to
“Install Carrier into Axle Housing Assembly”
section.
If the axle being assembled has the wet disc brake
central actuation port option, follow the recommended
assembly procedure. Should the axle being assembled
not have a central actuation wet disc brake option, skip
to the next section. Figure 4.1.

1. If the central actuation hydraulic inlet port was previ-
ously removed from the axle housing, apply high
strength thread-locker to M22 threads of hydraulic
inlet port and insert into the top or front of the axle
h
ousing near the carrier area.
NOTE: The internal hydraulic tee-fitting (see page 5)
may be used to install the hydraulic inlet port by applying
oil to the tee threads and screwing the tee fitting into the
flange side of the port using it to turn in the hydraulic
inlet port until hydraulic port is fully installed. Refer to
“Torque Table” in section 6.
NOTE: It is recommended that before removing the
hydraulic tee-fitting or special tool to wait at least 15
minutes to allow the thread locker to become effective.
2. Apply oil on the thread of the tee-fitting, if using it as a
temporary tool.
3. The tool should be removed from the inlet port once
the port is installed, after waiting a minimum of
15 minutes.
4. Before installing the hydraulic tee-fitting into the axle
housing, back off the jam nut against the shoulder
and install the tee-fitting into the inlet port inside the
carrier bowl by hand tightening and then slowly
loosen tee to align with direction of both hydraulic
brake tubes.
NOTE: These brake tubes will only fit correctly installed
into the correct side of the axle housing. If previously
marked during disassembly, this would assist in re-
assembly in correct positions.
5. Insert both the brake tubes and fittings at the same
time from each of the axle flange ends to optimize the
fit into the axle housing.
NOTE: The brake tubes have threaded hydraulic nuts
on each end.
6. Hand -tighten each brake tube assembly to the
hydraulic tee.
7. Hand tighten each brake tube assembly on the banjo
fittings aligning with the ports in the axle housing.
NOTE: Care should be taken to not exceed the
recommended torque value and over stress the other
connections in the tubing assemblies.
