Insert flangettes and bearing onto end of motor shaft
as shown in Figure 2.

5.
Mount the 2 straight fittings to the side of the motor
assembly (Figure 2).
Note:
Make sure all O-rings are lubricated and in
position before installing fittings.
6.
Position the motor hub, flangettes with bearing, adapter
plate and tire assembly into castor fork.
Note:
Ensure that ports on motor face rearward
7.
Loosely secure motor to the inside of caster fork with
2 socket-head screws and nuts (Figure 2).
8.
Tighten motor screws to 100 ft-lbs (135 N-m).
9.
Loosely assemble flangettes with bearing to inside of
castor fork with 3 new screws (3/8 x 2 inch), adapter
plate, spacer mount, 3 hardened washers (13/32 x
13/16 inch), and 3 (3/8 inch) locknuts (3/8 inch).
Important:
Make sure no radial load is put on the
motor shaft.
Note:
The grease fitting must be in the downward
position on the flangette (Figure 2).
10.
Tighten the flangette screws to 40 ft-lbs (55 N-m).
Note:
Failure to carefully follow the above assembly
sequence may result in premature motor seal and
bearing failure.
11.
Apply a thread-locking adhesive (such as Loctite
®
) to
bearing setscrews and torque to 80 to 100 in-lb (9 to
11 N-m).
12.
Verify overrunning bearing operation: The tire should
roll freely forward, but the wheel motor will engage
when rolled backward.
13.
Lower rear of traction unit to ground.
14.
Grease all fittings with No. 2 general purpose
lithium-based grease.
15.
Apply a decal to each side of caster fork (Figure 2).

Installing Hydraulic
Components
No Parts Required
Procedure
1.
Disconnect the negative cable and then positive cable
from battery.
2.
Drain all hydraulic oil from reservoir by removing the
upper hose from pump (Figure 4). Re–connect hose
after installing hydraulic hard line.
Note:
The hydraulic system capacity is approximately
8.5 gallons (33 liters).
Important:
Take care not to contaminate oil if you
are going to reuse it. A very small amount of dirt
or debris can severely damage hydraulic system.
3.
Disconnect the hose from the 90 degree fitting at the
L1B port on the hydraulic manifold (Figure 3). Note
angle at which fitting is directed.

Remove the 90 degree fitting from the hydraulic
manifold and replace it with the 45 degree fitting
(Figure 3). Position the fitting at the approximate angle
the previous fitting was installed.
