5. Mount the (2) straight fittings to the side of the
motor assembly (Figure 3).
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.
Ensure that ports on motor face rearward (Figure 3).
7. Loosely secure motor to the inside of caster fork
with (2) socket-head screws and (2) nuts (Figure 3).
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 3/8 x 2 inch screws, adapter
plate, spacer mount, (3) 13/32 x 13/16 hardened
washers and (3) 3/8 inch locknuts.
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 3).
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 engage wheel motor
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 3).
