Toro Greensmaster 3100 Installation Instructions page 2

11. Install remaining snap ring into the shaft groove. Slide
remaining new grease seal onto motor shaft.
Important
The hub should spin freely in the forward
direction, but lock on the hydraulic motor shaft when it is
spun in the reverse direction.
12. Press the grease seals into the hub so they are flush with
the ends of the hub.
Modify Castor Fork
1. Mount the drill guide to the left side of the castor fork
with (2) 5/16 x 3 in. bolts, (4) 3/8 x 7/8 washers and
nuts. Position the components as shown in figure 3.
2. Using remaining hole in drill guide, enlarge hole in
castor fork to 9/16 in.
Important
It is highly recommended that a new or
recently sharpened 9/16 in. drill bit be used. Proceed slowly
when drilling. Do not use excessive force when drilling as
jamming may occur.
3. Move the fasteners to the other holes in the drill guide
and repeat the process until all (3) holes are enlarged.

Install Motor and Hub
Assembly
1. Mount the tire assembly to the motor and hub assembly
with 4 lug nuts. Torque lug nuts to 70 to 90 ft-lb (95 to
122 N⋅m).
2. Re-install the grease fitting to the hub assembly,
pointing it away from tire.
3. Insert flangettes and bearing onto end of motor shaft as
shown in Figure 4.
4. Mount the (2) straight fittings to the side of the motor
assembly (Fig. 4).
Note: Make sure all O-rings are lubricated and in position
before installing fittings.
5. Position the motor hub, flangettes with bearing and tire
assembly into castor fork. Ensure that ports on motor
face rearward (Fig. 4).
6. Loosely secure motor to the inside of caster fork with
(2) socket-head screws and (2) nuts (Fig. 4).
7. Tighten motor screws to 100 ft–lbs (135 N
m).
8. Loosely assemble flangettes with bearing to inside of
castor fork with (3) new 3/8 x 2 in. screws, (2) spacer
mounts, (3) 13/32 x 13/16 hardened washers and (3)
3/8 in. locknuts.
Important
shaft.
Note: The grease fitting must be in the downward position
on the flangette (Fig. 4)
9. 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.

10. Apply a thread-locking adhesive (such as Loctite
bearing setscrews and torque to 80 to 100 in-lb (9 to 11
N⋅m).
11. Verify overrunning bearing operation: The tire should
roll freely forward, but engage wheel motor when rolled
backward.
12. Lower rear of traction unit to ground.
13. Grease all fittings with No. 2 general purpose
lithium-based grease.
14. Re–connect the hoses to the fittings.
