Install Brake Assembly (Fig. 2)
1. Make sure that internal retaining rings are fully
seated in grooves inside splined brake coupler (item 2).
Slide splined brake coupler into brake assembly. Note:
The stepped endof the coupler must be installedtoward
the hydraulic wheel motor (Fig. 4).
2. Apply Loctite Gasket Sealant #2 (or equivalent) to
sealing surfaces of new gasket (item 7). Apply gasket to
brake assembly.
3. Position brake assembly to frame, aligning splined
brake coupler with input shaft on planetary wheel drive.
4. Install four (4) flange head screws to secure brake
assembly to frame. Torque screws in a crossing pattern
from 75 to 85 ft--lb (101 to 115 N--m).
5. Secure brake lever (item 14) to brake pull rod:
A. Position brake lever so that brake lever slot fits
around pull rod on brake assembly (Fig. 6).
B. Place two (2) washers (item 16) between brake
lever and frame bracket (Fig. 5).
C. Slide clevis pin (item 17) through frame bracket,
washers and brake lever.
D. Secure brake lever to front axle frame with cotter
pin (item 13).
E. Make sure that brake lever rotates freely after as-
sembly.
6. Install new o--ring on hydraulic wheel motor. Install
wheel motor and torque cap screws from 75 to 85 ft--lb
(101 to 115 N--m) (see Front Wheel Motor Installation in
the Service and Repairs section of Chapter 4 -- Hydrau-
lic System).
7. Install front wheel assembly.
Failure to maintain proper wheel lug nut torque
could result in failure or loss of wheel and may
result in personal injury.
WARNING
8. Lower machine to ground. Torque wheel lug nuts in
a crossing pattern from 70 to 90 ft--lb (95 to 122 N--m) .
9. Make sure drain plug is installed in bottom of brake
assembly. Fill planetary wheel drive/brake assembly
with SAE 85W--140 gear lube to proper level. Capacity
is approximately 16 fl. oz. (0.47 l) per wheel.
10.Check and adjust brake cable for proper brake op-
eration. Brake lever should be from 0.470” to 0.530”
(12.0 to 13.4 mm) from brake casting surface when
brake is disengaged (Fig. 6).
