4. Prepare a new inner shaft seal for assembly. Put a
light coat of No. 1 Permatex (or equivalent) on the out-
side diameter (surface that contacts the axle housing),
and a thin film of oil on the inside diameter (surface that
contacts the axle shaft). Install the new seal to a depth
of 1.218 in. (30.90 mm) into the axle housing (Fig. 16).
5. Apply a 1/16" (1.60 mm) bead of Loctiter Ultra Gray
Silicone (gasket eliminator) to the axle housing flange.
Align the dust shield and brake assembly with axle hous-
ing flange and push the axle shaft assembly all the way
into the axle housing. Be careful not to damage the oil
seal and bearing (Fig. 17).
NOTE: Liquid Gasket Kit (Toro P/N 92-8775) includes
Loctiter Ultra Gray Silicone (gasket eliminator) and ap-
plication instructions.
6. Install socket head screws, hardened washers and
lock nuts. Tighten the nuts in an alternating pattern so
the bearing is drawn into the axle housing evenly (Fig.
18). Torque the nuts from 16 to 20 ft-lb (22 to 27 N−m).
IMPORTANT: When tightening the lock nuts, hold
the socket head screws with a wrench to prevent the
screw head from damaging the axle tube.
7. Slide the brake drum onto wheel studs. Retain brake
drum with lock nut (item 1).
8. Install wheel assembly on studs and secure with five
(5) lug nuts. Torque lug nuts in a crossing pattern from
75 to 80 ft-lb (102 to 108 N−m).
9. Secure brake cable to brake lever with clevis pin
(item 17) and cotter pin (item 18). Attach brake return
spring (item 19) to brake cable link (item 20).
10.Remove jack stands or blocking and lower machine
to the floor.
11. Adjust brakes (see Traction Unit Operator's Manu-
al).
