Removal (Fig. 3)
1. Have ProCore Processor attached to tow vehicle
and park machines on a level surface. Engage vehicle
parking brake, stop engine and remove key from the
ignition switch. Make sure that Processor engine is off.
Chock wheels to prevent movement of either machine.
2. To prevent unexpected blower operation, disconnect
the negative battery cable from the battery terminal.
Position disconnected negative cable away from the
negative battery terminal.
3. Jack or hoist blower from ground and support with
jack stands (see Operator's Manual and Jacking In-
structions in Chapter 1 − Safety).
4. Remove wheel assembly (see Wheel Removal in
this section).
5. Carefully pry dust cap from wheel hub.
6. Straighten cotter pin and remove from axle spindle.
7. Remove nut retainer, jam nut and tab washer that se-
cure wheel hub to spindle. Slide wheel hub with bearings
from spindle.
8. Disassemble wheel hub:
A. Remove grease seal from the wheel hub taking
care to not damage the hub bore. Discard seal.
B. Remove bearing cones from both sides of wheel
hub. Clean bearings in solvent. Clean inside of hub.
C. If necessary, remove bearing cups from hub.
D. Inspect wheel bearings. Check the bearing cones
and bearing cups for wear, pitting or other damage.
Replace worn or damaged parts.
9. Inspect axle for wear or damage. Replace axle if nec-
essary.
Installation (Fig. 3)
1. Thoroughly clean all wheel hub components before
assembly.
2. Assemble wheel hub:
A. If bearing cups were removed from the wheel
hub, press inner and outer cups into the hub until
they seat against the hub shoulder.
B. Fill hub approximately 50% full of grease.

C. Pack both bearing cones with grease. Install
greased inner bearing cone into the cup on inboard
side of the wheel hub.
IMPORTANT: The grease seal must be pressed
in so it is flush with the end of the hub. The lip of
the seal must face the inner bearing.
D. Lubricate the inside of new grease seal and press
it into the wheel hub.
3. Install the wheel hub onto the axle spindle taking
care to not damage grease seal in hub.
4. Install greased outer bearing cone, tab washer and
jam nut onto spindle shaft.
5. While rotating the wheel hub by hand, torque the jam
nut from 75 to 180 in-lb (8.5 to 20.3 N−m) to seat bear-
ings. Loosen nut until it is away from tab washer and hub
has end play. Finally, while rotating hub, tighten jam nut
from 15 to 20 in−lbs (1.7 to 2.3 N−m).
6. Install nut retainer and cotter pin to secure jam nut.
Install dust cap to hub.
Failure to maintain proper lug nut torque could
result in failure or loss of wheel and may result in
personal injury.
7. Install wheel assembly (see Wheel Installation in this
section).
8. Carefully lower machine to ground. Make sure to
properly torque wheel lug nuts from 60 to 65 ft−lb (81
to 88 N−m).
9. Connect negative battery cable to negative battery
terminal. Tighten nut that secures battery cable from 10
to 15 ft−lb (14 to 20 N−m). Make sure that battery cover
is secured.
