12. Install the assembled nut and axle into the
wheel on the side with the bearing and a new
seal (Figure 33).
13. Place the wheel with the open end facing
up and fill the area inside the wheel with
multi-purpose grease.
14. Install the second bearing and a new seal into
the wheel (Figure 33).
15. Apply thread locking adhesive to the second
spacer nut and install it onto the axle with the
wrench flats facing outward.
16. Torque the spacer nut to 75-80 in-lb (8-9 N⋅m)
then loosen it and torque it to 20–25 in-lb (2-3
N⋅m). Make sure the axle does not extend past
either nut (Figure 32).
17. Install the seal guards over the wheel hubs and
insert the wheel into the caster fork (Figure 31).
18. Install the caster bolt and tighten the nut
(Figure 31).
Important: Check the bearing
adjustment often to prevent seal and
bearing damage. Spin the caster tire. The
tire should not spin freely more than 1 to 2
revolutions or have any side-to-side play
between the caster fork. If the wheel spins
freely, adjust the torque on the spacer nut
until there is a slight amount of drag.

Servicing the Air Cleaner

Replace the air filter every 200 operating hours.
Note: Service the filter more frequently if
operating conditions are extremely dusty or sandy.
Removing the Filters
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set
the parking brake.
2. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
3. Release the latches on the air cleaner and pull
the air cleaner cover off of the air cleaner body
(Figure 34).
