8.
Pack the bearings with a general-purpose
grease.
9.
Insert 1 bearing and 1 new seal into the wheel.
Note:
Replace the seals.
10.
If the axle assembly is missing both spacer nuts,
apply a thread-locking adhesive to 1 spacer nut
and thread it onto the axle with the wrench flats
facing outward.
Note:
Do not thread the spacer nut all of
the way onto the end of the axle. Leave
approximately 3 mm (1/8 inch) from the outer
surface of the spacer nut to the end of the axle
inside the nut.
11.
Insert the assembled nut and axle into the wheel
on the side of the wheel with the new seal and
bearing.
12.
With the open end of the wheel facing up, fill
the area inside the wheel around the axle full of
general-purpose grease.
13.
Insert the second bearing and new seal into the
wheel.
14.
Apply a thread-locking adhesive to the second
spacer nut, and thread it onto the axle with the
wrench flats facing outward.
15.
Torque the nut to 8 to 9 N∙m (75 to 80 in-lb),
loosen, then torque to 2 to 3 N∙m (20 to 25 in-lb).
Note:
Make sure that the axle does not extend
beyond either nut.
16.
Install the seal guards over the wheel hub, and
insert the wheel into the caster fork.
17.
Install the caster bolt and tighten the nut fully.
Important:
To prevent seal and bearing damage,
check the bearing adjustment often. Spin the
caster tire. The tire should not spin freely (more
than 1 or 2 revolutions) or have any side play. If
the wheel spins freely, adjust the torque on the
spacer nut until there is a slight amount of drag.
Apply another layer of thread-locking adhesive.
Engine Maintenance
WARNING
Contact with hot surfaces may cause personal
injury.
Keep your hands, feet, face, clothing and
other body parts away the muffler and other

Engine Safety
Shut off the engine before checking the oil or adding

or sandy conditions).
Every 250 hours—Check the safety air filter.
Every 500 hours—Replace the safety air filter.
Note:
Check the filters more frequently if the
operating conditions are extremely dusty or sandy.
Removing the Filters
1.
Disengage the blade-control switch (PTO), move
the motion-control levers to the N
