tioned in line with the inner wheels. The outer
wheels should not contact the wood planks.
2. Engage the parking brake and shut off the engine.
3. Remove the key from the ignition switch.
4. Place wheel chocks in front and back of the
inner wheels to prevent accidental movement.
WARNING
Place wheel chocks in front and back of the inner
wheels to prevent the power unit from rolling dur-

A jack and jack stands may be used if planks are
not available.
Outer Dual Wheel Removal:
1. Loosen the draw bolts approximately 5 turns.
2. With a medium size hammer, hit the end of the
draw bolt until the draw cone releases.
3. Remove the dual wheel assemblies by rotating
counter-clockwise.
4. Install the plastic plugs from the dual wheel kit
into the inner dual wheel hubs on all four tires.
5. If desired, move the steering cylinder to the
inner hole setting of the cylinder mount under
the left front corner of the foot platform. Torque
to 150 ft-lbs (203 Nm).
Outer Dual Wheel Installation:
1. Remove the plastic plugs from the inner dual
wheel hubs.
2. Inspect the threaded end of the dual wheel
extensions to ensure the draw cone, draw bolt,
and the external threads of the dual wheel
extension have a light coating of grease. Apply
grease if necessary.
3. The draw cone must be loose before installing
the dual wheel extension into the inner hub.
Check by sliding the draw bolt in and out. It
should have 1/4” to 1/2” (6.5 to 13 mm) of travel.
4. Insert the threaded end of the dual wheel extension
into the inner dual wheel hub. Using both hands,
turn the dual wheel assembly clockwise until the
wheel is tight. Repeat for the other three wheels.
5. Tighten the draw bolt and torque to 120 ft-lbs
(163 Nm). Repeat for the other three wheels.

setting of the steering cylinder mount, move the
steering cylinder to the center hole setting of the
steering cylinder mount under the left front corner
of the foot platform. Torque to 150 ft-lbs (203 Nm).
