Steering Chain
The steering chains are very durable and,
properly lubricated, will last the lifetime of
the vehicle.
Inspect the chains for corrosion. Any sign
of corrosion is evidence of an improperly
lubricated chain and the chain should be
replaced.
Inspect each link in the chains for binding.
If any binding is found, remove the chain
and soak it in 30 wt. motor oil overnight and reinspect the links. Replace the
chain if the binding is not corrected.
INSPECT THE STEERING COMPONENTS
Steering Wheel and Bushings
1: After the steering wheel has been removed,
thoroughly clean the steering wheel shaft and bushings.
2: Measure the diameter of the steering shaft.
•
If the shaft diameter is not between 0.745” and 0.0750” then the
steering wheel should be replaced.
3: Inspect the surface of the shaft for unusual signs of wear.
•
The surface should be smooth with no pits or grooves. If any unusual
signs of wear are present, then the steering wheel should be replaced.
4: Inspect the slot for the retaining ring.
•
The retaining ring slot corners should be 90 degrees with a small
radius. If the corners are excessively rounded or the sides are tapered,
then the steering wheel should be replaced.
5: Insert the steering shaft back into the collar and check for lateral play
as shown to the right.
•
If the lateral play exceeds 0.010 inches then the bushings should be
replaced.

WARNING
Do not drive the vehicle while the steering wheel or
front wheels are tied in position. Driving the vehicle
while the steering wheel or front wheels tied in
position may cause loss of control of the vehicle
resulting in severe bodily injury and/or property
damage.
WARNING
Pillow Blocks
Note: The two pillow blocks will wear at the same rate. If one is worn
out, then both blocks should be replaced as a set.
1: Tie off the front fork so that it cannot turn.
2: While watching the steering shaft, rapidly rotate the steering
wheel to the left and right.
3: There should not be any discernible play between the steering
shaft and the pillow blocks. Any play indicates that the pillow block
is worn out and should be replaced.
4: Untie the front fork.
5: Reconnect the main positive and negative cables at the batteries.
6: Remove the blocks from behind the wheels.
7: Release the parking brake and test drive the vehicle.
