INSPECT THE STEERING COMPONENTS
Steering Wheel and Bushings
After the steering wheel has been removed, thoroughly
clean the steering wheel shaft and bushings.
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.
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.
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.
Steering shaft and sprocket
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.
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.
