CAUTION
Protect the fluid from being soiled by
impurities
When removing the old filter element, make
sure that power steering fluid doesn’t flush
back particles into the tank.
If this situation
occurs, contaminated fluid must be drained
and the tank must be cleaned.
13.4 STEERING SYSTEM PLAY
INSPECTION
Basically, the steering system play is checked
with the engine running and the front wheels in
the straight ahead driving position. The steering
wheel is slowly turned in one direction until there
is a perceptible movement of a front wheel. If a
point on the steering wheel rim moves more
than the value indicated below before
perceptible return movement of the wheel under
observation, there is excessive free play in the
steering system.
Steering wheel travel covered
Maximum
value:
1.732 inch (44mm) with
Prevost 18-inch steering
wheel
NOTE
The full procedure
is described under
paragraph
Checking the Steering Gear
Play in RB Robert Bosch Servocom - Service
Manual (8090 manual).
Take note that the maximum travel
covered value specified in the Servocom
manual doesn’t apply to the Prevost
design which uses a 18-
inch steering
wheel.
If the maximum value is exceeded, the steering
system should be thoroughly inspected for worn
or loose components, beginning with the
steering linkage. If the steering linkage is in
good condition, then the steering column and
the steering gear should be inspected.
