STEERING - Service Adjustment Procedures
STATIONARY STEERING EFFORT CHECK
1. With the vehicle stopped on a flat, paved surface, turn the
steering wheel to the straight ahead position.
2. Start the engine and set it to 1,000 + 100 rpm.
Caution
After checking the engine speed, there must be a return
to the standard idling speed.
3. Attach a spring balance to the outer circumference of the
steering wheel and measure the steering force required to
turn the steering wheel from the straight ahead position to
the left and right (within a range of 1.5 turns).
Also check to be sure that there is no significant fluctuation
of the required steering force.
Standard value:
STEERING WHEEL RETURN TO CENTER CHECK
To make this test, conduct a road test and check as follows.
1. Make both gradual and,sudden turns and check the steering
"feeling" to be sure that there is no difference in the
steering force required and the wheel return between left
and right turns.
2. At a speed of 35 km/h (22 mph), turn the steering wheel
90". and release the steering wheel after 1 or 2 seconds. If
the steering wheel then returns 70" or more, the return can
be judged to the satisfactory.
NOTE
There will be a momentary feeling of "heaviness" when the
wheel is turned quickly, but this is not abnormal. (This is
because the oil pump discharge amount is especially apt to
be insufficient during idling.)
V-BELT TENSION CHECK
Check to be sure that the belt is not damaged and that the
V-belt is correctly attached to the groove of the pulley.
NOTE
If there is abnormal noise or belt slippage, check the belt
tension and check for unusual wear or abrasion, or damage, of
the pulley contact surface, and for scars or scratches on the
pulley.
