SERVICE ADJUSTMENT PROCEDURES

STEERING WHEEL FREE PLAY CHECKNlSFABH
1. With engine running (hydraulic operation), set front wheels
straight ahead.2. Measure the play on steering wheel circumference before
wheels start to move when slightly moving steering wheel
in both directions.
Limit: 30 mm (1.2
in.13. When the play exceeds the limit, check for play on steering
shaft connection and steering linkage. Correct or replace.
4.If the free play still exceeds the limit value set steering wheel
straight ahead with engine stopped. Load 5
N (1 lb.1 towardssteering wheel circumference and check play.
Standard value (steering wheel play with engine
stopped): 11 mm
I.43 in.)
If the play exceeds the standard value, remove steering gearbox and check total pinion torque.
STEERING ANGLE CHECKN19FDBJ1. Set front wheels on turning radius gauge and measure
steering angle.Standard values:
Turbo
Inner wheel
31”30’+2”Outer wheel
27”OOOther models
Inner wheel
35”00’_+2”Outer wheel
2990’
2. When not within the standard value, it is probably a toe
problem. Adjust toe (refer to GROUP 2-Service Adjustment
Procedures) and recheck.TIE ROD END BALL JOINT VARIATION CHECK
(SHAFT DIRECTION)N19FVA8The inspection procedure for the tie rod end ball joint variation
is the same as for the manual steering system. (Refer to
P. 19-7.)
TIE ROD END BALL JOINT STARTING TORQUE
CHECKNlSFEBDThe inspection procedure for the tie rod end ball joint starting
torque is the same as for the manual steering system. (Refer to
P.19-8.)

STEERING WHEEL CENTERINGNlSFIYAFCenter the steering wheel in the same way as the manual
steering. (Refer to P.19-8.1
STATIONARY STEERING EFFORT CHECKNlSFFAI
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 rpm., there must be a return to
the standard idling rpm.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 fluctuationof the required steering force.
Standard value:
Steering effort37
N (8 lbs.) or less
Fluctuation allowance6 N (1.3 Iljs.)‘or less:...
STEERING WHEEL RETURN TO CENTER CHE$$$aETo 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 steeringforce 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 thewheel 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 CHECKNlSFliAl
1.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
pullev contact surface, and for scars or scratches onthe
pulley.2.
Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value: 6-9 mm
1.26.35 in.)
3. If there is a deviation from the standard value range, make
an adjustment of the belt tension by following the procedures
described below.
(1) Loosen bolts A, B and C (for holding the oil pump).
(2) Place a bar or similar object against the body of the oil
pump, and, while manually providing the suitable
amount of tension, adjust the amount of
flexion of the
belt.
(3) Tighten bolts A, B and C (for holding the oil pump).
(4) Check the amount of flexion of the belt; readjust if
necessary.
CautionThe check should be made after turning the engine
one time or more in the regular direction of rotation (tothe
dght).
FLUID LEVEL CHECKNlSFIAI
1.Park the vehicle on a flat, level surface, startthe engine, andthen turn the steering wheel several times to raise the
temperature of the fluid to approximately
50-60°C
(122-140°F).2. With the engine running, turn the wheel all the way to the
left and right several times.3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTNlSFJAJ
1.Raise the front wheels on a jack, and then support them with
rigid racks.2. Disconnect the return hose connection.
3.Connect a vinyl hose to the return hose, and drain the oil into
a container.
