STEERING WHEEL FREE PLAY CHECK
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 or less
3. When 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
towards steering wheel circumference and check play.
Standard value: 0 - 10 mm
5. If the play exceeds the standard value, remove steering
gear box and check total pinion torque. (Refer to
P.37A-17.)
STEERING ANGLE CHECK
1. Locate front wheels on turning radius gauge and measure
steering angle.
Standard value:
Inner wheel31_45’±1_30’
Outer wheel27_15’
2. When the angle is not within the standard value, the
toe-in is probably incorrect. Adjust the toe-in.
Standard value: 0±2mm
Adjust the toe-in by undoing the clip and lock nut, and
turning the left and right tie rod turnbuckles by the same
amount (in opposite directions).
3. Recheck the steering angle.
TIE ROD END BALL JOINT TURNING TORQUE
CHECK
1. Disconnect tie rod and knuckle with special tool.
Caution
(1) Loosen the nut of the special tool, but do not
remove it. If it is removed, the ball joint thread
may be damaged.
(2) Tie the special tool with a cord so as not to fall
off.

2. Move ball joint stud several times and install nut on stud.
Measure ball joint turning torque with special tool.
Standard value: 1.0 - 3.0 N·m
3. When the turning torque exceeds the standard value,
replace tie rod end.
4. When the turning torque is under the standard value,
check ball joint for end play or ratcheting. If none of these,
the joint is still serviceable.
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 r/min.
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 0.9 turns).
Also check to be sure that there is no significant fluctuation
of the required steering force.
Standard value:
Steering effort32 N or less
Fluctuation allowance6.0 N or less
4. If the standard values are not met, check and adjust
the related parts.
CHECKING STEERING WHEEL RETURN TO
CENTRE
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 not difference
in the steering force required and the wheel return between
left and right turns.
2. At a speed of 35 km/h, 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 be satisfactory.
NOTE
There will be a momentary feeling or “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.)
DRIVE BELT TENSION CHECK

REFRIGERANT LEAK REPAIR
LOST CHARGE
If the system has lost all charge due to a leak:
1. Evacuate the system. (See procedure.)
2. Charge the system with approximately one
pound of refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
6. Replace receiver drier.
Caution
Replacement filter-drier units must be
sealed while in storage. The drier used in
these units will saturate water quickly upon
exposure to the atmosphere. When
installing a drier, have all tools and supplies
ready for quick reassembly to avoid keeping
the system open any longer than necessary.
7. Evacuate and charge system.
LOW CHARGE
If the system has not lost all of its refrigerant charge;
locate and repair all leaks. If it is necessary to
increase the system pressure to find the leak
(because of an especially low charge) add
refrigerant. If it is possible to repair the leak without
discharging the refrigerant system, use the
procedure for correcting low refrigerant level.HANDLING TUBING AND FITTINGS
Kinks in the refrigerant tubing or sharp bends in
the refrigerant hose lines will greatly reduce the
capacity of the entire system. High pressures are
produced in the system when it is operating.
Extreme care must be exercised to make sure that
all connections are pressure tight. Dirt and moisture
can enter the system when it is opened for repair
or replacement of lines or components. The
following precautions must be observed. The
system must be completely discharged before
opening any fitting of connection in the refrigeration
system. Open fittings with caution even after the
system has been discharged. If any pressure is
noticed as a fitting is loosened, allow trapped
pressure to bleed off very slowly.
Never attempt to rebend formed lines to fit. Use
the correct line for the installation you are servicing.
A good rule for the flexible hose lines is keep the
radius of all bends at least 10 times the diameter
of the hose.
Sharper bends will reduce the flow of refrigerant.
The flexible hose lines should be routed so that
they are at least 80 mm from the exhaust manifold.
It is good practice to inspect all flexible hose lines
at least once a year to make sure they are in good
condition and properly routed.
Unified plumbing connections with O-rings, these
O-rings are not reusable.
COMPRESSOR NOISE
You must first know the conditions when the noise
occurs. These conditions are: weather, vehicle
speed, in gear or neutral, engine temperature or
any other special conditions.
Noises that develop during A/C operation can often
be misleading. For example: what sounds like a
failed front bearing or connecting rod, may be
caused by loose bolts, nuts, mounting brackets,
or a loose clutch assembly. Verify accessory drive
belt tension (power steering or alternator).
Improper accessory drive belt tension can cause
a misleading noise when the compressor is
engaged and little or no noise when the compressor
is disengaged.
Drive belts are speed-sensitive. That is, at different
engine speeds, and depending upon belt tension,
belts can develop unusual noises that are often
mistaken for mechanical problems within the
compressor.ADJUSTMENT
1. Select a quiet area for testing. Duplicate
conditions as much as possible. Switch
compressor on and off several times to clearly
identify compressor noise. To duplicate high
ambient conditions (high head pressure),
restrict air flow through condenser. Install
manifold gauge set to make sure discharge
pressure doesn’t exceed 2,070 kPa.
2. Tighten all compressor mounting bolts, clutch
mounting bolt, and compressor drive belt.
Check to assure clutch coil is tight (no rotation
or wobble).
3. Check refrigerant hoses for rubbing or
interference that can cause unusual noises.
4. Check refrigerant charge. (See “Charging
System”.)
5. Recheck compressor noise as in Step 1.
6. If noise still exists, loosen compressor mounting
bolts and retorque. Repeat Step 1.
7. If noise continues, replace compressor and
repeat Step 1.
