CAMSHAFT JOURNAL OIL CLEARANCE

(Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)

If out of the standard, replace either or both camshaft and cylinder head.
NOTE:
Camshaft bracket cannot be replaced as a single part, because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play
1. Install camshaft in cylinder head. Refer to EM-47, "INSTALLATION" for the tightening procedure.
2. Install dial indicator in thrust direction on front end of camshaft.
Read the end play of dial indicator when camshaft is moved for-
ward/backward (in direction to axis).

Measure the following parts if out of the standard.
–Dimension “A” for camshaft No. 1 journal
–Dimension “B” for cylinder head No. 1 journal bearing

Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journal of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.
2. Measure the camshaft sprocket runout with dial indicator. (Total
indicator reading)

If it exceeds the limit, replace camshaft sprocket.Standard : 0.045 - 0.086 mm (0.0018 - 0.0034 in)

CRANKSHAFT PIN JOURNAL DIAMETER

Measure the outer diameter of crankshaft pin journal with micrometer.

If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
Refer to EM-105, "
CONNECTING ROD BEARING OIL CLEARANCE" .
OUT-OF-ROUND AND TAPER OF CRANKSHAFT

Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with micrometer.

Out-of-round is indicated by the difference in dimensions
between “X” and “Y” at “A” and “B”.

Taper is indicated by the difference in dimension between “A”
and “B” at “X” and “Y”.

If the measured valve exceeds the limit, correct or replace crankshaft.

If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
select main bearing and/or connecting rod bearing. Refer to EM-106, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-105, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

On-Vehicle Inspection and ServiceBGS0003S
CHECKING CONDITION OF INSTALLATION

Check installation conditions of steering gear assembly, front suspension assembly, axle and steering col-
umn assembly.

Check if movement exists when steering wheel is moved up and down, to the left and right and to the axial
direction.

Check steering gear assembly mounting nut and bolts for looseness. Refer to PS-17, "COMPONENTS" .
CHECKING STEERING WHEEL PLAY

Turn steering wheel so that front wheels come to the straight-ahead position. Start engine and lightly turn
steering wheel to the left and right until front wheels start to move. Measure steering wheel movement on
the outer circumference.

When the measurement value is outside the standard value, check backlash for each joint of steering col-
umn assembly and installation condition of power steering gear assembly.
CHECKING NEUTRAL POSITION STEERING WHEEL

Make sure that steering gear assembly, steering column and steering wheel are installed in the correct
position.

Perform neutral position inspection after wheel alignment. Refer to FSU-5, "Wheel Alignment Inspection" .

Set vehicle to the straight-ahead position and confirm steering wheel is in the neutral position.

Loosen outer socket lock nut and turn inner socket to left and right equally to make fine adjustments if
steering wheel is not in the neutral position.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80°C (122 to 176°F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-29,
"CHECKING RELIEF OIL PRESSURE" .
a. Disconnect lower shaft and steering knuckle from steering gear assembly. Refer to FAX-5, "
COMPO-
NENT" , PS-12, "COMPONENTS" .
b. Start and run engine at idle to make sure steering fluid has reached normal operating temperature.Steering wheel axial end play : 0 mm (0 in)
