BRAKE DISC RUN-OUT CHECK AND
CORRECTION
1. Remove the brake assembly, and then hold it with wire.
2. Temporarily install the disc with the hub nut.
3. Place a dial gauge approximately 5 mm (0.2 inch) from the
outer circumference of the brake disc, and measure the
run-out of the disc.
Limit:
: 0.10 mm (0.0039 inch)
: 0.04 mm (0.0016 inch)
4. If the brake disc run-out exceeds the limit, correct it as
follows:
(1) Chalk phase marks on the wheel stud and the brake disc
as shown.
(2) Remove the brake disc. Then place a dial gauge as
shown, and measure the end play while moving the hub
in the axial direction.
Limit: 0.05 mm (0.002 inch)
(3) If the end play exceeds the limit, replace the hub
assembly.
(4) If the end play does not exceed the limit, dephase the
brake disc and secure it. Then recheck the brake disc
run-out.

BELT DEFLECTION CHECK
Apply approximately 98 N (22 lb) of force to the middle of the
drive belt between the pulleys (at the place indicated by the
arrow) and check that the amount of deflection is within the
standard value.
Standard value:
.if the tension or deflection is outside the standard value, adjust
by the following procedure.
1. Loosen the tensioner pulley lock nut.
2. Adjust the belt tension to the standard value by turning the
adjusting bolt. The tension will increase when turning the
adjusting bolt clockwise, and decrease when turning
counterclockwise.
3. Tighten the lock nut to the specified torque.
Tightening torque: 49
9 Nm (36 7 ft-lb)
4. Tighten the adjusting bolt.
Tightening torque: 5.0
1.0 Nm (44 9 in-lb)
Check after turning the crankshaft one or more rotations
clockwise.
5. Check the belt deflection amount and tension, and readjust
if necessary.

SYMPTOM CHARTM1261005700269
SYMPTOM PROCEDURES
INSPECTION PROCEDURE 1: Noise during Wheel Rotation
DIAGNOSIS
STEP 1. Check the wheel bearing end play.
(1) Remove the caliper assembly and suspend it with a wire.
(2) Remove the brake disc from the front hub.
(3) Attach a dial gauge as shown in the illustration, and then
measure the end play while moving the hub in the axial
direction.
Limit: 0.05 mm (0.002 inch)
Q: Is the wheel bearing end play within the limit?
YES : Go to step 2.
NO : Replace the part, then go to Step 5.
STEP 2. Check the drive shaft and inner shaft for bending.
Q: Is the drive shaft and inner shaft bent?
YES : Replace the part. Then go to Step 5.
NO : Go to step 3.
STEP 3. Check the center bearing for wear.
Q: Is the center bearing worn?
YES : Replace the bearing. Then go to Step 5.
NO : Go to step 4.
STEP4. Check the drive shaft assembly for wear or
damage.
Q: Is the drive shaft assembly worn or damaged?
YES : Replace the drive shaft assembly. Then go to Step 5.
NO : There is no action to be taken. SYMPTOM INSPECTION

NO : Go to Step 2.
STEP 2. Check the wheel bearing end play.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Check the bearing's end play. Place a dial gauge against
the hub surface; then move the hub in the axial direction
and check whether or not there is end play.
Limit: 0.05 mm (0.002 inch)
Q: Is the wheel bearing end play within the limit?
YES : Go to Step 3.
NO : Replace the rear hub assembly, then go to Step 4.
STEP 3. Check the rear hub rotary-sliding resistance.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Turn the hub a few times to seat the bearing.
(3) Wind a rope around the hub bolt and turn the hub by pulling
at a 90
angle with a spring balance. Measure to determine
whether or not the rotary-sliding resistance of the rear hub
is within the limit value.
Limit: 24 N (5.4 lbs)
Q: Is the rear hub rotary-sliding resistance within the limit?
YES : Go to Step 4.
NO : Replace the rear hub assembly, then go to Step 4 .
