3) Rear wheel cylinder fluid pressure measurement
Step on the brake pedal until the fluid pressure of the front wheel cylinder gets to 9.8Mpa (100kg/cm
2), and
check the rear wheel cylinder fluid pressure. (Read the
value of the front wheel cylinder fluid pressure 2
seconds after the measurement. W hen measuring the
LSPV fluid pressure, keep the brake pedal pressed
down without stepping it down twice or releasing it.)

2. Oil Pressure Adjustment
1) LSPV spring length adjustment
Loosen the adjust nut of the LSPV spring joint, and adjust the length of the LSPV spring.
W hen the oil pressure is insufficient, turn the adjust nut clockwise to extend the span “A”. W hen the oil pressure
is too high, turn the adjust nut counterclockwise to
reduce the span “A”.


2) After adjustment, tighten the lock nut securely.

CONNECTING ROD
Connecting Rod Alignment
Use a connecting rod aligner to measure the distortion and the
parallelism between the connecting rod big end hole and the
connecting rod small end hole.
If either the measured distortion or parallelism exceed the
specified limit, the connecting rod must be replaced.

Connecting Rod Alignment Per Length of 100 mm (3.94 in)
mm (in)
Standard Limit
Distortion 0.08 (0.003) or Less 0.20 (0.008)
Parallelism 0.05 (0.002) or Less 0.15 (0.006)


Connecting Rod Side Face Clearance
1. Install the connecting rod to the crankpin.
2. Use a feeler gauge to measure the clearance between the connecting rod big end side face and the crankpin side
face.
If the measured value exceeds the specified limit, the
connecting rod must be replaced.

Piston Pin and Connecting Rod Small End
Bushing Clearance
Use a caliper calibrator and a dial indicator to measure the
piston pin and connecting rod small end bushing clearance.
If the clearance between the piston pin and the connecting rod
small end bushing exceeds the specified limit, replace the
piston pin and/or the connecting rod.

FILLER NECK
Removal
1. Remove the fuel tank.
NOTE: Refer to "Fuel Tank" in this section.
2. Put a marking the following point as the filler neck assembl
y
is restored.
• Each joint area of the hose (to restore axial direction and
insertion length of the hose)
• Each fasten area of the clamp (to restore axial direction
and position of the clamp)
• Each bolt in the clamp (to restore fasten length of bolt in
the clamp)
• The band clip (to restore position and fasten length o
f
the band clip)
NOTE: Cover end of each hose and pipe to prevent any dust
entering.










Installation
1. Align each marking and restore the following point.
• Each joint area of the hose (Restore axial direction and
insertion length of the hose)
• Each fasten area of the clamp (Restore axial direction
and position of the clamp)
• Each bolt in the clamp (Restore fasten length of bolt in
the clamp)

4. Install the pin to the dial gauge.
Note:
The lengths of the pins do not include the threaded portions.
Pin (L=100 mm): 157892-5200 (Bosch AS)
Dial gauge: 157954-3800 (Bosch AS)
185317-0150 (ISUZU)

5. Secure the dial gauge to the nozzle holder using the nut so that the pin contacts the tip of the first spring
seat.

CAUTION:
• Secure the dial gauge so that a stroke of 2 mm can
be measured.
• Do not over-tighten the nut as the dial gauge shaft
may jam. (Confirm from the dial gauge that the
shaft moves smoothly.)

6. Set the nozzle holder to the nozzle tester and put needle to zero on the dial gauge.
7. Operate the nozzle tester to bleed any air from inside the retaining nut and to confirm that no fuel leaks.

BRUSH
Measure the length of the brush. If abrasion has reduced
the brush length to less than 6.5 mm, the brush must be
replaced with a new one.
A wear line is inscribed in the brush. If the line is not
visible, the brush must be replaced.

BRUSH AND BRUSH HOLDER
1. Use a vernier caliper to measure the brush length (four
brushes).
Replace the brushes as a set if one or more of the
brush lengths is less than the specified limit.

2. Use a circuit tester to check the brush holder
insulation.
Touch one probe to the holder plate and the other
probe to the positive brush holder.
There should be no continuity.





3. Inspect the brushes for excessive wear. If the negative brushes have excessive wear, the
entire brush holder assembly must be replaced.
If the positive brushes have excessive wear, the entire
yoke must be replaced.

OVERRUNNING CLUTCH
1. Inspect the overrunning clutch gear teeth for excessive wear and damage.
Replace the overrunning clutch if necessary.
2. Rotate the pinion clockwise. It should turn smoothly.
3. Try to rotate the pinion in the opposite direction. The pinion should lock.
