5. VALVE SEAT
Assemble the valve, and measure the amount that the
valve protrudes from the valve shaft end between the
spring seat surfaces when the valve is pressed against
the valve seat. Replace the valve seat if the protrusion
amount exceeds the limit value.
Standard value:
Intake 49.20 mm
Exhaust 48.40 mm
Limit value:
Intake 49.70 mm
Exhaust 48.90 mm
Valve Seat Correction
1. Before correcting the valve seat, inspect the clearance
between the valve guide and valve, and replace the valve
guide if necessary.
2. Correct so that the seat width and seat angle are at the
specified shape.
3. After correcting, apply wrapping compound, and fit the
valve and valve seat together.
Valve Seat Replacement
1. Grind off the valve seat to be replaced from the inside
to reduce the thickness and then remove the valve seat.
2. Machine the valve seat hole on the cylinder head to match
the diameter of the oversized valve seat into which it
is to be pressed in.
Intake valve seat hole diameter:
0.3 O.S. 35.30 - 35.33 mm
0.6 O.S. 35.60 - 35.63 mm
Exhaust valve seat hole diameter:
0.3 O.S. 33.30 - 33.33 mm
0.6 O.S. 33.60 - 33.63 mm
3. When pressing in the valve seat, cool the valve seat
with liquid nitrogen, and make sure that the inner diameter
of the cylinder head is not galled.
4. Refer to the “Valve Seat Correction” procedures, and
machine the valve seat.Valve shaft end

Limit value: 0.1 mm

ENGINE OVERHAUL -Crankshaft and Cylinder Block11B-68
INSPECTION
1. CRANKSHAFT OIL CLEARANCE (PLASTIC GAUGE
METHOD)
The oil clearance can be measured easily by using the
“plastic gauge”.
Use the following steps to use the “plastic gauge”.
(1) Wipe off all oil from the crankshaft’s outer diameter
and bearing’s inner diameter.
(2) Assemble the crankshaft.
(3) Set a plastic gauge as long as the bearing width
on the journal shaft so that straightly aligned with
the shaft centre.
(4) Carefully install the beam bearing cap, and tighten
the bolt at the specified torque 25±2N•m+90_
to 100_.
(5) Remove the bolt, and carefully remove the beam
bearing cap.
(6) Measure the width of the crushed plastic gauge (at
the section crushed the most) with the scale printed
on the plastic gauge bag.
Standard value: 0.03 - 0.04 mm
Limit value: 0.1 mm
2. CYLINDER BLOCK
(1) Visually check for the presence of scratches, rusting,
or corrosion, and using flaw detection agent, etc.,
check for cracks. If any faults are found, repair or
replace the part.
(2) Using a straight edge and thickness gauge, measure
the flatness of the cylinder block’s upper surface.
Make sure that no gasket pieces, etc., are adhered
to the upper surface of the cylinder block when
measuring.
Standard value: 0.05 mm
Limit value: 0.1 mm
(3) Check for the presence of scratches or seizure on
the cylinder wall. If any faults are found, repair (over
size) or replace the part.
(4) Using a cylinder gauge, measure the inner diameter
and cylindricity of the cylinder. If greatly worn, repair
the cylinder to the over size, and replace the piston
ring.
Standard value: 85.0 mm
Cylindricity: 0.01 mm

REMOVAL SERVICE POINT
AA"SCREWS REMOVAL
1. Check out the alignment marks.
2. Loosen a uniform amount little by little the screws securing
differential case A to B.
3. Separate differential case B from differential case A and
remove their components.
Keep the removed spring plates, friction plates, and friction
discs organized in the order of removal and for right and
left use.
INSTALLATION SERVICE POINTS
"AADIFFERENTIAL CASE B INSTALLATION
Before starting the assembly procedure, perform the following
steps to adjust dimensional differences (clutch plate friction
force) in the axial direction of the components inside the
differential case and axial clearance of the differential side
gear.
1. Place friction discs (two each) and friction plates (three
each) one on top of another as illustrated and, using
a micrometer, measure the thickness of each of the right
and left assemblies. Select different discs and plates so
that the difference between the right and left assemblies
falls within the specified range.
Standard value: 0 – 0.05 mm
NOTE
If a new part is used, note that the friction disc comes
in two thicknesses: 1.6 mm and 1.7 mm.
2. Measure the thickness of each of the right and left spring
plates.
3. Assemble the pressure ring internal parts (pinion shaft
and pressure ring), friction plates, and friction discs and,
using a micrometer, measure the overall width.
NOTE
When taking measurements, press the assembly from
both sides so that the pinion shaft makes a positive contact
with the groove in the pressure ring.
4. Find value (A) which is the thickness measured in step
(3) added to the thickness of two spring plates.

3. See that the crimped width (A) meets the standard value.
Standard value (A): 2.4-2.8 mm

Readjust the dimension (W) of step (1) to the value
calculated by the following equation, and repeat step
(2).
W = 5.5 mm-A [Example: If (A) is 2.9 mm, (W)
is 2.6 mm.]

Remove the bellows band, readjust the dimension
(W) of step (1) to the value calculated by the following
equation, and use a new bellows band to repeat steps
(2) to (3).
W = 5.5 mm-A [Example: If (A) is 2.3 mm, (W)
is 3.2 mm.]
"NATIE ROD END/LOCKING NUT INSTALLATION
