3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:

Do not loosen mounting bolts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.

After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets.

Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.

Equally loosen camshaft brackets and bolts in several steps in
reverse order as shown in the figure.

Lightly tapping with plastic hammer, remove camshaft bracket
(No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove adjusting shim and valve lifter if necessary.

Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft 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. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.

Camshaft End Play

Install dial indicator in thrust direction on front end of camshaft.
Measure the end play of dial indicator when camshaft is moved
forward/backward (in direction to axis).

Measure the following parts if out of the limit.
–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.
Valve Lifter and Adjusting Shim
Check if surface of valve lifter and adjusting shim has any wear or
cracks.

If anything above is found, replace valve lifter.

When replacing adjusting shim, refer to EM-222, "ADJUST-
MENT" .
Standard:
0.115 - 0.188 mm (0.0045 - 0.0074 in)
PBIC2446E
Standard : 30.500 - 30.548 mm (1.2008 - 1.2027 in)

If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Refer to EM-
270, "MAIN BEARING OIL CLEARANCE" .
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-269,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

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 the dimensions
between “X” and “Y” at “A” and “B”.

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

If the measured value 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 the main bearing and/or connecting rod bearing. Refer to EM-270, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-269, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block on precise flat table, and support the journals on
the both end of crankshaft.

Place dial indicator straight up on the No. 3 journal.

While rotating crankshaft, read the movement of the pointer on
dial indicator. (Total indicator reading)

If it exceeds the limit, replace crankshaft. Standard : 63.940 - 63.964 mm (2.5173 - 2.5183 in) dia.
Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.

Limit: Out-of-round (Difference between “X” and “Y”) : 0.015 mm (0.0006 in)
Taper (Difference between “A” and “B”) : 0.010 mm (0.0004 in)

c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Side Shaft Assembly
1. Hold extension tube retainer with puller, then press out side shaft using a press.
2. Remove side shaft oil seal from extension tube retainer with a flat- blade screwdriver.
3. Remove side shaft bearing from extension tube retainer.
4. Remove O-ring from extension tube retainer.
5. Remove dust sealed from side shaft.

ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
a. Remove tire from aluminum wheel and mount on a tire balance machine.
b. Set dial indicator as shown in the figure.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance machine.
b. Set two dial indicators as shown in the figure.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega- tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel. Wheel runout (Dial indicator value):
