CRANKSHAFT PIN JOURNAL DIAMETER

Measure outer diameter of crankshaft pin journal with microme-
ter.

If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-142,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

Using a micrometer, measure the dimensions at “4” different
points shown in the figure on each journal and pin.

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 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-143, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-142, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

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

Place a dial gauge straight up on No. 3 journal.

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

If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation

Install connecting rod bearings to connecting rod and connect-
ing rod bearing cap, and tighten connecting rod bolts to the
specified torque. Using a inside micrometer measure the inner
diameter of connecting rod bearing. Refer to EM-126, "
ASSEM-
BLY" for the tightening procedure.
(Oil clearance) = (Connecting rod bearing inner diameter) – (Crank-
shaft pin diameter)Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.

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 No. 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
three locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure cam-
shaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure camshaft cam height with micrometer.
2. If wear is beyond the limit, replace camshaft.

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

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 No. 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 three locations.
2. Measure camshaft sprocket runout with dial indicator. (Total indi-
cator 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-217, "ADJUST-
MENT" .
