CYLINDER BLOCK
Revision: 2005 July 2005 FX

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.

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.
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove carrier cover mounting bolts.
3. Remove carrier cover to insert the seal cutter between gear car- rier and carrier cover.
CAUTION:

Be careful not to damage the mating surface.

Do not insert flat-bladed screwdriver, this way damage
the mating surface.

InspectionAES000OP
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):
