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 standard.
–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-225, "ADJUST-
MENT" . Standard:
0.115 - 0.188 mm (0.0045 - 0.0074 in)

CYLINDER BLOCK
Revision: 2006 January2006 M35/M45
If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Refer to EM-
274, "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-273,
"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-274, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-273, "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.

5. Remove stopper ring with a flat-bladed screwdriver, and pull out
housing.
6. Put matching marks on ball cage, steel ball and Inner race assembly and shaft.
CAUTION:
Use paint or similar substance for matching marks. Do not scratch the surface.
7. Remove snap ring, then remove ball cage, steel ball and Inner
race assembly from shaft.
8. Remove boot from shaft.
9. Remove old grease on housing with paper towels.
Wheel Side
1. Remove dust shield from drive shaft.
2. Secure shaft in a vise.
CAUTION:
Protect shaft when securing in a vise using aluminum or copper plates.
3. Remove boot bands. Then remove boot from joint sub-assembly.
4. Screw a drive shaft puller 30 mm (1.18 in) or more into threaded
part of joint sub-assembly. Pull joint sub-assembly out of shaft.
CAUTION:
If joint sub-assembly cannot be removed after five or
more unsuccessful attempts, replace shaft and joint sub
assembly as a set.
Align sliding hammer and drive shaft and remove them
by pulling directory.

bly with paper towels.
INSPECTION AFTER DISASSEMBLY
Shaft
Replace shaft if there is any runout, cracking, or other damage.
Joint Sub-Assembly (Wheel Side)
Check the following:
Joint sub-assembly for rough rotation and excessive axial looseness.
The inside of the joint sub-assembly for entry of foreign material.
Joint sub-assembly for compression scars, cracks, and fractures inside of joint sub-assembly.

REAR FINAL DRIVE ASSEMBLY
Revision: 2006 January2006 M35/M45
Companion Flange Runout
1. Fit a test indicator to the inner side of companion flange (socket
diameter).
2. Rotate companion flange to check for runout.
3. If the runout value is outside the runout limit, follow the proce-
dure below to adjust.
a. Check for runout while changing the phase between companion
flange and drive pinion by 90
step, and search for the position
where the runout is the minimum.
b. If the runout value is still outside of the limit after the phase has
been changed, possible cause will be an assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if necessary.
c. If the runout value is still outside of the limit after the check and repair, replace companion flange.
DISASSEMBLY
Differential Assembly
1. Drain gear oil, if necessary.
2. Remove side flange.
3. Remove rear cover mounting bolts.
4. Remove rear cover to insert the seal cutter between gear carrier
and rear cover.
CAUTION:
Be careful not to damage the mating surface.
Do not insert flat-bladed screwdriver, this way damage
the mating surface.
5. Using two 45 mm (1.77 in) spacers, mount carrier on the attach-
ment.
6. For proper reinstallation, paint matching marks on one side of
the bearing cap.
CAUTION:
For matching marks, use paint. Do not damage bearing
caps and gear carrier.
Bearing caps are line-board during manufacture. The
matching marks are used to reinstall them in their origi-
nal positions.Runout limit: 0.08 mm (0.0031 in)

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):
