Revision: 2006 January2006 M35/M45
CRANKSHAFT PIN JOURNAL DIAMETER
Measure the outer diameter of crankshaft pin journal with a
micrometer.
If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-146,
"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 a 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-147, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-146, "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 a dial indicator straight up on the No. 3 journal.
While rotating crankshaft, read the movement of the pointer on a
dial indicator. (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 cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-128, "
ASSEMBLY" for the tightening proce-
dure.
Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Oil clearance) = (Connecting rod bearing inner diameter) – (Crank-
shaft pin journal diameter)Standard : 51.956 - 51.974 mm (2.0455 - 2.0462 in) dia.

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).

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.
