6. Install the camshaft sprocket (INT) to the camshaft (INT) with the
following procedure.
a. Align the matching mark (A) put according to step “4”. Securely
align the knock pin and the pin hole, and then install them.
b. Temporarily tighten the bolt on the front side of camshaft (INT)
(1).
7. Put a thick shop cloth (B) to the lower surface, and then set the
tools to the bolt camshaft (INT) (1).
8. Tighten the mounting bolt.
CAUTION:
Hold the camshaft hexagonal part (A), and then secure the
camshaft.
9. Return the camshaft (INT) to the cylinder head carefully.
10. Install the camshaft (EXH) to the camshaft sprocket (EXH) (2)
while aligning the matching make (marked when timing chain is
removed) (A) and the matching mark (stamp) (B) of camshaft
sprocket (EXH).
If the positions of knock pin and pin groove are not aligned,
move the camshaft (EXH) slightly to correct these positions.

14. Install timing chain with the following procedure.
Install by aligning matching marks on each sprocket and tim-
ing chain.
If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
Check matching mark position of each sprocket and tim-
ing chain again after installing the timing chain, keep
matching marks aligned by holding them with a hand.
To avoid skipped teeth, never rotate crankshaft and cam-
shaft until front cover is installed.
15. Install timing chain tension guide (2) and timing chain slack
guide (1).
16. Install chain tensioner (1).
Fix the plunger at the most compressed position using a stop-
per pin (A), and then install it.
Securely pull out the stopper pin after installing the chain ten-
sioner.
17. Check matching mark position of timing chain and each sprocket again.

18. Pull out the stopper pin (A), and then apply the tension to the
timing chain by rotating the crankshaft pulley clockwise slightly.
19. Return the camshaft sprocket (INT) in the most retarded position with the following procedure.
a. Remove the stopper pin (A) from the camshaft sprocket (INT).
b. Turn the crankshaft slowly clockwise and return the camshaft sprocket (INT) to the most retarded angle
position.
When first turning the crankshaft the camshaft sprocket (INT)
will turn. Once it is turned more, and the vane (camshaft) also
turns, then it has reached the most retarded angle position.
The most retarded angle position can be checked by seeing if
the stopper pin groove (A) is shifted clockwise.
After spinning the crankshaft slightly in the counterclockwise
direction, you can make sure the lock pin has joined by seeing
if the vane (camshaft) and the sprocket move together.
20. Install the front oil seal to the front cover. Refer to EM-78, "

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.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
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 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
main bearing and/or connecting rod bearing.
CRANKSHAFT RUNOUT
Place a V-block on a precise flat table to support the journals on
the both end of crankshaft.
Place a dial indicator (A) straight up on the No. 3 journal.
While rotating crankshaft, read the movement of the pointer on the
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 cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)
If the clearance exceeds the limit, select proper connecting rod
bearing according to connecting rod big end diameter and crank-
shaft pin journal diameter to obtain the specified bearing oil clear-
ance. Refer to EM-117, "
Connecting Rod Bearing".
Method of Using Plastigage
Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely.
Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
CAUTION:Standard : Refer to EM-127, "
