FRONT TIMING CHAIN CASE

b. Make sure that intake and exhaust cam noses on No. 1 cylinder
(engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
NOTE:
When only timing chain (primary) is removed, rocker cover does
not need to be removed. To make sure that No. 1 cylinder is at
its compression TDC, remove front timing chain case first. Then
check mating marks on camshaft sprockets. Refer to EM-181,
"INSTALLATION" .
16. Remove crankshaft pulley as follows:
a. Fix crankshaft with pulley holder (SST).
b. Loosen crankshaft pulley bolt and locate bolt seating surface at
10 mm (0.39 in) from its original position.
CAUTION:
Do not remove crankshaft pulley bolt as it will be used as a
supporting point for suitable puller.
c. Place suitable puller tab on holes of crankshaft pulley, and pull
crankshaft pulley through.
CAUTION:
Do not put suitable puller tab on crankshaft pulley periph-
ery, as this will damage internal damper.
17. Remove oil pan (lower). Refer to EM-145, "
OIL PAN AND OIL STRAINER" .
18. Loosen two mounting bolts in front of oil pan (upper) in the
reverse order as shown in the figure.
19. Install oil pan (lower) temporarily.

Applying liquid gasket is unnecessary.
20. Support the oil pan (lower) bottom with jack.

Perform following operations with engine front side supported with jack.
CAUTION:
Put a piece of wood or something similar as the supporting surface, be careful not to damage oil
pan (lower).
21. Remove right and left intake valve timing control covers.

(engine front side of right bank) are located as shown in the fig-
ure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

Valve ClearanceBBS004W2
INSPECTION
In cases of removing/installing or replacing camshaft and valve-
related parts, or of unusual engine conditions due to changes in
valve clearance (found malfunctions during stating, idling or causing
noise), perform inspection as follows:
1. Remove rocker covers (right and left banks). Refer to EM-160, "
ROCKER COVER" .
2. Remove splash guard (RH).
3. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.

Rotate crankshaft pulley clockwise to align timing mark
(grooved line without color) with timing indicator.

Make sure that intake and exhaust cam noses on No. 1 cylin-
der (engine front side of right bank) are located as shown in
the figure.

If not, rotate crankshaft one revolution (360 degrees) and
align as shown in the figure.
