16. Remove collared O-ring from front timing chain case (left and
right side).
17. Remove rocker covers (right and left banks). Refer to EM-51, "
Component".
NOTE:
When only timing chain (primary) is removed, rocker cover does not need to be removed.
18. Obtain No. 1 cylinder at TDC of its compression stroke as follows: NOTE:
When timing chain is not removed/installed, this step is not required.
a. Rotate crankshaft pulley clockwise to align timing mark (grooved line without color) with timing indicator.
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 alignas 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-65,
"Removal and Installation".
19. Remove crankshaft pulley as follows:
a. Remove rear cover plate (2WD models) or star ter motor (AWD models) and set ring gear stopper (SST).
Refer to EM-30, "
Component (2WD Models)" (2WD models) or SC-8, "System Description" (AWD mod-
els).
b. Loosen crankshaft pulley bolt and locate bolt seating surface as 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.
