c. Shaft is engaged with intake side camshaft sprocket center hole
on inside. Pull straight out so as not to tilt until the joint is disen-
gaged.

The mating surface of magnet retarder may be fitted with the
exhaust side camshaft sprocket via the engine oil. Open valve
timing control cover carefully.

If the mating surface of magnet retarder is fitted with the cam-
shaft sprocket, open the cover within the range that the load is
not applied to the harness. And then, remove it so as to pre-
vent magnet retarder from dropping.
CAUTION:

Be careful not to damage magnet retarder.

When carrying valve timing control cover, face the magnet retarder side up to prevent the cover
from falling from magnet retarder.

Do not remove magnet retarder from valve timing control cover. (Disassembly prohibited parts)
18. Remove rocker covers (right and left banks). Refer to EM-40, "
ROCKER COVER" .
NOTE:
When only timing chain (primary) is removed, rocker cover does not need to be removed.
19. 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 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-60,
"INSTALLATION" .
20. Remove crankshaft pulley as follows:
a. Remove rear cover plate and set ring gear stopper [SST:
KV10118600 (J-48641)] (A) as shown in the figure.

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.
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.
21. Remove oil pan (lower). Refer to EM-26, "

2. Hammer dowel pins (right and left) into front timing chain case
up to a point close to taper in order to shorten protrusion length.
3. Install new front oil seal on the front timing chain case.

Apply new engine oil to both oil seal lip and dust seal lip.

Install it so that each seal lip is oriented as shown in the fig-
ure.

Using suitable drift [outer diameter: 60 mm (2.36 in)] (A),
press-fit oil seal until it becomes flush with front timing chain
case end face.

surface of magnet retarder (A) at several places and the circum-
ferential looseness (between dowel pins and dowel pin holes) by
twisting in the circumferential direction.
CAUTION:
Always perform this procedure when removing because the
gap between dowel pins and dowel pin holes may not be
caused on purpose.M10 bolts : 1, 2, 3, 4, 5, 6, 7
