a.
Loosen mounting bolts in reverse order as shown in the figure.
b.
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
19. Obtain No. 1 cylinder at TDC of its compression stroke as follows:
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.

Remove starter motor and set ring gear stopper (SST) as shown
in the figure. Refer to
b.
Loosen crankshaft pulley bolt and rotate 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.
21. Remove oil pans (upper and lower). Refer to

●
Use seal cutter [SST: KV10111100 (J37228)] to cut liquid gas-
ket for removal.
CAUTION:
●
Do not use screwdriver or something similar.
●
After removal, handle front timing chain case carefully so
it does not tilt, cant, or warp under a load.
23. Remove O-rings from rear timing chain case.
24. Remove water pump cover and chain tensioner cover from front timing chain case.
●
Use seal cutter [SST: KV10111100 (J37228)] to cut liquid gasket for removal.
25. Remove front oil seal from front timing chain case using suitable
tool.
●
Use screwdriver for removal.
CAUTION:
Be careful not to damage front timing chain case.
26. Remove timing chain tensioner (primary) as follows:
a.
Remove lower mounting bolt.
b.
Loosen upper mounting bolt slowly, and then turn timing chain
tensioner (primary) on the mounting bolt so that plunger is fully
expanded.

NOTE:
Tension guide can be removed after removing timing chain (pri-
mary).
28. Remove timing chain (primary) and crankshaft sprocket.
CAUTION:
After removing timing chain (primary), do not turn crankshaft and camshaft separately, or valves
will strike the piston heads.
29. Remove timing chain (secondary) and camshaft sprockets as follows:
a.
Attach suitable stopper pin to the right and left timing chain ten-
sioners (secondary).
NOTE:
●
Use approximately 0.5 mm (0.02 in) dia. hard metal pin as a
stopper pin.
●
For removal of timing chain tensioner (secondary), refer to
. [Removing camshaft bracket (No. 1)

b.
Remove intake and exhaust camshaft sprocket bolts.
●
Secure the hexagonal portion of camshaft using wrench to
