a.
Remove starter motor and set ring gear stopper (SST) as shown
in the figure. Refer to
.
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.

a.
Loosen mounting bolts in reverse order as shown in the figure.
b.
Insert suitable tool into the notch at the top of the front timing
chain case as shown (1).
c.
Pry off case by moving the tool as shown (2).
●
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.
24. Remove O-rings from rear timing chain case.
25. 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.
26. 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.

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:
Even if plunger is fully expanded, it is not dropped from the body
of timing chain tensioner (primary).
c.
Remove upper mounting bolt, and then remove timing chain ten-
sioner (primary).
28. Remove internal chain guide, tension guide and slack guide.
NOTE:
Tension guide can be removed after removing timing chain (pri-
mary).
29. 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.
30. 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)
is required.]

b.
Remove intake and exhaust camshaft sprocket bolts.
●
Secure the hexagonal portion of camshaft using wrench to
loosen mounting bolts.
CAUTION:
Do not loosen mounting bolts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
c.
Remove timing chain (secondary) together with camshaft sprockets.
●
Turn camshaft slightly to secure slackness of timing chain on timing chain tensioner (secondary) side.
●
Insert 0.5 mm (0.020 in)-thick metal or resin plate between
timing chain and timing chain tensioner plunger (guide).
Remove timing chain (secondary) together with camshaft
sprockets with timing chain loose from guide groove.
CAUTION:
Be careful of plunger coming-off when removing timing
chain (secondary). This is because plunger of timing
chain tensioner (secondary) moves during operation,
leading to coming-off of fixed stopper pin.
NOTE:
Camshaft sprocket (INT) is two-for-one structure of primary
and secondary sprockets.
●
When handling camshaft sprocket (INT), be careful of the fol-
lowing caution:
CAUTION:
●
Handle carefully to avoid any shock to camshaft
sprocket.
●
Do not disassemble. (Do not loosen bolts “A” as
shown in the figure).
31. Remove water pump. Refer to
32. Remove rear timing chain case as follows:
a.
Loosen and remove mounting bolts in reverse order as shown in
the figure.
b.
