crankshaft pulley through.
CAUTION:
Do not put suitable puller tab on crankshaft pulley periph-
ery, as this will damage internal damper.

NOTE:
Tension guide can be removed after removing timing chain (pri-
mary).
32. 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.
33. 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
EM-84, "
CAMSHAFT" . [Removing camshaft bracket (No. 1)
is required.]
b. Remove camshaft sprocket (INT and EXH) mounting bolts.
Secure the hexagonal portion of camshaft using a wrench to
loosen mounting bolts.
CAUTION:
Do not loosen the 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).
34. Remove rear timing chain case as follows:
a. Loosen and remove mounting bolts in reverse order as shown in
the figure.
b. Cut liquid gasket using the seal cutter [SST: KV10111100
(J37228)] and remove rear timing chain case.
CAUTION:
Do not remove plate metal cover of oil passage.
After removal, handle rear timing chain case carefully so
it does not tilt, cant, or warp under a load.
