16. SET NO.1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley and align its groove with timing
mark º0º of the No.1 timing belt cover.
(b) Check that the timing marks of the camshaft timing pul-
leys and timing belt rear plates are aligned.
If not, turn the crankshaft 1 revolution (360°).
(c) Turn the crankshaft pulley approx. 50° clockwise, and
align the timing mark of the crankshaft pulley with the cen-
ters of the crankshaft pulley bolt and the No.2 timing belt
idler pulley bolt.
NOTICE:
If the timing belt is disengaged, having the crankshaft
pulley at the wrong angle can cause the piston head and
valve head to come into contact with each other when you
remove the camshaft timing pulley (step 15), causing dam-
age. So always set the crankshaft pulley at the correct
angle.
(d) Remove the crankshaft pulley bolt.
NOTICE:
Do not turn the crankshaft pulley.
17. REMOVE TIMING BELT TENSIONER
HINT:

When re±using the timing belt:
If the installation marks have disappeared, before remove
the timing belt, place 2 new installation marks on the tim-
ing belt to match the timing marks of the camshaft timing
pulleys.

When replacing the timing belt tensioner only:
To avoid meshing of the timing pulley and timing belt, se-
cure one of them with string. And place matchmarks on
the timing belt and RH camshaft timing pulley.
Alternately loosen the 2 bolts, and remove them, the belt ten-
sioner and dust boot.
18. DISCONNECT TIMING BELT FROM CAMSHAFT TIM-
ING PULLEYS
(a) Hold the camshaft timing pulley with SST, and loosen the
tension spring between the LH and RH camshaft timing
pulleys by slightly turning the LH camshaft timing pulley
clockwise.
SST 09960±10010 (09962±01000, 09963±01000)
HINT:
Set the SST so that the claw comes in contact with the camshaft
timing pulley bolt, and tighten the lock nut of the SST.
(b) Disconnect the timing belt from the camshaft timing pul-
leys.
19. REMOVE CAMSHAFT TIMING PULLEYS
(a) Hold the camshaft timing pulley with SST, loosen the 4
bolts of the timing pulley.
SST 09960±10010 (09962±01000, 09963±01000)
(b) Remove the 2 timing pulleys.
20. REMOVE GENERATOR (See page CH±7)
21. REMOVE DRIVE BELT TENSIONER

12. INSTALL RH CAMSHAFT TIMING PULLEY
(a) Align the camshaft timing tube knock pin with the knock
pin groove of the timing pulley.
(b) Temporarily install the 4 bolts of the camshaft timing
pulley.
(c) Hold the camshaft timing pulley with SST, and tighten the
pulley bolt.

13. CONNECT TIMING BELT TO LH CAMSHAFT TIMING
PULLEY
(a) Remove any oil or water on the timing pulley, and keep it
clean.
NOTICE:
Only wipe the pulleys; do not use any cleansing agent.
(b) Using SST, turn the timing pulley. Align the installation
mark on the timing belt with the timing mark of the timing
pulley, and hang the timing belt on the timing pulley.
SST 09960±10010 (09962±01000, 09963±01000)
(c) Using SST, turn the LH camshaft timing pulley counter-
clockwise until there is tension between the crankshaft
timing pulley and LH camshaft timing pulley.

14. CONNECT TIMING BELT TO RH CAMSHAFT TIMING
PULLEY
(a) Remove any oil or water on the camshaft timing pulley
and water pump pulley, and keep them clean.
NOTICE:
Only wipe the pulleys; do not use any cleansing agent.
(b) Using SST, turn the timing pulley. Align the installation
mark on the timing belt with the timing mark of the timing
pulley, and hang the timing belt on the timing pulley.
