2-12 PERIODIC MAINTENANCE
12. Remove the timing belt from the cam pulley first, then from
the timing pulley.
13. Install the timing belt on the timing pulley first, then the cam
pulley.
14. Make sure that either of the PUNCH marks on the cam pul-
ley aligns with the INDEX mark on the cylinder head block
when the PUNCH mark on the timing pulley aligns with the
INDEX mark on the cylinder block.
15. Install following parts.
• Stator base (See page 3-13.)
• Flywheel (See page 3-13.)
• Recoil starter (See page 5-8.)
• Side covers
• Spark plugs
16. Check wire routing. (See page 9-5 to 9-7.)
Do not rotate the crankshaft or the cam pulley before
installing the belt; the following must be checked:
• The PUNCH mark on the timing pulley aligns with the
INDEX mark on the cylinder block.
• Either of the PUNCH marks on the cam pulley aligns
with the INDEX mark on the cylinder head block.
If the timing pulley or the cam pulley is rotated with
the timing belt removed or installed but misaligned,
this may cause the valves to become bent.
If the alignment marks are not correctly matched,
loosen the valve adjusting lock nuts and the valve
adjusting screws fully to prevent valve damage.
Then align the marks correctly by rotating the cam
pulley clockwise.
Always keep the timing belt away from any grease and
oil.
The timing belt must be installed with the arrow mark
on the timing belt toward the direction of rotation.
