decompressor system.
TIMING CHAIN
Inspection
Distance between chain tensioner guide and end
of chain tensioner housing is a general information
about the valve train (chain) condition.
1. Timing gear
2. Chain tensioner guide
3. Chain tensioner plunger
A. Chain tensioner plunger protrusion
If protrusion exceeds service limit, replace timing
chain, camshaft timing gear, chain guide and chain
tensioner guide at the same time.
Check timing chain on camshaft timing gear for ex-
cessive radial play.
Check chain condition for wear and rollers condition.
1. Timing chain
If chain is excessively worn or damaged, replace it
as a set (camshaft timing gear and timing chain).
Removal
Remove:
– engine from vehicle
(refer to REMOVAL AND INSTALLATION)
– valve cover, chain tensioner and camshaft tim-
ing gear (refer to CYLINDER AND HEAD)
– magneto cover and rotor
(refer to MAGNETO SYSTEM)
– output shaft (refer to GEARBOX).
If the chain is not changed, note the operation di-
rection to reinstall it in the same way.
Installation
The installation is essentially the reverse of the re-
moval procedure but, pay attention to the follow-
ing details.
Ensure to perform proper valve timing. Lock crank-
shaft and camshaft at ignition TDC (refer to CYL-
INDER AND HEAD).
Install chain then, adjust chain tension (refer to
CYLINDER AND HEAD).
CAUTION:
Improper valve timing will damage
engine components.
