MACHINING OF FLYWHEEL
1 Flywheel
Machining of Flywheel
Notice
Flywheels which have scorch marks, scoring or cracks in
the clutch surface should be machined by grinding or
precision-turning. If the scores or cracks are severe than
permissible specifications, replace the flywheel.
lWhen machining the clutch surface ‘A’, the mounting
surface (B) for the clutch pressure plate should also be
machined in accordance with ‘A’ to keep the distance ‘a’.
lDo not machine under ‘b’ value.
lWhen machining, fix the flywheel exactly not to exceed the
standard runout.

Replacement Procedure
1. Drill a hole into the ring gear (1) (arrow) and snap
with a chisel.
2. Thoroughly clean the collar surfaces of ring gear.
3. Measure diameter (a) of centering collar.
Notice
If out of standard, replace the flywheel.
4. Heat up the new ring gear up to 220°C by using a
heating device.
Notice
Use temperature measuring chalk.
5. Install the new ring gear (1) onto the flywheel by using a

Checking
Notice
The noise which continues short time during short travel
(frequent starting of the engine) or engine starting after a
long time storage is normal operating conditions. So, it does
not need to be repaired. Determine the malfunctions in valve
clearance compensation device with noise through following
tests. If defective, replace as respectively.
1. Run the engine at more than 3000rpm for approx. 4 minutes.
2. Stop the engine. After 5minutes, check the engine oil level
and adjust if necessary.
3. Remove the cylinder head cover.
4. Check the valve tappets at TDC position of each cylinders.
5. Using a drift, lightly press the valve tappet and measure
clearance between the cam and valve tappet.
Notice
If the clearance exceeds 0.4mm, replace the valve tappet.
6. If a valve tappet moves down too far in comparison to the
others, replace the valve tappet.
7. Rotate the engine and check the remaining valve tappets.
Notice
lUnnecessary rotation of the engine will damage the valve
tappets.
lDo not rotate the engine by using the camshaft sprocket
bolt or to the opposite direction of the engine rotation.
