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.

•

When 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’.

•

Do not machine under ‘b’ value.

•

When machining, fix the flywheel exactly not to
exceed the standard runout.

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:

•

Unnecessary rotation of the engine will damage
the valve tappets.

•

Do not rotate the engine by using the camshaft
