^
If ring gear is damaged, cracked or worn, replace flywheel.
^
If the surface contacting clutch disc is damaged, or excessively worn, replace flywheel.
^
Check flywheel for face runout with a dial gauge. If runout exceeds its limit, replace flywheel.
Limit on runout: 0.2 mm (0.0078 inch)

Distortion of gasketed surface
^
Using straightedge and thickness gauge, check gasketed surface for distortion and, if flatness exceeds its limit, correct It.
Flatness Limit: 0.06 mm (0.0024 inch)
Honing or reboring cylinders
1) When any cylinder needs reboring, all other cylinders must also be rebored at the same time.
2) Using micrometer, measure piston diameter.
3) Calculate cylinder bore diameter to be rebored as follows.
D = A + B - C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 - 0.04 mm (0.0008 - 0.0015 inch)
C: Allowance for honing = 0.02 mm (0.0008 inch)
4) Rebore and hone cylinder to calculated dimension.
NOTE: Before reboring, install lower crankcase and tighten to specification to avoid distortion of bearing bores.
