Flywheel

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

Distortion of gasketed surface

Using straightedge and thickness gauge, check gasketed surface
for distortion and, if flatness exceeds its limit, correct it.
Flatness

Honing or reboring cylinders

1) When any cylinder needs reboring, all other cylinders must also
be rebored at the same time.
2) Select oversized piston according to amount of cylinder wear.
3) Using micrometer, measure piston diameter.
"a": 23 mm (0.91 in.)
4) Calculate cylinder bore diameter to be rebored.
D = A + B – C
D: Cylinder bore diameter to be rebored.
A: Piston diameter as measured.
B: Piston clearance = 0.02 – 0.04 mm
C: Allowance for honing = 0.02 mm (0.0008 in.)
