The measured dimension should be as
described in the following tables. If
not, replace piston.
PISTON MEASUREMENT
NEW
90.950 mm to90.966mm
SERVICE LIMIT
90.850 mm
Piston/Cylinder Clearance
Adjust and lock a micrometer to the
piston dimension.
1. Micrometer set to the piston
dimension
With the micrometer set to the
dimension, adjust a cylinder bore
gauge to the micrometer dimension
and set the indicator to 0(zero).
1. Use the micrometer to set the cylinder bore
gauge
2. Dial bore gauge
Position the dial bore gauge20 mm
above cylinder base, measuring
perpendicularly (90
°
) to piston pin
axis.
Read the measurement on the cylinder
bore gauge. The result is the exact
piston/cylinder wall clearance.
PISTON/CYLINDER CLEARANCE
NEW
0.027mm to 0.057 mm
SERVICE LIMIT
0.100 mm
NOTE: Make sure used piston is not
worn.
If clearance exceeds specified
tolerance, replace piston by a new one
and measure piston/cylinder clearance
again.
