2. Determining cylinder finishing diameter
(1) Measure the diameter of the oversized piston to be
used, using a micrometer.
NOTE:
• The measurement should be conducted at the skirt sec-
tion 13 mm from the piston lower end.
Perform the measurement horizontally, not in a
tiHed
state.
(2) Calculate the f1nishing dimension, as follows.
A: Piston diameter
8: Piston-to-cylinder bore clearance
0.025 - 0.045 mm
C: Honing allowance
0.02
mm
D: Finishing diameter
D=A+B-C
3. Hone the cyl'lnder after the boring.
(1) Bore the cylinder, leaving a honing allowance of
0.02
mm.
(2) Hone the cylinder.
