S
pistons.
(a) Keep the O/S pistons.
O/S piston diameter:
O/S 0.50
O/S 0.75
O/S 1.00
(b) Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 58.8 mm (2.315 in.)
from the piston head.
(c) Calculate the amount each cylinder is to be rebored as fol-
lows:
Size to be rebored = P + C - - H
P = Piston diameter
C = Piston clearance
0.050 - - 0.070 mm (0.0020 - - 0.0028 in.)
H = Allowance for honing
0.02 mm (0.0008 in.) or less
(d) Bore and hone cylinder to calculated dimensions.
Maximum honing: 0.02 mm (0.0008 in.)
NOTICE:
Excess honing will destroy the finished roundness.
