Refer to SDS, EM-73.
5.
Determine piston oversize according to amount of cylinder
wear.
Oversize pistons are available for service. Refer to SDS EM-73.

D = A + B − C
where,
D: Bored diameter
A: Piston diameter as measured
B: Piston-to-bore clearance
C: Honing allowance 0.02 mm (0.0008 in)

Install main bearing caps and tighten bolts to the specified
torque. This will prevent distortion of cylinder bores.
8.
Cut cylinder bores.
+
When any cylinder needs boring, all other cylinders must
also be bored.
+
Do not cut too much out of cylinder bore at a time. Cut
only 0.05 mm (0.0020 in) or so at a time.
9.
Hone cylinders to obtain specified piston-to-bore clearance.
10. Measure finished cylinder bore for out-of-round and taper.
