3. Using micrometer, measure piston diameter.
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 (0.0008 - 0.0015 inch)
C: Allowance for honing = 0.02 mm (0.0008 inch)
5. Rebore and hone cylinder to calculated dimension.
NOTE: Before reboring, install all main bearing caps in place and tighten to specification to avoid distortion of bearing bores.
6. Measure piston clearance after honing.
