• Bore all the four cylinders for the oversized piston outside diameter.
• Replace all the piston rings with ones to match the oversized pistons.
1. KEEP OVERSIZED PISTONS
Oversized piston diameter:
2. CALCULATE AMOUNT TO BORE CYLINDERS
(a) Using a micrometer, measure the piston diameter at right angles to the piston pin center line, 23.5 mm (0.925 in.) from the piston head.
(b) Calculate the amount each cylinder is to be rebored as follows:
Size to be rebored = P + C - H P = Piston diameter C = Piston clearance
0.079 - 0.099 mm (0.0031 - 0.0039 in.) H = Allowance for honing
3. BORE AND HONE CYLINDERS TO CALCULATED DIMENSIONS
NOTICE: Excess honing will destroy the finished roundness.
