3) Using micrometer, measure piston diameter.
4) Calculate cylinder bore diameter to be rebored as follows.
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 in.)
C : Allowance for honing = 0.02 mm (0.0008 in.)
5) Rebore and hone cylinder to calculated dimension.
6) Measure piston clearance after honing.
Check valve
Inspect check valve for clogging and ball for being stuck.
INSTALLATION
1. 26.5 mm (1.04 in.)
NOTE:
Before reboring, install lower crankcase and tighten to
specification to avoid distortion of bearing bores.
NOTE:
• All parts to be installed must be perfectly clean.
• Be sure to oil crankshaft journals, journal bearings,
thrust bearings, crank pins, connecting rod bearings,
pistons, piston rings and cylinder bores.
• Journal bearings, crankcase (bearings caps), connect-
ing rods, rod bearings, rod bearing caps, pistons and
piston rings are in combination sets. Do not disturb
combination and try to see that each part goes back to
where it came from, when installing.
• Clean mating surface of cylinder block and lower
crankcase, remove oil, old sealant and dust from mat-
ing surface.
