EXCERPT:

9. Cylinder, Piston, Crankshaft
Measure the inner diameter of conrod little end
Greater than 13.05mm -> replace
Measure the outside diameter of the piston pin
Smaller than 12.98mm -> replace
Calculate the clearance between the piston and piston pin.
Greater than 0.06mm -> replace
Measure the outside diameter of a piston
Measure at 14mm from the bottom end of the skirt and perpendicular to the piston pin hole.
Smaller than 48.35mm -> replace
Cylinder Inspection
Measure the distortion of the cylinder top surface.
Greater than 0.05mm -> Adjust or replace
Inspect the inner surface of the cylinder.
Measure the inner diameter for X - Y direction at upper, middle, lower part of the cylinder, and record the six numbers.
The maximum number is considered as an inner diameter.
Greater than 48.60mm -> adjust or replace
Calculate the clearance between the cylinder and a piston by measuring the outside diameter of a piston. Take the maximum value.
Greater than 0.10mm -> adjust or replace
Calculate the following parameters and take maximum number:
Circular distortion:
= (X - direction diameter)
= (Y - direction diameter)
Cylindrical distortion:
(Difference in X or Y direction Diameter between three parts).
Both parameters should be < 0.05mm
If greater —> adjust / replace
Inspection / Selection of bearings
Crank pin bearing
Inspect the bearing for scratch,or separation.
Wipe off the oil on the bearing and the crank pin.
Attach the crankshaft.
Avoid oil hole and apply plastic gauge.
Attach the conrod bearing caps to individual crank pins and tighten the bolts.
Tightening Torque: 1.5—1.9kg m
Ensure the crankshaft and conrod do not rotate while measuring.
