PistonCylinder Clearance
The piston-to-cylinder clearance must be checked, and the standard value maintained anytime piston or the cylinder block are replaced with new parts, or whenever the cylinder is rebored and oversize pistons installedThe most accurate way to find the piston clearance is by making separate piston and cylinder diameter measurements and then computing the difference between the two valuesMeasure the piston diameter as just described, and subtract this value from the measurementThe difference is the piston clearancePistonICylinder Clearance 0.085 0.1 15 mm (0.0033 0.0045 in
