Cylinder diameters
Clearance between piston and cylinder for new parts, mm: 0.025.
Maximum allowable clearance (when parts are worn), mm: 0.07 (model engine «NF»: 0,08).
Make measurements of the diameter of the cylinders with a caliper in three zones both in the longitudinal and transverse directions of the engine at a distance of 10 mm from the upper and lower edges and in the middle.
