Checking the pistons, piston rings and cylinder bore
Checking the thermal gap of piston rings Will drive ring from above at right angles to the bottom of the cylinder bore at a distance of about 15 mm from its edge.
Checking piston ring gap height
Before checking, clean the annular groove.
Checking the pistons
Measured approximately 10 mm from the bottom edge, perpendicular to the piston pin axis. The maximum permissible deviation from the nominal size - max. 0.04 mm.
Check the diameter of the cylinder Swipe crosswise measurements at three locations in the transverse direction A and the longitudinal direction B. The maximum permissible deviation from the nominal size of 0.08 mm.
NOTE Measurement of the cylinder can not produce if the cylinder block is fixed tilter engine and gearbox on the bench, since errors can occur when measuring. |
Dimensions of pistons and cylinders
NOTE The dimensions do not include graphite coating (thickness 0.02 mm) graphite coating wears away over time. |
