(1) Use special tools to assemble or disassemble piston ring, don’t separate piston ring too hard.
(2) Clear up the gathered carton in the ring groove; use thickness gauge or depth gauge to
measure the clearance between piston ring and ring groove. If the measured value exceeds the
limitation value, please replace piston ring or piston. If the clearance is too big, air leakage will
be caused, and then result in leakage of lube oil. Refer to picture 43.

(3) Assemble piston ring to damage parts of cylinder cover, measure piston ring gap clearance
with thickness gauge. If the measured value exceeds the limitation value, replace piston ring or
cylinder cover. Refer to picture 44
