NOTE: The clearance between the piston and cylinder is checked by measuring the clearance between the piston and cylinder skirt.

124-3 PISTON and PISTON RINGS

1)If a ring expander is not available. set the ring joint at the first land of the piston. as shown in Fig. 12-l 1 so

that the ring can be slided into its groove.

NOTE: Be careful not to twist or expand exces- sively each ring. The oil ring is fitted first on to the

piston, followed by the second ring and top ring-

The top and second rings must be fitted with their marked sides kept upward.
