PISTON RING-TO-GROOVE CLEARANCE
• Measure the side clearances of the 1st and 2nd piston rings
using the thickness gauge.
• If any of the clearances exceeds the limit, replace both the
piston and piston rings.

PISTON RING FREE END GAP AND PISTON RING END GAP
• Measure the piston ring free end gap using the vernier cali-
pers.
• Next, fit the piston ring squarely into the cylinder and measure
the piston ring end gap using the thickness gauge.
• If any of the measurements exceeds the service limit, replace
the piston ring with a new one.
