●
Measure the end gap using a feeler gauge. Replace the
ring if the service limit is exceeded.
SERVICE LIMIT : TOP / SECOND : 0.50 mm
OIL RING (SIDE RAIL) : 1.10 mm
TOOL : FEELER GAUGE
●
Measure and record the piston outer diameter 90
°
to the
piston pin bore and at the point specified (10mm), near
the bottom of the piston skirt.
