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-to-groove clearance:
Service Limit (1st) : 0.180 mm
(2nd): 0.150 mm
%
Piston ring groove width:
Standard (1st) : 1.01 – 1.03 mm
(2nd): 1.01 – 1.03 mm
(Oil) : 2.01 – 2.03 mm
%
Piston ring thickness:
Standard (1st & 2nd): 0.97 – 0.99 mm
&
09900-20205: Micrometer (0 – 25 mm)
09900-20803: Thickness gauge
NOTE:
Using a soft-metal scraper, decarbon the crown of the piston.
Clean the ring grooves similarly.
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.
%
Piston ring free end gap:
Service Limit (1st) : 3.2 mm
(2nd): 2.4 mm
&
09900-20102: Vernier calipers
%
Piston ring end gap:
Service Limit (1st) : 0.50 mm
(2nd): 0.50 mm
&
09900-20803: Thickness gauge
