Piston And Piston Ring - Suzuki GSX1400 Service Manual

PISTON AND PISTON RING

PISTON DIAMETER
• Using a micrometer, measure the piston outside diameter at
15 mm (0.6 in) from the piston skirt end.
• If the measurement is less than the limit, replace the piston.
Piston diameter:
Standard: 80.980 – 80.995 mm (3.1882 – 3.1888 in)
Service Limit: 80.880 mm (3.1843 in)
at 15 mm (0.6 in) from the skirt end
09900-20204: Micrometer (75 – 100 mm)
PISTON TO CYLINDER CLEARANCE
• Subtract the piston diameter from the cylinder bore diameter.
• If the piston to cylinder clearance exceeds the service limit,
replace the cylinder and the piston.
Piston to cylinder clearance:
Standard: 0.015 – 0.025 mm (0.00059 – 0.00098 in)
Service Limit: 0.120 mm (0.0047 in)
PISTON PINS AND PIN BORE
• Measure the piston pin bore inside diameter using the small
bore gauge.
• If the measurement is out of specification, replace the piston.
09900-20602: Dial gauge (1/1000 mm)
09900-22401: Small bore gauge (10 – 18 mm)
Piston pin bore I.D.:
Service Limit: 18.030 mm (0.7098 in)
• Measure the piston pin outside diameter at three positions us-
ing the micrometer.
• If any of the measurements are out of specification, replace the
piston pin.
09900-20205: Micrometer (0 – 25 mm)
Piston pin O.D.:
Service Limit: 17.980 mm (0.7079 in)
