Suzuki VZR1800 2008 User Manual

3-42 ENGINE
PISTON AND PISTON RING
PISTON DIAMETER
• Using a micrometer, measure the piston diameter at 10 mm
(0.4 in) A from the piston skirt end.
• If the measurement is less than the limit, replace the piston.
$ Piston diameter:
Service Limit: 111.880 mm (4.4047 in)
at 10 mm (0.4 in) from the skirt end
% 09900-20210: Micrometer (100 – 125 mm)
PISTON-TO-CYLINDER CLEARANCE
• Subtract the piston diameter from the cylinder bore diameter.
(!3-41)
• If the piston-to-cylinder clearance exceeds the service limit,
replace the cylinder or the piston, or both.
$ Piston-to-cylinder clearance:
Service Limit: 0.120 mm (0.0047 in)
PISTON PIN AND PIN BORE
• Measure the piston pin bore diameter using the small bore
gauge.
• If the measurement is out of specification, replace the piston.
$ Piston pin bore I.D.:
Service Limit: 23.030 mm (0.9067 in)
% 09900-20602: Dial gauge (1/1000 mm)
09900-22403: Small bore gauge (18 – 35 mm)
• Measure the piston pin outside diameter at three positions
using the micrometer.
• If any of the measurements is out of specification, replace the
piston pin.
$ Piston pin O.D.:
Service Limit: 22.980 mm (0.9047 in)
% 09900-20205: Micrometer (0 – 25 mm)
