Piston Pin And Pin Bore; Conrod Small End I.d.; Conrod Deflection And Big End Side Clearance - Suzuki Vinson LT-A500F Service Manual

PISTON PIN AND PIN BORE

Measure the piston pin bore diameter using the small bore
gauge. If the diameter exceeds the service limit, replace the
piston with a new one.

Measure the piston pin outside diameter at three positions
using the micrometer. If any measurement exceeds the service
limit, replace the piston pin with a new one.

CONROD SMALL END I.D.

Measure the conrod small end inside diameter using the small
bore gauge.
If the conrod small end inside diameter exceeds the service
limit, replace the conrod with a new one.

CONROD DEFLECTION AND BIG END SIDE CLEARANCE

Wear on the big end of the conrod can be estimated by checking
the movement of the small end of the rod. This method can also
be used to check the extent of wear on the parts of the conrod's
big end.

Push the big end of the conrod to one side and measure the
side clearance using a thickness gauge. If the clearance
exceeds the service limit, replace the crankshaft assembly with
a new one or bring the deflection and the side clearance within
the service limit by replacing the worn parts (conrod, big end
bearing, crank pin, etc.) with new ones.
