Piston Pin Outer Diameter
Using micrometer, measure piston pin outer diameter.
Calculation of Piston to Piston Pin Clearance
(Piston pin clearance) = (Piston pin hole inner diameter) − (Piston pin outer diameter)
●If clearance is exceeds specification, replace either or both piston/piston pin assembly.
PISTON RING SIDE CLEARANCE
●Using feeler gauge, measure clearance between piston ring and
piston ring groove.
Unit: mm (in)
●Align top ring and external surface of piston. Measure lower side
clearance of top ring with top ring pressed onto upper side of
ring groove.
●If side clearance exceeds the limit, replace piston ring.
●Check clearance again. If side clearance still exceeds the limit,
replace piston.
PISTON RING END GAP
●Check that cylinder bore diameter is within specifications. Refer
to EM-214, "
PISTON TO CYLINDER BORE CLEARANCE" .
●Using piston, press piston ring to cylinder mid point, and mea-
sure end gap.

2. install main bearing caps and tighten bolts to specified torque. This will prevent distortion of cylinder
bores.

4. Hone cylinders to obtain specified piston-to-bore clearance.
5. Measure finished cylinder bore for out- of-round and taper.
●Measurement should be done after cylinder bore cools down.
