2. Measure:
• piston pin outside diameter a
Out of specification → Replace the piston
pin.
Piston pin outside diameter
11.9 ~ 12.1 mm
<Limit>: 11.88 mm
3. Measure:
• piston pin bore diameter (in the piston) b
Out of specification → Replace the piston.
Piston pin bore diameter (in the
piston)
19.004 ~ 19.015 mm
<Limit>: 19.045 mm
4. Calculate:
• piston-pin-to-piston clearance
Out of specification → Replace the piston
pin.
Piston-pin-to-piston clearance =
Piston pin bore diameter (in the piston)
b –
Piston pin outside diameter a
Piston-pin-to-piston clearance
6.904 ~ 7.115 mm
<Limit>: 7.165 mm
