CONNECTING RODS AND PISTONS
2. Measure:
• Piston pin outside diameter a
Out of specification → Replace the pis-
ton pin.
Piston pin outside diameter:
16.991–17.000 mm
(0.6689–0.6693 in)
<Limit>: 16.971 mm (0.6681 in)
3. Measure:
• Piston pin bore diameter (in the piston)
b
Out of specification → Replace the pis-
ton.
Piston pin bore diameter
(in the piston):
17.002–17.013 mm
(0.6693–0.6698 in)
4. Calculate:
• Piston-pin-to-piston clearance
Out of specification → Replace the pis-
ton pin.
Piston-pin-to-piston clearance =
Piston pin bore diameter (in the piston)
b – Piston pin outside diameter a
Piston-pin-to-piston clearance:
0.002–0.042 mm
(0.0001–0.0017 in)
