CYLINDERS AND PISTONS
5-36
TIP
Level the piston ring in the cylinder with the
piston crown.
3. Measure:
• Piston ring end gap
Out of specification
→
Replace the piston
ring.
TIP
The oil ring expander spacer end gap cannot
be measured. If the oil ring rail’s gap is exces-
sive, replace all three piston rings.

CHECKING THE PISTON PINS
The following procedure applies to all of the
piston pins.
1. Check:
• Piston pin
Blue discoloration/grooves
→
Replace
the piston pin and then check the lubrica-
tion system.
2. Measure:
• Piston pin outside diameter “a”
Out of specification
→
Replace the piston
pin.
3. Measure:
• Piston pin bore diameter “b”
Out of specification
→
Replace the pis-
ton.
4. Calculate:
• Piston-pin-to-piston-pin-bore clearance
Out of specification
→
Replace the piston
pin and piston as a set.
