Inspect the Clearance of the Piston
Ring
1. Remove the piston rings and clean the grooves
and the piston rings.

(2) Piston ring
(3) Piston grooves
2. Install new piston rings (2) in the piston grooves
(3).
3. Check the clearance for the piston ring by placing
a suitable feeler gauge (1) between piston groove
(3) and the top of piston ring (2) for the
intermediate ring and the oil control ring. Refer to
Specifications, "Piston and Rings" for the
dimensions.

(3) Feeler gauge
1. Clean all carbon from the top of the cylinder bores.
2. Place each piston ring (1) in the cylinder bore just
below the cylinder ring ridge (2).
3. Use a suitable feeler gauge (3) to measure piston
ring end gap. Refer to Specifications, "Piston and
g00905732
Rings" for the dimensions.
Note: The coil spring must be removed from the oil
control ring before the gap of the oil control ring is
measured.

Connecting Rod - Inspect

Note: If the crankshaft or the cylinder block are
replaced, the piston height for all cylinders must be
measured.
• New piston pin bearings must be bored after
installation in the original connecting rods. Refer to
"".
Note: When the piston pin is installed, always install
new retaining rings on each end of the piston pin. If
the piston pin cannot be removed by hand, heat the
piston to a temperature of 45° ± 5 °C (113° ± 9 °F) in
order to aid the removal of the piston pin. Heating the
piston to this temperature may also aid the
installation of the piston pin.
Piston Pin Bearings
Note: This procedure requires personnel with the
correct training and the use of specialized equipment
for machining.
