5. Place the piston on a suitable surface with the
crown downward. Install connecting rod (6) and
piston pin (7) to piston (4). Ensure that square (14)
on the piston, and slot (13) on the connecting rod
are in the correct position. See illustration 302.
Note: If the piston pin cannot be installed by hand,
heat the piston to a temperature of 45° ± 5°C
(113° ± 9°F).
6. Use Tooling (A) in order to install circlips (5) to the
piston pin bore in piston (4).
Note: Ensure that the circlips are seated in the
grooves in the piston.
7. Install upper bearing shell (9) into connecting rod
(6). Ensure that the locating tab for the upper
bearing shell is correctly seated in the slot in the
connecting rod.
8. Install lower bearing shell (10) into connecting rod
cap (11). Ensure that the locating tab for the lower
bearing shell is correctly seated in the slot in the
connecting rod cap.
9. Repeat Steps 2 through 8 for the remaining piston
and connecting rod assemblies.
Note: Fracture split connecting rods should not be
left without th
e connecting rod caps installed. After
the assembly procedure for the piston and connecting
rod is completed, carry out the installation procedure
as soon as poss
ible. Refer to Disassembly and
Assembly, “Piston and Connecting Rods - Install”.
