IMPORTANT: Pistons, connecting rods , rod
bearings, and bearing retainers are wearing parts
and seat with the operation of the engine.
Because of this, it is essential to maintain their
original positions at reassembly. Using an indeli-
ble ink marker, mark each connecting rod, cap,
and bearing component as they are removed to
ensure proper reassembly. Keep the needles of
each cylinder together.
IMPORTANT:
Loosely install cylinder head to
prevent pistons from falling out.
Remove the rod cap screws using Torquing
Socket, PIN 331638. Remove the cap's needle
bearings and cages.
