NOTICE
An improperly installed retainer ring could cause the piston and
connecting rod to come apart during engine operation. This action can
result in a broken Piston Skirt and major engine damage.
7. Position piston (1) on connecting rod (3). Coat pin (4) with clean engine oil and install pin
(4). Ensure that the retainer rings are in the grooves of piston (1).
End By:
a. Install the pistons and the connecting rods. Refer to Disassembly and Assembly, "Pistons
and Connecting Rods - Install".

NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
NOTICE
The joint between the connecting rod and the connecting rod cap is
produced by fracturing. The connecting rod assembly must be handled
with care in order to avoid damage to the mating surfaces. The
connecting rod assembly must be replaced if any damage occurs to the
mating surfaces. New connecting rod assemblies come with the
connecting rod caps bolted on the connecting rod.

29. Use only a soft jawed vise to hold the connecting rod assembly when
removing the connecting rod cap bolts. Use only a soft faced hammer
to tap the connecting rod cap when separating the connecting rod cap
from the connecting rod.
Failure to use a soft jawed vise and a soft faced hammer may result in
damage to the connecting rod assembly.
NOTICE
Always use new connecting rod bolts during the installation of
connecting rod assemblies that have fractured joints. Never reuse
connecting rod bolts during the reassembly of fractured joint
connecting rods.
Reusing connecting rods bolts during reassembly of fractured joint
connecting rods may result in engine damage.
1. Ensure that the fractured joints of the connecting rod are clean prior to installation. Use
compressed air or a wire brush to clean the joints.
2. Apply clean engine oil to the pistons, the piston rings, and the cylinder bore.

3. Position the piston rings so that the end gaps are located 120 degrees from each other.
Install Tooling (A) in order to compress the piston rings.
4. With the number one crankshaft throw at the bottom center, install the piston and
connecting rod in the engine. Ensure that the proper piston and connecting rod are in the
corresponding cylinder with the bearing retainer notch toward the right side of the engine.
The etched number on the connecting rod must be positioned on the right side of the engine.
5. Line up the piston and the connecting rod with the crankshaft. Use a soft faced hammer and
tap the piston into the cylinder bore until Tooling (A) comes off of the piston.
