Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Ensure that all components are clean and free from wear or damage. If necessary, replace any components that are worn or damaged.
If the original piston is assembled, follow Steps 2.a through 2.e in order to install the piston rings.
Position the spring for oil control ring (3) into the oil ring groove in piston (4). The central wire must be located inside the end of the spring.
Illustration 1 g01155119
Use Tooling (B) to install oil control ring (3) over the spring. Note: Ensure that the central wire is 180 degrees from the ring gap.
Use Tooling (B) to install intermediate compression ring (2) into the second groove in piston (4). The word "TOP" must be upward. The chamfer on the inner face must be downward.
Use Tooling (B) to install top compression ring (1) into the top groove in piston (4). The word "TOP" must be upward.
Position the piston ring gaps at 120 degrees away from each other. Note: A new piston assembly is supplied with new piston rings.
Removal of the piston pin bushing in the connecting rod must be carried out by personnel with the correct training. Also special machinery is required. For more information refer to your authorized Caterpillar dealer.
If the connecting rod assembly or the bush for the piston pin have been replaced, ensure that the height grade of the connecting rod is correct. Refer to Specifications, "Connecting Rod" for further information.

Lubricate bush (7) and lubricate the bore for the piston pin in piston (4) with clean engine oil.
Illustration 3 g01244172
Place the piston on a suitable surface with the crown downward. Install connecting rod (6) and piston pin (8) to piston (4). Ensure that square boss (13) on the piston, and forged mark (X) on the connecting rod are in the correct position. See illustration 3. Note: If the piston pin cannot be installed by hand, heat the piston to a temperature of 45° 5°C (113° 9°F).
Use Tooling (A) in order to install retaining rings (5) to the piston pin bore in piston (4). Note: Ensure that the retaining rings are seated in the grooves in the piston.

Aligning the connecting rod bearing in the center of the connecting rod
Note: New connecting rod bearings are supplied with an alignment tool. If new connecting rod bearings are installed, use the tool to align the bearing in the connecting rod.
Install the upper half of connecting rod bearing (9) to connecting rod (6). Ensure that the bearing is centralized in the connecting rod. Refer to Illustration 5.
Install the lower half of connecting rod bearing (10) to connecting rod cap (11). Ensure that the bearing is centralized in the connecting rod cap. Refer to Illustration 5.
Repeat Steps 2 through 8 for the remaining piston and connecting rod assemblies. Note: Fracture split connecting rods should not be left without the connecting rod caps installed. After the assembly procedure for the piston and connecting rod is completed, carry out the installation procedure as soon as possible. Refer to Disassembly and Assembly, "Piston and Connecting Rods - Install".End By:
