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.
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.

Place piston (2) on a suitable surface with the crown downward. Ensure the correct orientation of the connecting rod in the piston. Number (X) and number (Y) must be on the same side. Refer to Illustration 3 or Illustration 4. Install connecting rod (1) and piston pin (3) to the piston.Note: If the piston pin cannot be installed by hand, heat the piston to a temperature of 45 5 °C (113 9 °F). Do not use a torch to heat the piston.
Use Tooling (A) in order to install retaining rings (4) to the piston pin bore in piston (2) .Note: Ensure that the retaining rings are seated in the grooves in the piston.
Follow Steps 6.a through 6.e in order to install the piston rings to the piston.

Use Tooling (B) to install oil control ring (7) over the spring.Note: Ensure that the central wire is 180 degrees from the ring gap.
Use Tooling (B) to install intermediate compression ring (6) into the second groove in the piston. The letter "T" and the chamfer on the inner face of the ring must be upward.
Use Tooling (B) to install top compression ring (5) into the top groove in the piston. The letter "T" must be upward.
