Required Tools
Tool Part Number Part Description Qty
A 1P-1857 Retaining Ring Pliers 1
B 1U-6683 Ring Expander 1 Start By:
Remove the pistons and the connecting rods. Refer to Disassembly and Assembly, "Piston and Connecting Rods - Remove" for the correct procedure. Note: Make a temporary mark on the components of the piston and connecting rod assembly. Marking the components will ensure that the components of each piston and connecting rod assembly can be reinstalled in the original cylinder. Mark the underside of the piston on the front pin boss. Do not interchange components.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g02513777
Remove bolts (12) and connecting rod cap (11) from connecting rod (6). Discard the bolts . Note: Fracture split connecting rods should not be left without the connecting rod caps installed. After the disassembly procedure for the piston and connecting rod is completed, carry out the assembly procedure and the installation procedure as soon as possible. Refer to Disassembly and Assembly, "Piston and Connecting Rods - Assemble" and Disassembly and Assembly, "Piston and Connecting Rods - Install" for the correct procedure.
Remove lower bearing shell (10) from connecting rod cap (11). Remove upper bearing shell (9) from connecting rod (6). Keep the bearing shells together.
Illustration 2 g02513720
Place the piston and connecting rod assembly on a suitable surface with the connecting rod upward. Use Tooling (A) in order to remove circlips (5). Note: Note the position of the forged Mark (X). The forged mark is for the purposes of correct orientation of the connecting rod assembly and piston assembly.
Remove piston pin (7) and connecting rod (6) from piston (4). Note: If the piston pin cannot be removed by hand, heat the piston to a temperature of 45 5 °C (113 9 °F). Do not use a torch to heat the piston. Note the orientation of connecting rod (6) and piston (4).
Place the piston on a suitable surface with the crown upward. Use Tooling (B) in order to remove compression rings (1) and (2), and oil control ring (3) from piston (4). Note: Identify the position and orientation of compression rings (1) and (2), and oil control ring (3).
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.
Inspect the connecting rod for wear and damage. If necessary, replace connecting rod (6) or replace the bush for piston pin (8). Note: If the connecting rod or the bush for the piston pin are replaced, refer to Specifications, "Connecting Rods" for the correct procedure.
Repeat Step 1 through Step 6 in order to disassemble the remaining pistons and connecting rods.
