D 1U-6684 Piston Ring Compressor 1
E 8T-3052 Degree Wheel 1
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Discard all used Connecting Rod fasteners.
If the connecting rod caps were temporarily installed, remove the connecting rod caps. If necessary, thoroughly clean all of the components.
Apply clean engine oil to the cylinder bore, to the piston rings, to the outer surface of the piston and to the bearing shells for the connecting rod. Position the piston ring gaps at 120 degrees away from each other. Note: Install the bearing shells for the connecting rods dry when clearance checks are performed. Refer to Disassembly and Assembly, "Bearing Clearance - Check". Apply clean engine oil to the bearing shells for the connecting rods during final assembly.Note: Ensure that the piston and the connecting rod assembly is installed in the correct cylinder.
Rotate the crankshaft until the crankshaft pin is at the bottom center position. Lubricate the crankshaft pin with clean engine oil.
Illustration 1 g01341299
Install Tooling (D) onto piston (4). Note: Ensure that Tooling (D) is installed correctly and that piston (4) can easily slide from the tool.Note: The arrow on the top of the piston must be toward the front of the engine. The locating tab for the bearing shell of the connecting rod must be on the same side of the engine as the piston cooling jet.
Carefully push the piston and the connecting rod assembly into the cylinder bore and onto the crankshaft pin. Note: Do not damage the finished surface of the crankshaft pin.
Illustration 2 g01341300
Install connecting rod cap (2) onto connecting rod (1). Note: Ensure that etched Number (X) on connecting rod cap (2) matches etched Number (X) on connecting rod (1). Ensure the correct orientation of connecting rod cap (2). The locating tab for the upper bearing shell and the lower bearing shell should be on the same side.
Install new bolts (3) to connecting rod (1). Tighten the bolts evenly to a torque of 18 N m (13 lb ft). Note: Do not reuse the old bolts in order to secure the connecting rod cap.
Tighten the bolts evenly to a torque of 70 N m (52 lb ft).
Turn the bolts through an additional 120 degrees. Use Tooling (E) to achieve the correct final torque.
Ensure that the installed connecting rod assembly has tactile side play. Rotate the crankshaft in order to ensure that there is no binding.
Repeat Step 2 through Step 10 in order to install the remaining pistons and connecting rods.
Check the height of the pistons above the top face of the cylinder block. Refer to System Operation, Testing and Adjusting, "Piston Height - Inspect" for the correct procedure. End By:
Install the piston cooling jets. Refer to Disassembly and Assembly, "Piston Cooling Jets - Remove and Install".
Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
Install the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Install".
