161-4164(2) Piston Ring Compressor Gp 1
B 4C-5590 Anti-Seize Compound 1
(1) 125mm bore
(2) 130mm bore
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Apply clean engine oil on the following items: the piston, the piston rings and the cylinder bore. Note: Careful handling is required for fractured connecting rods. Fractured faces for the connecting rod and connecting rod cap should not be placed on any surface. The connecting rod and the connecting rod cap should be placed on the sides in order to prevent damage. When possible, the connecting rod and the connecting rod cap should be bolted together in order to prevent damage.

With the number one crankshaft throw at the bottom center, install the piston and connecting rod (1) 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. Note: The word "FRONT" may be stamped on the crown of the pistons in some engines. Ensure that the word "FRONT" is toward the front of the engine when the piston is installed. The etched number on the connecting rod must be on the right side of the engine in the corresponding cylinder.
Line up the piston and connecting rod with the crankshaft. Use a soft hammer and tap the piston into the cylinder bore until Tooling (A) comes off of the piston.
Before the connecting rod comes in contact with the crankshaft, install the upper half of connecting rod bearing (2). Ensure that the bearing tab engages with the slot in the connecting rod.
Apply clean engine oil to the surface of the upper half of connecting rod bearing (2). Use a soft hammer in order to tap the piston into the cylinder bore while you guide the connecting rod onto the crankshaft.
Place the lower half of connecting rod bearing (2) in corresponding connecting rod cap (3). Ensure that the bearing tab engages with the groove in connecting rod cap (3).
Apply clean engine oil to the surface of the lower half of connecting rod bearing (2). Install connecting rod cap (3) on the connecting rod. Ensure that the number on connecting rod cap (3) matches the number on connecting rod (1). Ensure that the numbers are on the same side.
Apply Tooling (B) to connecting rod cap bolts (4). Install connecting rod cap bolts (4). Tighten the connecting rod cap bolts to a torque of 130 7 N m (95 5 lb ft).
Place an index mark on each bolt head. Tighten each bolt for an additional 60 5 degrees (1/6 turn). End By:
Install the piston cooling jets. Refer to Disassembly and Assembly, "Piston Cooling Jets - Remove and Install".
Install the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head - Install".
