40005784 Volvo.Penta Tube

Note: Refer to Specification UENR0995 "Engine Design" for non-specified engine Torque Values.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Discard all used Connecting Rod fasteners.
Note: If all connecting rod bearings require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 4 and 2 with 3. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders. Refer to Disassembly and Assembly, "Connecting Rod Bearings - Install" for the correct procedure.

Remove bolt (2), the O-ring seal, and oil pump screen (1).
Illustration 2 g02798267
The connecting rod and the connecting rod cap should have an etched Number (X) on the side. The number on the connecting rod and the connecting rod cap must match. If necessary, make a temporary mark on the connecting rod and connecting rod cap (4) in order to identify the cylinder number.
Remove bolts (3). Remove connecting rod cap (4) from the connecting rod.
Illustration 3 g02798268
Carefully push connecting rod (5) into the cylinder bore until connecting rod (5) is clear of the crankshaft. Remove lower bearing shell (7) and then remove upper bearing shell (6) from connecting rod (5). Keep the bearing shells together.
Repeat Step 3 through Step 4 for the remaining bearing shells.Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Discard all used Connecting Rod fasteners.
Ensure that the bearing shells are clean and free from wear and damage. If necessary, replace the bearing shells.

Illustration 5 g02798267Note: Connecting rods and bearing are marked with color codes. The color codes are blue and unmarked. The bearings must match up with the corresponding connecting rods. It is possible to have different color codes in the same engine.
Install upper bearing shell (6) into connecting rod (5). Ensure that the locating tab for the upper bearing shell is correctly seated in the slot in connecting rod (5). Note: The ends of the upper bearing shell must be centered in the connecting rod. The ends of the upper bearing shell are to be positioned equally in relation to the mating faces of the connecting rod.
Lubricate upper bearing shell (6) with clean engine oil.
Carefully pull connecting rod (5) against the crankshaft.
Clean connecting rod cap (4). Install lower bearing shell (7) into connecting rod cap (4). Ensure that the locating tab for lower bearing shell (7) is correctly seated in the slot in connecting rod cap (4).
Lubricate the crankshaft and lubricate lower bearing shell (7) with clean engine oil.
Install connecting rod cap (4) to the connecting rod.Note: Ensure that etched Number on connecting rod cap (4) matches etched Number on the connecting rod. Ensure the correct orientation of the connecting rod cap. The locating tab for the upper bearing shell and the lower bearing shell should be on the same side.
For the C3.3B install new bolts (3) to the connecting rod. Apply clean engine oil to the threads of bolts. Tighten the bolts evenly to a torque of 69 to 73 N m (51 to 54 lb ft).
For the C2.6 install new bolts (3) to the connecting rod. Apply clean engine oil to the threads of bolts. Tighten the bolts evenly to a torque of 45 to 49 N m (33 to 36 lb ft).

Position engine oil screen (1) and install the O-ring seal and bolt (2).
Repeat Step 2 through Step 8 for the remaining connecting rod bearings.Note: If all connecting rod bearings require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 4 and 2 with 3. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders.
