Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Illustration 1 g00974873
Install upper connecting rod bearing (4) in connecting rod (5). Upper connecting rod bearing (4) must be centered in connecting rod (5). Lubricate the bearing face with clean engine oil.
Clean connecting rod cap (2) and lower connecting rod bearing (3). Lubricate the bearing face with clean engine oil.
Pull connecting rod (5) into position against the crankshaft. Note: Do Not allow connecting rod (5) to contact the piston cooling jet.
Install lower connecting rod bearing (3) in connecting rod cap (2). Lower connecting rod bearing (3) must be centered in connecting rod cap (2). Lubricate the bearing face with clean engine oil. Note: Connecting rod (5) is a forging. Connecting rod (5) has been hydraulically split in order to separate connecting rod cap (2) and connecting rod (5). This process provides accurately matched surfaces. Do Not mix connecting rod cap (2) and connecting rod (5).Note: Ensure that the etched number on connecting rod bearing cap (2) matches the etched number on connecting rod (5). Ensure that the Numbers (Y) are on the same side.

Typical example
Install connecting rod cap (2).
Install new bolts (1) in the connecting rod. Tighten bolts (1) evenly to a torque of 40 N m (30 lb ft). Note: Do Not reuse the old bolts in order to secure connecting rod cap (2).
Use Tooling (A) to achieve the correct final torque. Note: If Tooling (A) is not used, place an index mark on each bolt.
Turn bolts (1) for an additional 120 degrees in a clockwise direction.
Rotate the crankshaft in order to ensure that there is no binding.
Repeat Steps 1 through 9 for the remaining connecting rod bearings. End By:
Install the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Install".
