1.1. Removal Procedure

Removal Procedure

Start By:

  1. Remove the engine oil pan. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install".

  2. Remove the oil supply tube assembly. Refer to Disassembly and Assembly, "Engine Oil Pump - Remove".


NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.


Note: The connecting rod and the connecting rod cap should have matching marks (6) on the right hand side. Mark the connecting rod (1) and the connecting rod cap (5), if necessary. The right side of the engine is determined from the flywheel end.

    Typical example

  1. Rotate the crankshaft until the piston is at the bottom center. Remove the connecting rod nuts (4) from the connecting rod bolts (2). Remove the connecting rod cap (5) from the connecting rod (1).

  2. Remove the lower bearing shell (3) of the connecting rod bearing from the connecting rod cap (5).

  3. Carefully push the connecting rod (1) into the cylinder bore. Remove the upper bearing shell (3) of the connecting rod from the connecting rod.

    Note: Use tape or rubber tubing on the connecting rod bolts to protect the crankshaft journals. The sharp edges of the connecting rod bolts could damage the crankshaft journals.

  4. Repeat Steps 1 through 3 for the remaining connecting rod bearings.
