Removal Procedure
Start By:
Remove the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Remove".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Remove one pair of connecting rod caps at a time and install one pair at a time. Damage can occur when the fractured split connecting rods are separated.
In order to remove the connecting rod caps, rotate the crankshaft in a clockwise direction until one pair of pistons is at the bottom center position. Note: Check that the connecting rod and the cap are correctly marked to the cylinder. If the connecting rod assembly requires marking do not punch the connecting rod assembly or stamp the connecting rod assembly as this may cause damage.
Remove the torx screws from the caps and remove both pair of caps with the bearing shells. Push both pair of connecting rods into the cylinder. Do not allow the connecting rods to contact the piston cooling jets.
Carefully rotate the crankshaft in order to give access to both pair of connecting rods.
Remove the bearing shells from the connecting rods and the caps.
Before continuing with the next pair of connecting rods, install all the new bearing shell into the connecting rods and caps. Refer to Disassembly and Assembly , "connecting rod bearing - install".
