Removal Procedure
Start By:
a. Remove the engine oil pump. 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: 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.
1. 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.
2. 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.
3. Carefully rotate the crankshaft in order to give
access to both pair of connecting rods.
4. Remove the bearing shells from the connecting
rods and the caps.
5. 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".
