9. Position the crankshaft for each piston and connecting rod assembly to be removed at bottom dead center.
NOTICE: The connecting rod assembly is a cracked rod design. Ensure when the bearing cap is removed that it
is placed on its side. Damage to the bearing cap will occur if it is placed on end; the connecting rod assembly will
need to be replaced if the cap is damaged.
10. Remove the connecting rod bearing cap with lower bearing shell from the connecting rod. Discard the bolts.
11. Check the connecting rod bearing cap bolts for maximum length. If any connecting rod bearing cap bolt is out of
specification, replace the out-of-specification connecting rod bearing cap bolt.
