CAUTION: To prevent engine damage, install
connecting rod cap and connecting rod with matching
serial numbers on the same side. If the rod cap is
reversed or not installed on its matching connecting
rod, the fractured mating surfaces will be damaged.
This can loosen the rod cap. A new connecting rod
assembly must be installed.
The fractured mating surfaces of each rod and cap
pair are precisely matched. Always keep each cap
with its respective rod. If unsure, match the serial
number on each connecting rod and connecting rod
cap.
