Good To Know

Q: What is included in a connecting rod kit? A: A typical kit includes the connecting rod, big-end bearing, and thrust washers, which are the components needed to rebuild the lower rod end on the crankshaft.

Q: Do I need to split the crankcases to install it? A: Yes, replacing the connecting rod requires removing the crankshaft from the cases, so a full bottom-end teardown and fresh gaskets are recommended.
