Good To Know
Q: Does this kit include the bearing and pin? A: Yes, the kit is supplied as a full connecting rod assembly with the rod, lower bearing, and wrist pin. Reuse of any old hardware is not recommended during a rebuild.
Q: Can I install this without machining the crank? A: Pressing the rod onto the crank and truing the assembly requires the right tooling and experience. Most riders have a machine shop handle the crank rebuild for correct runout.
