Good To Know
Q: Does this kit include the crank bearings and seals? A: This is a connecting rod kit for the lower end, so crank main bearings and seals are typically ordered separately. Check your parts diagram for the complete rebuild list.
Q: Do I need special tools to install this rod kit? A: Yes, pressing the crank apart and truing it afterward requires a press and a truing stand. A qualified small-engine machinist is recommended for the assembly.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
