Good To Know

Q: What does this kit seal? A: It seals the crankshaft where it exits the crankcase to stop oil loss and air leaks. Both sides should be addressed together during a rebuild.

Q: Do I need any special tools? A: Seal removal and install typically need a puller and a suitable driver to seat the new seals square. Follow the service manual torque and installation steps for the 720 engine.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
