Good To Know

Q: Why replace the crankshaft output sleeve instead of just the seal? A: A worn sleeve can groove or pit, which prevents even a new seal from holding oil. Renewing the sleeve restores the surface the seal rides on.

Q: Does this sleeve require pressing during installation? A: Output sleeves of this type are typically pressed onto the crankshaft with the proper driver. Follow the service manual procedure and verify your model year before ordering.

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