Specs At A Glance

Good To Know

Q: Do I need to split the cases to install these seals? A: Crank seal access varies by side and engine design, so some positions can be reached with the engine assembled while others call for case splitting. Check your service manual before starting the job.

Q: Should I replace other seals at the same time? A: If you are already resealing the crank, inspecting the surrounding gaskets, bearings, and seals is a smart move. Replacing worn parts together saves a second teardown later.

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