Installation Notes and Tips

Verify the shaft diameter, housing bore, and seal orientation before installation. Match the 23.0 mm inside diameter, 40.0 mm outside diameter, and 14.0 mm thickness to the transmission specification, and confirm the right-hand twist swirl type is oriented correctly for the application. Inspect the shaft surface and seal bore for wear, scoring, or contamination before fitting the new seal.
