How to install a DDS rotary shaft seal?

To install a DDS rotary shaft seal, ensure the housing bore is clean and free of burrs. Lubricate the seal lip and shaft with compatible oil. Press the seal evenly into the bore using a driver tool that contacts the outer case only, avoiding damage to the nitrile lip. Never hammer directly on the seal.
