How to install a DDS rotary shaft seal with a rubber-enclosed case?

To install a DDS rotary shaft seal, ensure the bore is clean and free of burrs. Use a seal driver or press to apply even pressure on the outer case, never the lip. Lubricate the seal lip and shaft before installation. Avoid damaging the rubber-enclosed case, which is designed for rough bores.
