How to install the DDS dual-lip oil seal with rubber-enclosed case?

To install the DDS TCN-type seal, ensure the housing bore is clean and free of burrs. Use a seal driver or press to apply even force on the outer case edge, never on the lip. Lubricate the seal lips with compatible oil before installation. Avoid cocking the seal during insertion to prevent leakage.
