Improper positioning of seals can cause seal fallure.

Proper seal installation is important. An improperly installed seal will leak and could cause bearing failure.

Coat area of housing where seals seat, lightly with Permatex.

Pull the rubber portion of seal back and locate spring.

Apply a thin coat of lubricant to bottom seal and install with spring up toward center of housing.

Place seal squarely on housing. Select a piece of pipe or tubing with an outside diameter that will set on outside edge of seal. A tube that is too small will bow seal cage.

Carefully press seal into housing, preventing distortion to metal seal cage. Seal should seat firmly and squarely against machined shoulder in housing.

Make sure seal lip did not roll under. Distortion to seal cage or damage to seal lip will cause seal to leak. Damaged seals must be replaced.
