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.
Place bottom washer (3) on shaft and crossbar (9). Place housing assembly with bottom seal (4), bottom cone (5) and cup (7) installedover shaft and crossbar (9). Carefully guide seal over shaft and press shaft into housing.
Fill housing cavity with a medium grade grease. Place top bearing cone (5) and sleeve (2) on shaft.
Press sleeve and bearing onto shaft until all bearing free play is removed and there is a slight drag (similar to adjusting the front wheel bearings on an automobile). Check by spinning spindle. It should turn freely.
