Use the following procedure in order to install the new inner dust seal (3) and the new outer dust seal (4):
Use a wire brush in order to clean the grooves for the dust seal of the swing gear and bearing. Make sure that all of the dirt and foreign material has been removed.
Wash the grooves for the dust seal in a suitable solvent that will not leave an oily residue.
The grooves for the dust seal in the swing gear and bearing must be clean and dry prior to installation of the dust seal.
Cut one end of inner dust seal (3) at a 90 degree angle. Use a blunt tool in order to install the inner dust seal in the seal groove of the swing gear and bearing.
Install the seal so that the lip of the seal is facing in the direction that is shown.
After the inner dust seal is installed into the seal groove, measure the seal and cut the remaining end of the inner dust seal at a 90 degree angle. Install the remaining end of the inner dust seal in the seal groove.
Make sure that the inner dust seal is seated properly in the seal groove, all the way around the swing gear and bearing. Also, make sure that there is no gap between the ends of the inner dust seal.
Pull each end of the inner dust seal out of the seal groove of the swing gear and bearing approximately 50.8 mm (2.00 inch). Apply Tooling (C) to each end of the inner dust seal in order to bond the seals together.
Immediately reinstall the inner dust seal in the seal groove of the swing gear and bearing. Again, make sure that the entire inner dust seal is properly seated in the seal groove of the swing gear and bearing. No gap should exist between the ends of the inner dust seal.
To ensure that the lip of inner dust seal has not adhered to the top of the bearing at the seal joint, run a dull putty knife between the lip of the seal and the bearing at the seal joint.
Follow the procedure in Steps 1.a through 1.j in order to install outer dust seal (4) in the swing gear and bearing. Refer to Illustration 1 for proper seal orientation in the swing gear and bearing.
Lubricate the swing gear and bearing with grease.
