Face Seal Installation Procedure

1 . Clean trumpet arm and axle shaft with isopropyl alcohol, Quaker SolvoClean 68-0 or other approved evaporative solvent prior to installation of seal.

2 . Keep original mated metal sealing rings as a set for axle shaft and trumpet arm (DO NOT INTERMIX METAL RINGS).

3 . All parts of seal should be free of grease, oil, dirt and scale.

4 . Sealing rings must be handled with care. Lapped sealing faces must not be damaged, scratched or contaminated with dirt or grease.

5 . When installing the rubber toric on the seal ring, make sure that it is uniformly seated on the retaining lip and not twisted. Place the seal in the installation tool and locate assembly squarely against the housing. Use sudden and even pressure against the tool to push the toric under the retaining lip of the housing cavity. Insure the toric under the retaining lip of the tumpet arm cavity. Insure the toric is uniformly captured under the trumpet arm cavity retaining lip and is not twisted or pinched. The seal ring should be parallel to the housing within .040 [1.0 mm].

6 . After installing the seal halves into the trumpet arm and axle shaft, wipe both metal sealing surfaces clean with lint free cloth. Then apply a coat of clean MS8 oil to the metal seal faces with a lint free applicator. Oil must not wet surfaces other than sealing faces.
