The inverted Duo-Cone seals have one rubber toric ring (1) on the inside diameter of the shaft seal ring (3) and a rubber O-ring (4) on the outside diameter of the retainer seal ring (5). The contact band (C) on the inverted Duo-Cone seal wears from the inside diameter toward the outside diameter.Recommendations for Reusing Seals
Undercarriage reconditioning costs can be reduced by reusing Duo-Cone seals when possible. Inspect seals and determine if the seals can be reused every time you repair or rebuild idlers or rollers.Use the following criteria to determine if the seals can be reused:
Seals should only be reused as matched pairs. If either seal of a pair cannot be reused, discard both seals.
Seals must have operated without leaks before disassembly.
Measure CONVENTIONAL seals from the INSIDE diameter to the contact band.

Reuse the CONVENTIONAL Duo-Cone seals, if the contact band (C) is 3.17 mm (0.125 inch) or farther from the INSIDE diameter of the seal ring edge.
Measure INVERTED seals from the OUTSIDE diameter to the contact band.

Use again if the contact band (C) is continuous and well-defined on the seal ring faces. The contact band (C) must be shiny and polished. Examine the contact band (C) carefully in reflected light.
Illustration 7 g02361798
Do not use again if the contact band (C) is not continuous and has scratches, pitted areas, chips, or other damage. Refer to Illustration 7. Discard both seals of the matched pair.
Illustration 8 g02361799
Do not use again if the contact band (C) is rusted. Refer to Illustration 8. Discard both seals of the matched pair.
Illustration 9 g02361800
Do not use again if the contact band (C) has corrosion and pitting at the edge. Refer to Illustration 9. Discard both seals of the matched pair.
Illustration 10 g02361801
Do not use again if the contact band (C) has galling. Refer to Illustration 10. Discard both seals of the matched pair.
Illustration 11 g02361802
Do not use again if the seal ring ramp (6) is shiny and polished as shown in Illustration 11. Discard both seals of the matched pair. The seal ring ramp (6) must have a dull (not polished) finish. A shiny or polished ramp indicates that the rubber toric was slipping on the ramp during machine operation.
