Installation Procedure
Floating ring seals have highly finished surfaces. Floating ring seals are held together by toric sealing rings. The flexibility of the toric sealing rings makes the floating ring seals self-aligning. The flexibility compensates for wear on the metal faces.
During disassembly, ensure that the floating ring seals are kept together in matched sets. Always install the metal floating ring seals in pairs. Use two new seals together or use two used seals together. Never reinstall a used toric sealing ring.

Handle all parts with care to avoid nicking critical areas.
Wash off all dirt accumulation from used parts. It may be necessary to use a wire brush to clean the accumulations of dirt or rust from the bore of the seal retainers. Ensure that the parts are clean and smooth.
Remove all oil or the protective coating from floating ring seals (2) and from retainers (4) with a nonflammable cleaning solvent. Dry the seals and the retainers.
Ensure that the ramps on the retainers and on the floating ring seal are dry. Ensure that no oil is present. Check the ramps. On used parts, remove all dirt or rust deposits from the ramps with a scraper or wire brush, and smooth the surface with emery cloth.
Always install new rubber toric sealing rings (1) on floating ring seals (2). Never install a used toric sealing ring on a new floating ring seal or on a used floating ring seal.
Install toric sealing rings (1) on floating ring seals (2). Ensure that the toric sealing ring is not twisted. Ensure that the ring is straight. Ensure that the ring is against the lip. See 1.
Avoid prolonged skin contact with isopropyl alcohol. Avoid breathing the vapors in enclosed areas without adequate ventilation and do not smoke.Isopropyl alcohol is flammable. Do not use near open flame, welding operations, or around heated surfaces exceeding 482°C (900°F).
Before installation of the Duo-Cone floating seals, wet the toric sealing ring in isopropyl alcohol. Do not use stanisol or any other liquid that leaves an oily film or does not evaporate quickly.

Use correct tooling to install Duo-Cone floating seals. Duo-Cone installation tools are available. See the power Train Tools section of the Tool Guide for a list of installation tools. A typical installation tool is shown in the illustration.
If the installer tool is not used, do not use a screw driver or stick to assemble the toric sealing ring in the retainer. Use finger pressure only.
Install the Duo-Cone floating seal in retainer (4) until the toric sealing ring is under the lip of the retainer. Ensure that the toric sealing ring does not twist. See Figure (B) .
After assembly, check dimension (X) at four places at 90 degree intervals. Height variation around the assembled ring should not exceed 1 mm (0.04 inch). Use the Duo-Cone floating seal installation tool to make any adjustments. Do not push on the floating seal ring directly.
Before assembling the floating ring seals together, wait at least two minutes. Allow all the isopropyl alcohol to evaporate.
