8. Wipe seal faces (6) of seal rings (1) clean. Use a lint free cloth or paper towel. No particles of any kind are permissible on the sealing surfaces. Even a small piece from a paper towel can hold the seal faces apart and cause leakage. 9. Put a thin film of clean oil on the seal faces. Use an applicator, a disposable tissue or a clean finger to distribute the oil evenly. Be careful not to get any oil on the rubber toric rings. 10. Make sure both housings (5) are in correct alignment and are concentric. Move the parts slowly and carefully toward each other.
Do not slam seals together. High impact can scratch or break the seal components.
11. Once in place, fasten all parts tightly.Assembly & Installation Of Inverted Duo-Cone Seals
IntroductionThis instruction gives the procedure for assembling and installing Inverted Duo-Cone Seals.Reference Literature: Special Instruction Forms, SMHS8482-01, SMHS8484-01 and SMHS8689.It is most important that correct assembly and installation procedures are followed when Duo-Cone Seals are used. Many of the Duo-Cone Seal failures are the direct result of one or more mistakes made during assembly or installation of the seal components.

(10) Retainer.(11) Retainer seal ring.(12) Rubber O-ring.1. Remove any oil film, dust or other foreign matter from rubber toric (3), and from ramps (5) and (7) and lip (6) of shaft seal ring (2) and shaft (1). Use isopropyl alcohol and a clean cloth or paper towels for wiping.IMPORTANT: Never permit oil to get on rubber toric (3), shaft ramp (5), or seal ring ramp (7) before both seal rings are put together in their final assembled position (Step 14).
Avoid prolonged skin contact with isopropyl alcohol. Avoid breathing the vapors in enclosed ares without adequate ventilation and do not smoke. Do not use near open flame or welding operations or other heated surfaces exceeding 482°C (900°F).
2. Put rubber toric (3) in seal ring (2), at the bottom of seal ring ramp (7) and against retaining lip (6). Make sure that rubber toric (3) is straight in seal ring (2) and is not twisted. Be careful when you work on the rubber toric. Nicks, cuts and scratches can cause leaks. 3. Put toric stabilizer (4) on shaft (1) as shown. 4. Select the proper installation tool (See Special Instructions, Form No. SMHS8484). Hold installation tool (9) with shaft seal ring (2) and rubber toric (3) as shown. Lower the shaft seal ring and the rubber toric into a container with isopropyl alcohol until the rubber toric is completely wet.
Do not use Stanisol or any other liquid that leaves an oil film, or does not evaporate quickly.
5. With all surfaces of rubber toric (3) still wet, use installation tool (9) to position seal ring (2) and rubber toric (3) squarely on shaft as shown. Use even pressure and a slight twisting motion to slide rubber toric (3)
