10. Lubricate rubber O-ring (12) for easier assembly in retainer (10).
Do not use too much lubricant. The lubricant must not get on shaft ramp (5) or rubber toric (3) during the assembly process (see Step 14).
Use the same installation Tool (9) as used to assemble seal ring (2) and rubber toric (3) on shaft (1). See Special Instructions, Form No. SMHS8484, for the correct tool.Using this Tool and a press, insert seal ring (11) and rubber O-ring (12) in retainer (10) until rubber O-ring (12) is against the bottom of the bore in retainer (10). 11. Check assembled height (B) with a depth gauge at four locations, 90 degrees apart. The difference in height around the ring must not be more than 0.3 mm (.012in). 12. Wipe seal faces (8) of seal rings (2) and (11) 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. 13. Put a thin film of clean oil on seal ring faces (8). 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. 14. Select correct alignment sleeve (14) [See Special Instructions, Form No. SMHS8484]. Make sure O-ring (15) is installed in retainer (10). Insert alignment sleeve (14) in bores of retainer (10) and seal ring (11). Slip the assembly over shaft (1). Slowly and carefully, move alignment sleeve (14), retainer (10) and seal ring (11) together in their final position.
Do not force the seal rings together suddenly; high impact can scratch or break the seal components.
15. Once in position, install and tighten the bolts. Remove alignment sleeve (14).Assembly & Installation Of Conventional Duo-Cone Seals
IntroductionThis instruction gives the procedure for installing Conventional Duo-Cone Seals.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.
(1) Seal (2) Rubber Toric Ring (3) Housing Retaining Lip (4) Housing Ramp (5) Seal Ring Housing
(6) Seal Ring Face (7) Seal Ring Ramp (8) Seal Ring Retaining Lip (9) Installation Tool.1. Remove any oil film, dust or other foreign matter from toric rubber rings (2) and from ramps (4) and (7) and lips (3) and (8) of both seal rings (1) and housings (5). Use Isopropyl Alcohol and clean cloth or paper towels for wiping.
Never permit oil to get on the toric rings or ramps before both seal rings are put together in their final assembled position (Step 10).
Avoid prolonged skin contact with Isopropyl Alcohol. Avoid breathing the vapors in enclosed areas 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 toric ring (2) on seal ring
