(10) Retainer (11) Retainer seal ring (12) Rubber O-ring1. 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 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 rubber toric (3) in seal ring (2), at the bottom of seal ring ramp (7) and against retaining lip (6).IMPORTANT: 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) and seal ring (2) down shaft (1) until assembly tool (9) contacts the end of the shaft. 6. Check assembled height (A) at four locations 90 ° apart. The difference in height around the ring must not be more than 0.8 mm (.031 in). Use go/no go gauge (13), included with each Duo-Cone Seal Group, to check assembled height. See Special Instructions, Form No. SMHS8484. 7. If small adjustments are necessary, do not push or pull directly on seal ring (2). Use installation tool (9) to push down and your fingers to pull up, uniformly, on rubber toric (3) and seal ring (2).8. Rubber toric (3) may twist if it is not completely wet during installation, or if there are burrs or fins on shaft (1).
Misalignment, twists and bulges of the rubber toric will cause Duo-Cone Seal failures. If correct installation is not obvious, remove the seal from the shaft and repeat Steps 4 thru 7.
IMPORTANT: Rubber toric (3) must never slip on the ramps of either seal ring (2) or shaft (1). To prevent slippage, wait
