INDICATOR 4234046 - Caterpillar

IMPORTANT: Toric rings (2) must never slip on the ramps of either seal rings (1) or seal ring housings (5). To prevent slippage, wait a minimum of two minutes to let the isopropyl alcohol evaporate before further assembly. Once correctly in place, the toric ring must roll on the ramps only. 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 And Installation Of Inverted Duo-Cone Seals
IntroductionThis instruction gives the procedure for installing Inverted Duo-Cone SealsReference 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.

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 suitable cloth 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). 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
