Installation of Inverted Duo-Cone Seals{7561} Caterpillar

Caterpillar Products: All

When you install Duo-Cone Seals, make sure that the following conditions exist:

• All parts of the seal are clean.

• There is no dust, lint, or grease on the seal.

• No oil is on the rubber toric, the seal ring ramps, or the housing ramps.

• The correct installation tool is used.

• The seal is correctly seated. The seal must have the same projection 360° around within 0.8 mm (0.03 inch). Refer to illustration 1. The height gage is included.

• Both seal faces are cleaned and oiled before assembly.

• The rubber toric is wetted with isopropyl alcohol. The isopropyl alcohol must contain at least 99% isopropyl alcohol.

Note: Isopropyl alcohol requires a minimum of ten minutes drying time prior to assembly. Drying time can be reduced by using filtered compressed air with less than 70 kPa (10 psi) to force dry the seal area.

Note: All safety and disposal guidelines must be followed for flammable liquids.

For further information, refer to the following documents: Special Instructions, SEHS8483, "Assembly and Installation of Inverted Duo-Cone Seals" and Special Instructions, SEHS8484, "Tool and Specifications".

The life of the seal depends on the correct installation.
