Transmission oil seal 302-8432 CAT, aftermarket

For the Caterpillar machines: transmission oil seal 302-8432, an aftermarket part. This seal is used in the transmission.

A seal is chosen by inside diameter (shaft), outside diameter (bore) and width, and also by lip type and material. Seals with a dust lip are used in axles and gearboxes working in dirt, and single-lip seals in enclosed housings. A seal of the same size in a different material may harden faster at high temperature or with some oils.

Fitting

Remove the old seal without scoring the bore or shaft.

After assembly, top up the oil and check for leaks after the first run. Where possible, the new seal is set a few millimetres away from the old seal's track rather than on it.
