12. How long should the forward clutch disks last in the reversing gear?

Indefinitely. The forward clutch disks are faced with a very durable bronze material instead of the asbestos material used on automotive type of clutches (with which most of us are much more familiar). The forward clutch assembly is lubricated by a constant supply of engine oil flowing through, and around, the disks.

The in-service life of the forward clutch assembly is more like an industrial application (engage and stay engaged for long periods of time) than it is an automotive application (engage and disengage at every street corner). - Updated: November 4, 2003
