- Caterpillar track-type tractors (bulldozers)
- Steering clutch systems
- Transmission clutch packs
- Crawler heavy equipment
Steering Clutch System
In Caterpillar track-type tractors, the steering clutch system controls track speed differential for steering. The 4S-9072 friction disc works with steel separator plates within the steering clutch housing to transmit torque to each track independently.
- Straight travel: Both steering clutches fully engaged, equal power to both tracks
- Turning: Inner track clutch partially disengaged to slow the inner track
- Sharp turns: Inner clutch fully disengaged with steering brake applied
