Clutch / disc + pressure plate / VST Fieldtrac 270D/927 / BFA10A00020A0

Clutch, pressure plate + clutch disc for VST tractors , VST Fieldtrac 270D series, VST Fieldtrac 927 and others.

The clutch disc pressure is an element connecting the gearbox with the engine and is therefore responsible for transferring torque from the engine, through the gearbox, to the tractor's running gear. Simplifying this entire complicated process, the clutch pressure is responsible for moving the tractor, starting, stopping and changing the speed ratio. The clutch pressure plate consists of a housing, release springs and a disc, and its main task is to exert an appropriate friction force on the clutch disc, a force sufficient to prevent these two elements (pressure plate and disc) from rotating at different speeds.

The clutch disc is the element responsible for transferring power from the engine (crankshaft) to the gearbox (clutch shaft). The disc is composed of a hub with a spline, which is mounted on the clutch shaft and a disc with springs with appropriately thick friction linings. The disc pressed by the second element of the clutch, the pressure plate, uses the frictional force (no friction at the moment of power transmission) of these two elements, and sets the tractor in motion. The springs in the clutch discs are responsible for reducing vibrations produced at high engine speeds.

The first signs of clutch disc wear (abrasion) are the so-called slipping of the clutch, which makes it difficult or impossible for the vehicle to move and means that when the engine speed increases, the tractor does not accelerate. The clutch disc may show signs of wear, even when it is dirty with oil. It is recommended to replace the disc together with the clutch pressure plate and release bearing, because all these elements have comparable durability and wear out at the same rate. Another sign of worn clutch disc is the inability to shift into gear.

The first signs of a worn clutch are an unnatural sound when pressing or squeezing the clutch pedal, an unpleasant odor or a grinding noise in the gearbox. When replacing the clutch, it is recommended to replace all elements (disc, pressure plate, bearing) because these elements often wear out at the same time.
