Clutch disc / 260 mm / 26T / Yanmar EF453T/EF494T / 198440-21401 / 6-05-100-06

Clutch disc 26T (disc pressure 6-26-102-05, 198440-21700) with an outer diameter of 260 mm (10 1/4" inch) and a hub height of 25 mm for Yanmar tractors of the Yanmar EF453T, Yanmar EF494T and other series.

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.
