Tractor Clutch

The tractor clutch is installed between the engine and the gearbox, and its main function is to interrupt the transmission of power when necessary to ensure that the tractor starts smoothly; to ensure the smooth operation of the driveline when shifting; to limit the maximum torque that the driveline can bear to prevent drive train overloaded.


How Tractor Clutches Work

The tractor clutch is mainly composed of an active part, a driven part, a pressing device and a control mechanism. When the tractor clutch is in the engaged state, the pedal is in the high position, there is a gap between the release lever and the release bearing, and the pressure plate presses the driven plate under the action of the compression spring, so that the driven plate and the flywheel are tightly combined, and the engine torque is reduced by the driven disc is transmitted to the transmission.

When the driver steps on the pedal, after the clearance is eliminated through the pull rod, the separation fork and the separation sleeve, the outer end of the separation lever pulls the pressure plate to overcome the pressure of the compression spring and then moves backward, so that the pressure on both sides of the driven plate disappears. As a result, the friction force disappears, the torque of the engine is no longer transmitted to the transmission, and the clutch is in a disengaged state.


Applicable Models

Applicable to: All series of Dongfanghong, All series of Weichai Lovol, John Deere, Shanghai New Holland, Kubota, Case New Holland, Dongfeng, Changfa, Qingjiang, Taishan, Ferguson, Shuhe, Ward, Ningbo Deere , Boma, Tiantuo, Huaxia, Shifeng, Huanghai Jinma and other mainstream models of various types of tractor clutch assemblies.


Tractor Clutch Installation

When installing the driven friction plate assembly on the tractor clutch, make the shorter ends of the two driven disc hubs face each other. If two long hubs or one long hub end and one short hub end are opposite, the moving piece will be suspended between the two driven discs, resulting in the inability to transmit torque and causing the tractor clutch to slip.

The models of the tractor clutch outer bearings are 60206 and 602024, both of which are single five-pointed star concentric ball bearings with an oil-proof cover on one side. When installing, the side of the two bearings with the oil cover should face the inner cavity of the clutch to prevent the bearing during operation. The butter inside is thrown onto the surface of the friction plate, causing the tractor clutch to slip.

When installing the tractor clutch, tighten the 6 nuts on the cover of the casing and tighten them diagonally several times. After tightening, the end should not protrude from the side of the V-belt groove to avoid rubbing the belt.

When installing the clutch release claw seat of the tractor, pay attention to keeping the oil collection groove of the release claw seat directly below to avoid the lubricating oil being thrown into the clutch shell and causing the transmission belt to slip.

The so-called clutch is to use “off” and “on” to transmit the right amount of power. The clutch consists of a friction plate, a spring plate (the tractor uses a disc spring, and the harvester uses a diaphragm spring), a pressure plate and a power take-off shaft. It is arranged between the engine and the […]
