Clutch thrust bearing 44.50 x 73.75 x 18 mm / Eurotech TK45-4B

Clutch release bearing with an internal diameter of 44.50 mm, an external diameter of 73.75 mm and a height of 18 mm with the symbol TK45-4B for Japanese tractors and mini tractors of the Kubota X series, Iseki TU series and others.

The clutch bearing is a bearing also known as a release bearing or thrust bearing , and it is the only moving part of the clutch system in the tractor engine and moves along the axis of the drive shaft with a sliding motion. When pressing the clutch pedal, the thrust bearing presses against the clutch pressure springs, causing the pressure plate to be lifted, i.e. the pressure plate will move away from the friction surface of the clutch disc and thus we can disconnect our drive, power transmission from the engine (crankshaft), to the drive system (shaft gearbox drive) i.e. change gear or stop the tractor.

The first symptoms of bearing wear and the need to replace the bearing are an unnatural noise, e.g. hum or noise coming from the clutch area, which usually disappears when the clutch pedal is pressed. In the event of severe damage or wear of the clutch bearing, there may be problems with engaging the gear. It is recommended to replace the bearing each time one of the elements of the pressure clutch or the disc is replaced, because the replacement of each of these elements results in the tractor being halved (separation of the gearbox from the engine) and it is quite an expensive and time-consuming process.
