Clutch release bearing / 38 x 67 x 19 mm / Kubota B7000 / 986808K2

Clutch release bearing with the symbol 986808 and dimensions 66.80 x 38 x 19 mm for Japanese tractors and mini tractors of the Kubota B series and others.

The clutch bearing, measuring 33x60x14 mm, is also known as a release bearing or thrust bearing and is the only moving element of the clutch system in a tractor engine and moves along the axis of the drive shaft in a sliding motion. When the clutch pedal is pressed, the release bearing presses against the clutch pressure plate springs, causing the pressure plate to lift, i.e., the pressure plate moves away from the friction surface clutch disc. This allows us to disengage our drive, transfer power from the engine (crankshaft) to the chassis (gearbox drive shaft), i.e. change gear or stop the tractor.

• Inner diameter: 38 mm,
• Outer diameter: 66.80 mm,

• replacement numbers: 32270-14821, 32270-14820, 32150-14821, 32150-14820

The first signs of bearing wear and the need for replacement include an unusual noise, such as a humming or buzzing sound coming from the clutch area, which usually disappears when the clutch pedal is depressed. In the case of severe damage or wear to the clutch bearing, you may experience difficulty engaging a gear. It is recommended to replace the bearing whenever one of the pressure or shield clutch components is replaced, as replacing either component requires splitting the tractor (separating the gearbox from the engine) and is a relatively expensive and time-consuming process.
