Crown wheel 20T / 23T / 120 mm + pinion shaft 10T/18T/175 mm / Kubota M6040 / M7040 / M8540 / 5-19-127-13

Crown wheel 23T / 20T + drive pinion shaft 10T / 18T (nut 5-13-103-06, 35340-25320, bearing 6-23-112-03, 3C011-43380, oil seal 5-08-106-12, W9501-53020, 3A021-44120) of the front axle drive for Kubota tractors of the Kubota M6040, Kubota M7040, Kubota M8540, Kubota M4N-071, Kubota M5N-091, Kubota M5N-111 series and others.

The crown wheel with drive pinion shaft is a differential mechanism component responsible for transmitting drive from the engine drive shafts to the road wheels. In addition to transmitting drive, the drive unit consisting of the pinion shaft + crown wheel increases the torque transmitted by the longitudinal shaft to the transverse shaft while changing the direction of rotation.
