Pinion / 7T/14T / 161 mm / Kubota L1-18 / L1-20 / L1-22 / L1-24 / L1-26 / L1-28 / L1-R18 / L1-R20 / L1-R22

7T / 14T pinion shaft ( 5-19-127-22 ring gear, 31353- 43393, 31353-99120) of the front axle drive with a total length of 161 mm (6.34″ in) for Kubota tractors of the Kubota L1-18, Kubota L1-20, Kubota L1-22, Kubota L1-24, Kubota L1-26, Kubota L1-28, Kubota L1-R18, Kubota L1-R20, Kubota L1-R22, Kubota L1-R24, Kubota L1-R26, Kubota L1-R28 series and others.

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