Suggestion for Disassembly and Reassembly Ball bearings at both ends are of maintenance free. If it is necessary to remove the bearings when repairing the motor, the bearings and seals must be replaced.
If a bearing which is to be replaced has only one sealing lip, it should be greased with quality bearing grease when installing it.

Replace the bearings and seals after approximately 10,000 operating hours.

The rear axle is coupled with the pinion gear and rack gear. The rack gear is mounted with pistons on both ends, and converts the reciprocal motion generated by oil pressure to the rotational movement of the pinion gear. The pinion gear serves as a steering device.

The steering axle connected to the pinion gear is linked to two symmetrically arranged rear wheels. The steering axle and the taper roller bearing of the pinion gear support the rear wheel load.
