Our crown wheel and pinion gear go through detailed testing and are designed, manufactured in matched sets for optimal performance and reduced wear. This means that your purchased parts will meet the Rockwell Meritor standards that the original manufacturers trusts.
The crown wheel & pinion are the most stressed parts of the vehicle the arrangement of these two is known as a hypocycloid. A hydrostatic drive works by either mounting the standard hydraulic system hardware onto a reservoir with an attached hydraulic motor or by bolting a housed hydraulic pump & motor to a mechanical axle.
They are used to maintain forward motion, to maintain this momentum both output drive shaft sides covers are removed & the pinion and crown wheel are swapped completely with the differential.
