Title:
PLATE,PINION (KU-RD41117370)
Description:
The Kubota PLATE, PINION (KU-RD41117370) is a precision-machined component used within the swivel motor and gear case assembly of compatible Kubota excavators. It works alongside the pinion shaft, bearings, seal plate, pinion plate 2 and other internal gear-case components to maintain the correct arrangement of the swivel motor assembly. The plate forms part of the pinion shaft support arrangement, helping the rotating components operate in their intended position as the swivel motor transfers power to the excavator’s swing mechanism. Kubota parts diagrams identify RD411-17370 as PLATE, PINION and position it directly alongside RD411-17360, PLATE, PINION 2, within the swivel motor component assembly.
