Title:
LOCK, ASSY (SWD) (KU-RP85146280)
Description:
The Kubota LOCK, ASSY (SWD) (KU-RP85146280) is a genuine swing-door lock assembly designed to secure the operator’s cabin door on compatible Kubota excavators. The assembly forms part of the cabin’s door locking mechanism and works with the swing-door lever, striker, grip and surrounding hardware to keep the door securely closed during machine operation. A correctly functioning lock assembly helps maintain the proper engagement between the door and its locking mechanism, providing reliable access control and helping prevent the door from opening unintentionally while the excavator is working. Kubota parts diagrams place RP851-46280 within the CABIN / WINDOW and operator’s platform assemblies on the applicable machines. The part replaces earlier Kubota numbers RD451-46280 and RD451-46282.
