Abstract: A system for lubricating a pivot joint including a first bushing and a second bushing and a pin disposed coaxially within a cylinder clevis, the pin having a first groove and a second groove on a first side, and third grooves on a second side and a bore along a length of the pin from first side to the second side. The first groove is used for mounting a seal. The second groove and the third grooves provide transmission of a lubricant to the first bushing and the second bushing respectively. A first cover plate and a second cover plate are fastened to the cylinder clevis using a plurality of fasteners. The first cover plate includes a first port and a second port for providing the lubricant to the first bushing and the second bushing respectively. A spring is provided between the second cover plate and the pin.

Abstract: A side wall of a movable part of an excavator bucket is disclosed. The side wall may have a sheet metal base. The sheet metal base may have an attachment portion for attaching the side wall to a rear wall of the excavator bucket. The sheet metal base may also have a cranked portion extending from the attachment portion. Further, the sheet metal base may have an extension portion extending from the cranked portion to a distal end of the sheet metal base.
