The Dipper Arm Pin 811/50178 is a precision pivot pin designed for use in the arm and linkage assembly of compatible JCB mini excavators. The official JCB parts listing specifies 811/50178 as a Pin Pivot measuring 30 × 174 mm.
This pin supports smooth articulation between components of the excavator arm assembly and helps maintain correct alignment during machine operation. Replacement of a worn or damaged pin can help reduce excessive play and maintain proper movement of the linkage.
The part number is also referenced as 811/50178, 811/50178 and 81150178. Parts catalogues and aftermarket references associate it with JCB 801-series mini excavators, but exact fitment should be confirmed using the machine model and serial number before purchase.
