JCB Kingpost Pin Bolt Washer 54x16x10mm - 231/80608
This 10 mm thick spacer washer is designed to secure the main kingpost pin bolt in JCB 801 series mini excavators. Thanks to its significant thickness and precision manufacturing from high-hardness steel, this washer effectively distributes the bolt's clamping force, preventing it from loosening and protecting the kingpost mounting seat from deformation under heavy loads.

Workshop Tip: The kingpost pin bolt carries enormous stress during digging. Using a standard, thin washer instead of the reinforced 10 mm washer will lead to it bending and the pin loosening, which quickly results in the kingpost seats becoming worn out (ovalized). During every inspection of the kingpost play, check if the washer is cracked or deformed.
