Description
Overview:
This kingpost carriage bearing liner is a non-genuine replacement for JCB backhoe loaders, designed to replace OEM part number 808/00388. It locates in the kingpost carriage to support smooth pivoting of the backhoe, reducing play and wear between mating parts. Precision dimensions ensure a proper press-fit and stable running clearance: length 34 mm (1.34 in), outer diameter 90 mm (3.54 in), and inner diameter 75 mm (2.95 in). Made from durable, wear-resistant material with a smooth internal bore, it is suitable for demanding site work and regular fleet maintenance. It is commonly used on popular models such as the JCB 3CX and 3DX, helping restore controlled kingpost movement and extend service intervals when rebuilding or servicing the backhoe centre mount.
