Description
Overview:
This Cab Mounting Upper is a non-genuine replacement for JCB mini excavators, made to replace OEM part number 331/51830. It is a rubber-and-steel bonded anti-vibration mount that secures the cab to the chassis and isolates shocks from the undercarriage. By controlling movement and reducing vibration, it helps protect the cab structure, maintains alignment, and improves operator comfort during long shifts. Built for everyday site use, it is suitable for JCB compact machines such as the 8014 and 8016, and is an economical alternative to genuine parts while remaining compatible with the original fixings. Designed as a direct-fit part, it supports safe, smooth operation and helps extend the service life of surrounding components by reducing vibration transfer.

Typical Applications:
Used on JCB mini excavators to mount the cab securely to the upper structure, improving comfort and control when digging, grading, or tracking on rough ground.
