Description
Overview:
The Knob Assembly for JCB backhoe loaders and telehandlers is a replacement control knob designed to restore a firm, reliable grip on the machine's control lever. It is a non-genuine part that directly replaces OEM reference 128/12639. Built from hard‐wearing materials with a robust, black finish, it withstands tough daily use on site or farm. The knob helps deliver smooth, predictable control of loader and hydraulic functions, supporting safe and accurate operation. It is suitable for a wide range of JCB machines, including popular models such as the 2CX and 3CX. A practical, direct-fit solution for worn, cracked or missing knobs, it allows a straightforward swap to get your machine back to work with minimal downtime.
