The Thwaites 6 Tonne Alldrive Top Pin Kit is a replacement top centre pivot repair kit designed for use on pre-2001 Thwaites Alldrive 5, 6, and 7 tonne dumpers. The kit is engineered to restore the upper kinglink articulation assembly, a critical component of the dumper chassis that allows controlled articulation and oscillation between the front and rear sections of the machine while maintaining stability and steering performance.
Manufactured for heavy-duty construction applications, the kit contains the essential components required to refurbish worn top pivot assemblies and restore correct chassis alignment, articulation movement, and operational safety. Centre pivot kits of this type are commonly fitted during major maintenance programmes when excessive movement or wear develops within the kinglink assembly.
FUNCTION AND OPERATION
- Restores the upper centre pivot (kinglink) assembly
- Maintains correct articulation between front and rear chassis sections
- Supports chassis oscillation and steering geometry
- Reduces excessive movement and wear within the pivot system
- Helps maintain machine stability and safe dumper operation
- Designed for demanding construction and site environments

TYPICAL APPLICATIONS
Suitable for a range of Thwaites equipment, including:
- Thwaites Alldrive 5 Tonne dumpers (pre-2001)
- Thwaites Alldrive 6 Tonne dumpers (pre-2001)
- Thwaites Alldrive 7 Tonne dumpers (pre-2001)
- Front-tip dumper models
- Power Swivel dumper models
- Kinglink chassis articulation systems
The Thwaites kinglink chassis design uses centre articulation and oscillation to improve traction, stability, and manoeuvrability on uneven terrain.
IMPORTANT INFORMATION
Always confirm the correct machine model, serial number, and centre pivot configuration before ordering, as Thwaites dumpers utilise several different kinglink and centre pivot arrangements depending on model and year of manufacture. CPKIT8 is intended for pre-2001 Alldrive 5, 6 and 7 tonne machines and differs from later centre pivot kits fitted to post-2001 dumpers. Excessive wear within the upper pivot assembly can lead to poor steering characteristics, chassis misalignment, instability during operation, accelerated tyre wear, and increased stress on surrounding articulation components. When rebuilding the centre pivot assembly, it is recommended to inspect both the top and bottom pivot components together to ensure balanced wear and long-term reliability.
