Description

Throttle pedal spring for Mach 201 – 1 ton Thwaites dumper with Yanmar 3TNV76-KWA engine
+ Various other Thwaites dumpers

The Throttle Return Spring T105945 is an authentic Thwaites part designed to ensure safe and predictable engine control on site. Crafted from durable metal in a tightly wound coil, it delivers precise tension, allowing the throttle to return smoothly to idle when the lever or pedal is released. This helps prevent unintended engine speed, keeping dumper operation controlled and consistent.

Made to Thwaites OEM standards, it provides a reliable, direct fit on models such as the Mach 201 and 1 Tonne Hi-Tip Dumper. Built for heavy-duty environments, the spring integrates seamlessly with existing throttle linkages, minimizing downtime during installation or servicing.

Key Features:

  • Genuine Thwaites OEM part for guaranteed compatibility and quality

  • Precisely engineered length and tension for stable idle return

  • Durable metal coil construction for long-lasting performance in tough site conditions

  • Prevents sticking throttles and unintended engine speed increases

  • Accurate fit for specified models; no modifications needed
