This adjuster spring (part number 5000156515) sits within the governor and governor lever assemblies on a wide range of Wacker Neuson engines, providing the tension that allows the governor mechanism to regulate engine speed under varying load conditions. When the spring loses tension, stretches, or breaks, the governor cannot maintain stable RPM, leading to engine surging, hunting, or uncontrolled speed variation. Replacing this spring restores the governor's ability to respond accurately to throttle and load changes.
This spring is located in the governor, governor lever, and governor control assemblies, including the BPU 3050 Governor, CT36-6 Governor Lever, Governor Lever VP 1340, Governor Lever WP 1550, and Governor Lever WP 1550W positions, among others. It is used across floor saws, vibratory plates, reversible plates, walk-behind rollers, walk-behind trowels, trash pumps, diaphragm pumps, dewatering pumps, portable generators, and modular internal vibrators.
