The Hatz Governor Spring Cup (OEM 03798600) is a replacement engine component used within the mechanical governor assembly of compatible Hatz diesel engines. The cup works with the governor spring and associated centrifugal governor components, helping maintain the correct positioning and operation of the spring within the governor mechanism.

Designed for use inside the engine's governor and oil pump assembly, the cup provides a small but important part of the overall speed-control mechanism. Replacing a worn or damaged cup helps maintain correct governor operation and supports consistent engine speed and response under changing engine loads.

IMPORTANT INFORMATION

The governor spring cup forms part of a precision mechanical governor assembly, so its condition can affect the correct positioning and operation of the governor spring. Inspect the cup and surrounding components for wear, damage or distortion when carrying out governor or engine maintenance.

When replacing the cup, inspect the governor spring, circlip, bearing bush and centrifugal governor components for signs of wear at the same time. Ensure all components are correctly positioned and securely retained before returning the engine to service.
