Internal Governor Spring

The Hatz 1D42 Internal Governor Spring (OEM 04052900) is a replacement engine component designed for compatible Hatz diesel engines. It forms part of the engine's internal governor mechanism, providing controlled spring tension to help regulate engine speed in response to changing operating conditions and load.

Manufactured for use within the demanding environment of a compact industrial diesel engine, the spring is designed to maintain its tension and operating characteristics through repeated engine cycles. Replacing a worn, damaged or fatigued governor spring helps maintain correct governor operation, stable engine speed and reliable engine performance.

IMPORTANT INFORMATION

A governor spring operates as part of a calibrated mechanical system, so its condition can have a direct effect on engine speed and response. Inspect the spring and associated governor components for signs of stretching, corrosion, distortion or fatigue when carrying out engine maintenance.

When replacing the spring, ensure that it is correctly positioned and that all associated governor components are free from excessive wear or damage. Incorrect installation or adjustment of the governor mechanism can affect engine speed and safe operation.
