The Husqvarna 506193501 Regulator Weight is a genuine OEM component designed for the K40 power cutter. As a factory-original part, it is manufactured to Husqvarna's exact specifications, ensuring proper function within the engine's speed regulation system. DHS Equipment supplies this part to help keep your K40 running at peak performance.
Key Features
- OEM-Matched Mass Tolerance — manufactured to Husqvarna's exact weight specification, which is critical for correct centrifugal governor action in the K40 engine.
- Direct Drop-In Replacement — engineered to the same dimensions and interface as the original, allowing straightforward installation without modification to surrounding components.
- K40 Power Cutter Fitment — confirmed fit for the K40 power cutter; cross-reference part number 506193501 against your parts diagram before ordering to ensure compatibility.
- Restored Engine Speed Control — a correctly functioning regulator weight allows the governor to maintain consistent engine RPM under load, preserving cutting power and smooth operation.
- Genuine Husqvarna Quality — sourced directly from Husqvarna's OEM supply chain, so the material grade and dimensional accuracy match what was installed at the factory.
The regulator weight is a key component of the centrifugal governor assembly inside the engine. As engine speed rises, centrifugal force acts on the weight to modulate fuel delivery and throttle response, keeping RPM within the designed operating range. When this part wears, deforms, or fails, the engine may hunt, over-rev, or lose consistent power under load — making timely replacement essential for safe and effective operation of the K40 power cutter.
