The Husqvarna 506395701 Diaphragm Assembly is a genuine OEM component designed for the K760 and K750 power cutters. As a direct Husqvarna OEM part, it meets the original design specifications required for correct carburetor operation on these machines. This assembly is the precise replacement for K760 and K750 operators looking to restore proper fuel delivery and engine response. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Diaphragm Material — manufactured to Husqvarna's original flexible membrane specification, ensuring correct fuel-metering response and resistance to fuel exposure over time.
- Direct Carburetor Replacement — engineered to seat and seal exactly as the original, with no modification to carburetor housing or fuel lines required.
- Confirmed K760 and K750 Fitment — validated for both K760 and K750 power cutters; cross-reference 506395701 against your parts diagram before ordering to confirm correct application.
- Restores Proper Fuel Metering — a worn or cracked diaphragm causes hard starting, erratic idling, and loss of power; this assembly brings fuel delivery back to OEM operating range.
- Fuel System Integrity — a correctly functioning diaphragm is critical to preventing unmetered fuel flow, which can cause flooding or lean-running conditions that stress internal engine components.
The diaphragm assembly is a flexible membrane housed inside the carburetor that regulates fuel flow into the engine by responding to changes in air pressure during operation. It works in tandem with the carburetor's inlet needle and metering lever to deliver the correct fuel-to-air mixture at all throttle positions. When the diaphragm becomes stiff, cracked, or distorted from age or fuel exposure, the carburetor loses the ability to meter fuel accurately — resulting in hard starts, rough running, and reduced cutting performance.
