The Husqvarna 506372403 Piston Assembly is a genuine OEM component built for the K760 and K760II power cutters. As a direct factory replacement, this assembly ensures the correct dimensions, ring tolerances, and material grade that Husqvarna specifies for these engines — critical factors for restoring full compression and consistent power delivery. It is the right choice when an engine rebuild or top-end service is required on either machine. DHS Equipment supplies this part to help keep your equipment running at peak performance.
Key Features
- OEM Compression Tolerances — Manufactured to Husqvarna's exact bore diameter and ring-groove specifications, ensuring the piston seats and seals correctly within the cylinder for proper compression.
- Complete Assembly for Efficient Rebuild — Supplied as a full piston assembly, so all matched components install together without the need to source individual pieces separately.
- Confirmed Fitment for K760 and K760II — Engineered specifically for the K760 and K760II power cutters, cross-reference part number 506372403 against your parts diagram to verify compatibility before installation.
- Restored Engine Power Output — A correctly fitted piston assembly re-establishes the combustion seal that drives cutting performance; a worn or damaged piston causes loss of compression, hard starting, and reduced blade speed under load.
- Fuel System Integrity — Proper piston-to-cylinder clearance prevents blow-by, which can contaminate the crankcase with unburned fuel and accelerate wear on surrounding engine components.
The piston assembly is the core reciprocating component of a two-stroke engine, converting the force of combustion into the rotational power that drives the cutting blade. It must maintain a precise fit within the cylinder bore to seal compression effectively — if the piston or its rings wear beyond tolerance, the engine loses power, becomes difficult to start, and may run roughly or stall under load. Replacing the piston assembly as part of a scheduled top-end rebuild restores the engine's designed output and extends the service life of the cylinder and other internal components.
