The Husqvarna 578110501 Pulley is a genuine OEM component designed for K1250, K1260, K1270, and K2500 power cutters. As a factory-original part, this pulley is manufactured to the same tolerances and material specifications as the component installed at the time of production, ensuring correct belt alignment and consistent power transfer to the cutting system. Cross-reference part number 578110501 against your machine's parts diagram to confirm fitment before ordering. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- OEM-Spec Belt Engagement — manufactured to Husqvarna's exact groove profile and diameter specifications, ensuring the drive belt seats correctly and tracks true under load.
- Direct-Fit Replacement — engineered to mount directly to the existing drive assembly on compatible power cutters, matching original bore dimensions and mounting configuration.
- Broad K-Series Compatibility — fits the K1250, K1260, K1270, and K2500 power cutters, covering Husqvarna's heavy-duty handheld cutting range in a single part number.
- Sustained Power Transfer — a correctly functioning pulley maintains efficient torque delivery from the engine to the blade, preventing belt slip, vibration, and premature belt wear that a worn or damaged pulley introduces.
- Genuine Husqvarna Quality — produced as an authorized OEM part, this pulley meets the same material hardness and dimensional standards as the original, supporting long service intervals in demanding cut-off applications.
The pulley is a critical drive-train component that routes and tensions the belt connecting the engine's output to the blade spindle on a power cutter. It maintains the mechanical advantage needed to transfer engine power efficiently, and its groove geometry keeps the belt running in precise alignment during cutting. When a pulley wears, chips, or becomes misaligned, the drive belt can slip or derail, resulting in loss of blade speed, accelerated belt deterioration, and uneven cutting performance — making prompt replacement with a correctly specified part essential to restoring full machine output.
