The Husqvarna 588470403 Pulley Assembly is a genuine OEM component designed for the K770, K760, and K760II power cutters. As a direct factory replacement, this pulley assembly matches the original mounting configuration and belt groove dimensions of the production part, ensuring the drive system operates exactly as engineered. DHS Equipment supplies this part to help keep your power cutter performing at full capacity. Cross-reference part number 588470403 against your machine's parts diagram to confirm fitment before ordering.
Key Features
- Genuine OEM Belt Groove Specification — Manufactured to Husqvarna's original groove profile and diameter tolerances, maintaining correct belt tension and tracking in the drive system.
- Direct Bolt-On Replacement — Matches the original mounting interface on K770, K760, and K760II power cutters for a straightforward swap with no machining or adaptation.
- Broad K-Series Power Cutter Compatibility — A single part number covers the K770, K760, and K760II, making it the correct choice across this popular family of handheld power cutters.
- Restored Drive Efficiency — A worn or damaged pulley causes belt slippage, vibration, and uneven blade speed; replacing it with this assembly brings the drive system back to consistent, full-power operation.
- OEM Quality Assurance — Sourced directly through the Husqvarna supply chain, so material grade, hardness, and dimensional accuracy reflect the same standards as the original production component.
The pulley assembly is a core element of the power cutter's belt-drive system, transferring rotational force from the engine to the cutting blade with consistent speed and torque. It works in conjunction with the drive belt to maintain the correct blade RPM under load, and its groove geometry keeps the belt seated and tracking true during operation. When the pulley wears, develops surface damage, or the bearing within the assembly degrades, the result is belt slippage, excessive vibration, reduced cutting power, and accelerated belt wear — all of which compromise both cut quality and operator control.
