Description
Overview:
This Offset Pulley is a genuine Husqvarna part designed for the belt drive system on Husqvarna ride‐on mowers, including the R13C and R422Ts. It redirects and aligns the drive belt to maintain correct tracking and tension, helping to reduce belt wear and vibration. The pulley is made from robust pressed steel with a corrosion‐resistant finish and features an integrated sealed bearing for smooth, quiet rotation. Its offset hub positions the belt path precisely where required within the deck or drive assembly. Engineered to OEM specification, it is a direct replacement for Husqvarna OEM No. 506 90 56‐01, helping restore reliable performance and extending the service life of related components such as belts, idlers, and spindles.
Key Features:
- Genuine Husqvarna replacement for OEM No. 506 90 56‐01 for assured compatibility and fit
- Pressed steel construction with durable finish for long service life in outdoor conditions
- Integrated sealed bearing for smooth running and reduced maintenance
- Offset hub for accurate belt alignment and improved belt tracking
- Helps minimise belt slip, heat build‐up, and premature belt wear
- Direct‐fit design for straightforward installation with standard workshop tools
- Stable, true running to reduce vibration and noise during mowing
- Suitable for mower deck and drive system layouts used across multiple Husqvarna Rider models
Typical Applications:
Used on Husqvarna Rider mower deck and drive systems to guide or tension the drive belt. Ideal when replacing a worn, noisy, seized, or damaged pulley to restore smooth belt routing, stable blade drive, and reliable traction drive on domestic and professional ride‐on machines.
