Key Features
- OEM-Grade Tooth Geometry — manufactured to Husqvarna's exact tooth profile and hardness specifications, ensuring correct mesh and load distribution within the gear train.
- Drop-In Drivetrain Replacement — engineered to the original shaft dimensions and spline or bore interface, allowing straightforward installation without reworking the surrounding assembly.
- Broad Fitment Across Two Equipment Families — confirmed for K3000, K3000VAC, and K4000 power cutters, as well as the AD10 concrete core drill, covering a wide range of Husqvarna construction equipment.
- Restored Power Transmission — a worn or damaged pinion causes missed engagement, vibration, and loss of cutting or drilling torque; replacing it with this OEM component restores smooth, efficient power transfer.
- Genuine Husqvarna Part — sourced directly from Husqvarna's authorized parts network, giving you confidence that the metallurgy, heat treatment, and dimensional accuracy match the original component.
The pinion is a small but critical gear within the machine's drivetrain, responsible for transmitting rotational force from the motor or drive shaft to the larger gear set. When the pinion wears or fails, the gear mesh deteriorates — producing rattling, slipping, or complete loss of drive, which prevents the machine from delivering consistent cutting or drilling performance. Replacing a faulty pinion with a properly specified OEM part restores the mechanical integrity of the drivetrain and returns the machine to its designed operating capability.
