The Husqvarna 531123031 Stub Gear is a genuine OEM component designed for the WS440, WS440HF, WS460, WS462, and WS463 wall saws. As a direct factory replacement, this stub gear is manufactured to Husqvarna's exact tolerances, ensuring proper mesh and load transfer within the drivetrain assembly. DHS Equipment supplies this part to help keep your wall saw operating at full capacity. Cross-reference part number 531123031 against your parts diagram to confirm fitment before ordering.
Key Features
- OEM Gear Tooth Geometry — Manufactured to Husqvarna's exact tooth profile and hardness spec, ensuring correct mesh engagement and load distribution within the gearbox.
- Direct Drivetrain Replacement — Engineered to install directly into the existing gear assembly on compatible wall saws without modification to the housing or shaft interfaces.
- Broad WS Series Compatibility — Fits the WS440, WS440HF, WS460, WS462, and WS463 wall saws, covering a wide range of Husqvarna track-mounted wall saw configurations.
- Restored Cutting Power Transmission — A correctly functioning stub gear transfers motor torque efficiently to the blade drive; a worn or damaged gear causes power loss, vibration, and uneven cutting performance.
- Genuine Husqvarna Quality — Sourced directly from Husqvarna as an OEM part, this stub gear meets the same material and dimensional standards as the original component installed at the factory.
The stub gear is a critical power-transmission component within the wall saw's gearbox, transferring rotational torque from the drive system to the blade head. It works in close mesh with adjacent gears, and its tooth geometry must remain precise to maintain smooth, consistent power delivery during demanding cutting operations. When a stub gear wears or fails, operators typically notice increased vibration, noise from the gearbox, or a loss of cutting force — all signs that the gear can no longer maintain proper contact and load transfer.
