The Husqvarna 541400459 Pinion Gear DS 800 is a genuine OEM replacement component designed for the DS800 concrete core drill. As a factory-sourced part, it is manufactured to Husqvarna's exact specifications, ensuring correct gear geometry and material hardness for dependable drive engagement. DHS Equipment supplies this part to help keep your DS800 core drill running at full capability.
Key Features
- Genuine OEM Gear Integrity — Manufactured to Husqvarna's exact tooth profile and material hardness specifications, ensuring consistent torque transfer and long service life in demanding core drilling conditions.
- Direct Drop-In Replacement — Engineered to match the original mounting interface and gear mesh of the DS800 drill stand, allowing straightforward installation with no improvised fitting.
- DS800 Core Drill Compatibility — Specifically designated for the DS800 concrete core drill stand, cross-reference part number 541400459 against your parts diagram to confirm correct application before ordering.
- Restored Drive Performance — A worn or damaged pinion gear causes erratic feed movement and uneven drilling pressure; replacing it with this OEM component restores smooth, controlled feed operation.
- Husqvarna-Sourced Quality — Supplied through an authorized Husqvarna construction parts channel, this component meets the same build standard as the gear originally installed at the factory.
The pinion gear is a core element of the drill stand's feed drive mechanism, translating rotational input into the controlled vertical movement that advances the drill motor along the mast. It meshes with a rack or drive gear to regulate the speed and force with which the core bit is fed into the concrete. When the pinion gear wears or chips, the feed becomes inconsistent — resulting in poor core quality, excessive bit wear, and potential loss of control over drilling depth. Replacing this component in the DS800 restores precise, repeatable feed action and protects both the drill motor and the diamond core bit from the stress caused by uncontrolled advancement.
