The Husqvarna 525393401 Gear Housing is a genuine OEM structural component designed for the DM700 and DM650 concrete core drills. As a direct Husqvarna OEM part, it is manufactured to the same specifications as the original, ensuring proper alignment, torque transfer, and mechanical integrity within the drivetrain. DHS Equipment supplies this part to help keep your core drilling equipment operating at full capacity.
Key Features
- OEM-Engineered Housing Construction — Built to Husqvarna's dimensional and material specifications, ensuring the internal gear train is correctly housed, aligned, and protected under the high-torque demands of core drilling.
- Direct Structural Replacement — Engineered to mount in the same position as the original, with matching bolt patterns and interface geometry for a clean installation on DM700 and DM650 drills.
- Compatible with DM700 and DM650 Core Drills — Verified fitment for both the DM700 and DM650 concrete core drill models. Cross-reference 525393401 against your parts diagram before ordering to confirm applicability to your unit.
- Restored Drivetrain Integrity — A damaged or cracked gear housing compromises gear mesh, lubrication retention, and shaft support. Replacing it with this OEM component restores the mechanical foundation the drill depends on for consistent, controlled core drilling.
- Genuine Husqvarna Part — Sourced directly from Husqvarna's construction equipment parts program, this housing meets the original design intent — no substitute materials or off-spec tolerances.
The gear housing is the structural enclosure that surrounds and supports the drill motor's gear train, maintaining precise gear alignment and containing the lubrication that keeps internal components running smoothly under load. It also serves as the rigid interface between the motor and the drill stand or feed mechanism, so any cracking, warping, or physical damage to the housing directly affects torque transmission and drilling accuracy. When the housing is compromised, gear wear accelerates and the risk of drivetrain failure increases — making timely replacement with a correctly specified OEM part critical to restoring the drill to safe, productive operation.
