The Husqvarna 510439501 Gearshift Lever is a genuine OEM replacement designed for the DM406 concrete core drill. Sourced directly from Husqvarna, this component matches the original part in form, fit, and function — ensuring a seamless installation without guesswork. DHS Equipment supplies this part to help keep your core drill operating at full capability.
Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's original specifications, with the precise engagement geometry required for reliable gear selection on a core drill motor.
- Direct Drop-In Replacement — Matches the original mounting points and lever profile of the DM406, allowing straightforward installation without additional hardware or modification.
- Confirmed DM406 Fitment — Verified for the Husqvarna DM406 concrete core drill; cross-reference 510439501 against your parts diagram before ordering to confirm compatibility with your serial range.
- Restored Gear Selection Control — A correctly functioning gearshift lever gives the operator full, positive control over drill speed settings — critical when matching core drill RPM to bit size and material hardness.
- Protects Drivetrain Components — Proper lever engagement ensures gears seat fully, preventing the partial engagement that can accelerate wear on the internal transmission and motor assembly.
The gearshift lever on a core drill motor is the operator's direct interface for switching between speed ranges — typically a lower gear for large-diameter bits in hard concrete and a higher gear for faster drilling in softer materials. When this lever is worn, cracked, or damaged, clean gear engagement becomes difficult, leading to imprecise speed selection, potential drivetrain stress, and reduced control over drilling performance. Replacing a worn lever with a genuine OEM part like the part restores sharp, positive engagement and keeps the drill responding accurately to the operator's input.
