Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exacting dimensional standards, this washer delivers the precise alignment geometry that the drill assembly depends on — not a generic approximation.
- Drop-In Replacement — Engineered to match the original mounting configuration, this guide washer installs directly into the drill motor without modification, restoring the assembly to its original specification.
- Broad Core Drill Compatibility — Confirmed fitment across the DM280, DM340, DM650, and DM700 drill motors, as well as the DMS280 combined drill system — one part number covering a wide range of Husqvarna core drilling equipment.
- Alignment Integrity Maintained — A correctly functioning guide washer keeps internal components properly seated and aligned during operation, preventing uneven wear and protecting surrounding parts from premature damage.
- Verified Part Number — Cross-reference part number 584390201 against your machine's parts diagram to confirm this is the correct guide washer for your specific DM or DMS model before ordering.
A guide washer serves as a precision spacer and alignment component within the drill motor assembly, controlling the positioning of moving or rotating parts and ensuring they operate on the correct axis. Without a properly functioning guide washer, internal components can shift out of alignment during drilling, leading to increased wear on adjacent parts and reduced accuracy in core drilling applications. Replacing a worn or damaged guide washer with a genuine OEM part restores the mechanical integrity of the assembly and protects the longevity of the surrounding drivetrain components.
