Husqvarna 598736701 Shim Washer Spare Part DM 400, DM 430

Precision spacing and alignment of drill bits on Husqvarna DM 400 and DM 430 core drilling rigs depends on proper shimming between components. This OEM shim washer maintains factory tolerances in the motor assembly, ensuring your drill operates at the correct geometry for clean, accurate holes in reinforced concrete. When you're drilling anchor points in structural slabs or creating openings for mechanical systems, worn or missing shims lead to vibration, premature bit wear, and off-angle holes that fail inspection. The 598736701 replaces damaged washers during routine maintenance or rebuild work. Keep spares on hand to minimize downtime when servicing your equipment between jobs. Built for contractors and rental houses maintaining Husqvarna DM-series drilling equipment.
