The Husqvarna 501720901 Washer is a genuine OEM component designed for Husqvarna demolition equipment, including DXR series demolition robots and SB series hydraulic breaker attachments. As a factory-original part, this washer is manufactured to Husqvarna's exact dimensional and material specifications, ensuring correct load distribution and secure fastener seating wherever it is installed. It is a verified fit for a wide range of demolition equipment including the DXR140, DXR145, DXR250, DXR270, DXR275, DXR300, DXR305, DXR310, DXR315, DXR95, SB52, SB102, SB152, SB202, SB302, and associated demolition equipment models. DHS Equipment supplies this genuine OEM part to help keep your demolition equipment operating at full capacity.
Key Features
- Genuine OEM Material Spec — manufactured to Husqvarna's exact thickness, diameter, and material hardness requirements for correct load-bearing performance in demanding demolition applications.
- Direct Hardware Fit — this washer seats correctly against the mating fastener and surface geometry of the original assembly, requiring no shimming or modification to fit.
- Broad Demolition Equipment Compatibility — fits DXR series demolition robots and SB series hydraulic breaker attachments across multiple generations, including DXR140, DXR275, DXR305, SB102, SB202, and more. Cross-reference part number 501720901 against your parts diagram to confirm your specific model.
- Preserves Fastener Integrity — a correctly sized washer distributes clamping load evenly, protecting bolt heads, threads, and mating surfaces from damage caused by uneven stress or undersized hardware.
- Structural Assembly Confidence — using the correct OEM washer in critical joint assemblies on high-vibration demolition equipment maintains the structural integrity of the connection over the service life of the assembly.
A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it secures. By spreading clamping force over a wider area, it prevents the fastener from pulling through or damaging the mating surface, and helps maintain consistent clamping pressure under vibration and dynamic loads. On heavy demolition equipment like the DXR series robots and SB breaker attachments, where operating forces are extreme and consistent, using a washer of the correct diameter, thickness, and material grade is essential to the long-term integrity of any bolted joint it is part of. Installing an incorrect or worn washer risks fastener loosening, surface damage, or premature failure of the surrounding assembly.
