The Multiquip 52003-12 is a genuine OEM Star Washer #10 designed for CV and SVA series concrete vibrators. As an authentic Multiquip replacement part, the part delivers the correct material grade, tooth geometry, and dimensional tolerancing needed to maintain secure fastening under the continuous vibration loads these machines generate. This washer is confirmed to fit CV1A, CV2A, CV2B, CV3A, CV3B, CV-1, CV-2, CV-2E, CV-3, CV-3E, SVA-1, SVA-2, SVA-2E, SVA-3, and SVA-3E vibrator models. Stocking this hardware as a service item keeps routine maintenance and field repairs on schedule.
Key Features
- Vibration-Rated Tooth Profile — Star washer teeth bite into mating surfaces to resist loosening under the sustained high-frequency vibration output of concrete vibrator equipment.
- Genuine OEM Specification — Sourced directly from Multiquip, this washer matches the original material grade, outer diameter, and tooth count specified for these vibrator assemblies — no guesswork on sizing.
- Broad CV and SVA Series Coverage — A single part number covers CV1A, CV2A, CV2B, CV3A, CV3B, CV-1, CV-2, CV-2E, CV-3, CV-3E, SVA-1, SVA-2, SVA-2E, SVA-3, and SVA-3E models, making it a practical stocking item for fleets running multiple vibrator units.
- Drop-In Service Hardware — Installs in place of the original without rework — correct hole clearance and seating geometry for the fastener positions these vibrators use.
- Maintains Clamp Load Integrity — A worn or missing star washer allows fasteners to back out during operation, leading to loose assemblies, misalignment, and potential component damage. Replacing with the correct OEM piece restores full clamp load retention.
A star washer is a hardened locking washer with serrated teeth around its inner or outer edge. When a fastener is tightened, those teeth compress and dig into the mating surfaces, creating mechanical resistance that prevents the fastener from backing out under vibration. On concrete vibrators — which produce intense, continuous high-frequency vibration as part of their normal operation — keeping every fastener torqued and locked is critical to safe and consistent performance. A missing or worn star washer allows fasteners to gradually loosen, which can lead to rattling components, premature wear on surrounding parts, or loss of structural integrity in the assembly.
