Multiquip 8001-043 Armature and Bearing Assembly 115V 3HP SVA-3

The Multiquip 8001-043 is a genuine OEM Armature and Bearing Assembly 115V 3HP SVA-3 designed for Multiquip concrete vibrator models CV1A, CV2A, CV2B, CV3A, and CV3B. As a direct OEM replacement, this assembly is sourced from Multiquip to ensure correct electrical characteristics, dimensional fit, and bearing tolerancing for the SVA-3 motor unit. Keeping this assembly in serviceable condition is critical to sustained vibrator output — a worn or damaged armature will result in reduced motor efficiency, overheating, or complete motor failure. Trust the 8001-043 to restore your vibrator to full operating performance.

Key Features

• Correct Electrical Specification: — Wound and rated to the exact 115V, 3HP output spec of the SVA-3 motor, ensuring proper current draw and motor performance without risk of underperformance or overload.
• Integrated Bearing Assembly: — Supplied as a complete armature and bearing unit, allowing a single-component swap that restores both rotational accuracy and electrical output in one service step.
• Genuine OEM Sourcing: — Manufactured to Multiquip's original production standards, this part carries the same material and tolerance specifications as the component installed at the factory.
• Confirmed Fitment: — Verified for use with Multiquip concrete vibrator models CV1A, CV2A, CV2B, CV3A, and CV3B — cross-reference part number 8001-043 before ordering.
• Restores Full Vibration Output: — A correctly functioning armature delivers consistent motor torque to the vibrator head, allowing the operator to consolidate concrete evenly and eliminate voids. A failed armature causes erratic or zero vibration output.
• Electrical Safety Compliance: — Using the correct OEM-specified armature assembly in an electric-powered vibrator maintains proper insulation class and motor protection, reducing the risk of electrical fault in wet or demanding job conditions.

The armature is the rotating core of an electric motor — it carries the wound conductors that interact with the stator's magnetic field to generate rotational torque. In a concrete vibrator, that torque drives the eccentric weight or flex-shaft that produces the high-frequency vibration needed to consolidate freshly poured concrete. The bearing assembly supports the armature shaft, maintaining precise concentricity during rotation. When the armature windings degrade or the bearings wear, the motor loses efficiency, generates excess heat, and will ultimately seize or burn out — leaving the vibrator inoperable at the point it is needed most.
