The Multiquip 11437179040 is a genuine OEM Brush Negative designed for a range of Multiquip equipment including the MDR-9DYE power trowel, MVH-200DA2, MVH-304DSB, MVH-306D, MVH-306DS, MVH-306DS2, MVH-402DSB, and MVH-406DSY reversible plate compactors, as well as the MRH-800DS and MRH800DS2 walk-behind rollers. As a direct OEM replacement, this brush is manufactured to the same electrical specifications as the original component, ensuring correct contact pressure and conductivity within the machine's motor. Sourced directly through authorized Multiquip supply channels, part 11437179040 is the correct replacement when the original brush shows wear, reduced output, or visible damage. DHS Equipment stocks this part to keep your equipment back in service with the right component the first time.
Key Features
- Correct Electrical Contact Grade — OEM-spec carbon brush material ensures proper current transfer and consistent motor brush performance across operating cycles.
- Drop-In Motor Brush Replacement — Matches original brush dimensions and terminal configuration for straightforward installation into the motor brush holder.
- Broad Equipment Compatibility — Fits the MDR-9DYE, MVH series reversible plate compactors (MVH-200DA2 through MVH-406DSY), and MRH-800DS and MRH800DS2 walk-behind rollers.
- Sustained Motor Output — A worn or undersized brush causes arcing, heat buildup, and loss of motor power; replacing with a correctly rated brush restores full motor efficiency.
- Genuine OEM Part — Supplied as original equipment, so the brush profile, spring tension rating, and carbon compound match what the motor was engineered to run on.
The Brush Negative is a carbon brush that rides against the commutator inside the electric motor, completing the circuit that allows current to flow and the motor to generate torque. As the brush wears down over time, contact area decreases, leading to increased electrical resistance, arcing at the commutator surface, reduced motor power, and eventually motor failure. Replacing the brush at the correct service interval — or at the first sign of sparking or power loss — protects the commutator from damage and keeps the motor running at full rated output.
