The Multiquip CM20720 Brush Set 110V CX40A 60A 600HF is a genuine OEM replacement designed for CX40A series concrete pumps. As a direct Multiquip OEM component, CM20720 is manufactured to the same specifications as the original, ensuring correct carbon grade, brush geometry, and contact pressure for the motor it serves. This brush set is confirmed for the CX40A and is also referenced for CX40A, 60A, and 600HF pump applications, making it a dependable choice when servicing these cycloidal-driven concrete pumps.
Key Features
- Correct Carbon Grade for Motor Brushes — Matched carbon compound and dimensions ensure proper electrical conductivity and commutator contact specific to 110V motor configurations.
- Genuine OEM Component — Sourced directly from Multiquip, this brush set carries the same part specification as the original installed unit, with no substitution or compromise in material grade.
- Direct-Fit Replacement — Engineered to drop into the brush holders of the CX40A motor assembly without recutting or reshaping, maintaining proper spring tension and seating from first use.
- Confirmed Fitment — Compatible with CX40A, CX60A, and CX600HF concrete pump models, covering a range of cycloidal-driven Multiquip pump units in this series.
- Protects Motor Longevity — Worn or undersized brushes cause arcing, commutator scoring, and eventual motor failure; replacing with this part restores clean electrical transfer and prevents accelerated wear on surrounding motor components.
Carbon motor brushes are the sliding electrical contacts that transfer current between the stationary wiring and the rotating commutator inside an electric motor. On concrete pumps like the CX40A series, the drive motor depends on consistent brush contact to maintain smooth, uninterrupted operation under load. As brushes wear down over time, electrical resistance increases, causing heat buildup, reduced motor output, and eventually stalling or motor damage. Replacing the brush set with the correct Multiquip CM20720 unit restores full electrical contact, keeps the motor running at rated output, and extends the service life of the motor as a whole.
