The Multiquip 31211PH9004 Brush Ar-13H is a genuine OEM component designed for a wide range of Multiquip equipment including AR13H, AR13HA, AR13HC, and AR14H rollers, the GA9.7HE gasoline-powered generator, and the JWN24HTCSL and JWN24HSCSL Whiteman ride-on power trowels. As a direct OEM replacement, 31211PH9004 is sourced and validated by Multiquip to meet the exact specifications of the original part. Sourcing the correct brush assembly is critical across these equipment families, where precise electrical contact and wear characteristics directly affect motor and charging system performance. DHS Equipment supplies this part ready for installation in any of the compatible models listed.
Key Features
- OEM Carbon Brush Grade: — Manufactured to the exact carbon compound and dimensional spec of the original, ensuring correct contact resistance and wear rate for sustained electrical output.
- Drop-In Replacement: — Matches the original brush holder dimensions and terminal connection on all compatible models, allowing straightforward swap-out during routine service.
- Broad Equipment Compatibility: — Fits AR13H, AR13HA, AR13HC, and AR14H rollers, GA9.7HE generators, and JWN24HTCSL and JWN24HSCSL ride-on trowels under a single part number.
- Sustained Motor Performance: — A properly seated brush maintains consistent current transfer to the armature; a worn or undersized brush causes arcing, heat buildup, and accelerated commutator wear.
- Electrical Safety Compliance: — Using the correctly rated OEM brush prevents overcurrent conditions and premature insulation breakdown in the motor windings.
A brush in an electric motor or generator acts as the sliding electrical contact that transfers current between the stationary wiring and the rotating armature or rotor. It rides against the commutator or slip ring and wears gradually over time — this is normal and expected. When a brush wears down too far, electrical contact becomes intermittent, causing loss of power output, excessive sparking at the commutator, and accelerated damage to both the commutator surface and the motor windings. Replacing the brush on schedule with a correctly specified OEM part like the Multiquip 31211PH9004 keeps the motor running cleanly and protects the more expensive components around it.
