The Multiquip EM904 Countershaft Flange is a genuine OEM component designed for a wide range of Multiquip and Whiteman equipment families, including HTN-series ride-on trowels, MVC and MVH plate compactors, MTX rammers, AR-series rollers, WM and MC mixers, QP pumps, GA generators, GAW welders, and SP and MP masonry saws. As a direct OEM replacement sourced through the Multiquip parts network, the EM904 meets the original engineering specification for every listed application. Verified fitment spans models including MVC82VHW, MVC82VH, MTX70HDR, MTX80HDR, AR13H, AR14H, WM70S/P, MC94P/S, and many others across the Multiquip portfolio. When you need a countershaft flange that installs correctly the first time, the EM904 is the part to order.
Key Features
- Genuine OEM Dimensional Accuracy — Machined to the original countershaft interface specification, ensuring correct bore alignment, seating, and torque transfer without reworking mating components.
- Direct-Install Compatibility — Matches the original mounting pattern and shaft interface, allowing straightforward installation without modification across every listed application.
- Broad Multi-Family Fitment — Confirmed for HTN ride-on trowels, MVC and MVH plate compactors, MTX rammers, AR rollers, WM and MC mixers, GA generators, GAW welders, QP pumps, and SP and MP saws.
- Maintains Drivetrain Integrity — A correctly fitted countershaft flange preserves proper power transmission alignment; a worn or failed flange can cause shaft wobble, accelerated bearing wear, and loss of drive efficiency.
- Single Part Number Across Multiple Platforms — The EM904 serves as a shared OEM component across diverse Multiquip equipment lines, simplifying parts inventory for mixed fleets.
A countershaft flange is a precision-machined collar or mounting face that secures the countershaft within the drivetrain assembly and transfers rotational force between driving and driven components. It keeps the shaft centered and axially retained so that gears, pulleys, or couplings remain in correct alignment during operation. When this flange wears, cracks, or becomes loose, the countershaft can shift position, causing vibration, uneven power delivery, and accelerated wear on adjacent bearings and drive components — ultimately leading to drivetrain failure if left unaddressed.
