The Multiquip 21E79230J1 Flywheel Complete is a genuine OEM component designed for MTX60SD, MTX60SF, MTX70SD, MTX80SD, and MTX80SF series rammers. Sourced directly from Multiquip, this flywheel assembly ensures the correct fit, balance, and timing characteristics the MTX rammer family demands. If your machine is showing signs of rough running, loss of power, or erratic compaction strokes, the flywheel is a key component to inspect and replace with an exact OEM unit. DHS Equipment stocks this part to keep your crew working without extended delays.
Key Features
- Genuine OEM Rotational Balance — Manufactured to the precise mass and balance tolerances required for smooth high-frequency rammer operation, preventing vibration imbalance that can stress the crankshaft and engine mounts.
- Direct OEM Assembly Fit — Engineered to mount directly to the crankshaft of MTX-series rammers using the original hardware positions, requiring no rework to the engine assembly.
- Broad MTX Rammer Compatibility — Confirmed fitment across five MTX rammer models: MTX60SD, MTX60SF, MTX70SD, MTX80SD, and MTX80SF.
- Consistent Ignition Timing — The flywheel carries the magneto trigger used by the ignition system; a worn or damaged flywheel can cause misfires, hard starting, and inconsistent compaction stroke cycles.
- Complete Assembly — Supplied as a complete flywheel unit, so the full rotating mass and integrated components are renewed in a single replacement.
The flywheel on a rammer serves as the rotating energy store that keeps the engine running smoothly between power strokes and drives the magneto to generate ignition spark. On MTX-series tampers, the flywheel also carries the magnetic trigger that fires the ignition coil at the correct moment — if the flywheel becomes cracked, corroded, or out of balance, the engine will misfire, lose power, or fail to start altogether. Replacing a worn flywheel with a genuine OEM Multiquip 21E79230J1 Flywheel Complete restores proper engine rhythm, consistent ignition timing, and the strong, steady compaction stroke that MTX rammers are built to deliver.
