The Multiquip 21E79430J1 Ignition Coil Complete is a genuine OEM component designed for MTX-series rammers including the MTX60SD, MTX60SF, MTX70SD, MTX80SD, and MTX80SF. This is a direct OEM replacement sourced through Multiquip's authorized parts network, ensuring the coil meets the exact output and resistance specifications required by these machines. If your rammer is misfiring, failing to start, or losing spark under load, the part is the correct OEM replacement to restore full ignition performance. DHS Equipment stocks this part to keep your compaction equipment running at full capacity on the jobsite.
Key Features
- Correct Ignition Output Spec — Genuine OEM coil matched to the precise spark energy and resistance values required by MTX-series rammer engines, not a generic substitute.
- Drop-In Replacement — Mounts directly to the engine housing using the original mounting points, with no rework to wiring or brackets needed.
- Broad MTX-Series Fitment — Compatible with MTX60SD, MTX60SF, MTX70SD, MTX80SD, and MTX80SF rammers, covering a wide range of Multiquip tamper models in a single part number.
- Consistent Spark Under Load — A properly functioning ignition coil delivers a strong, consistent spark throughout the full compaction stroke cycle, maintaining engine power and stroke rate.
- Ignition Safety Integrity — An OEM coil with the correct kill-circuit response ensures the engine stops reliably when the operator releases the safety switch — critical for rammer operation.
The ignition coil generates the high-voltage electrical pulse that fires the spark plug at the correct moment in the engine's cycle. On a rammer like the MTX-series, the engine must maintain consistent ignition timing under the sustained vibration and mechanical stress of compaction work — conditions that accelerate wear on ignition components. When the coil begins to fail, the engine may become difficult to start, run roughly, misfire at operating temperature, or cut out entirely under load. Replacing a worn coil with a genuine Multiquip 21E79430J1 restores the correct spark energy and timing, bringing the rammer back to full operating performance.
