The Multiquip 30510ZDX003 Ignition Coil MD105 is a genuine OEM ignition coil designed for the MD105 mid-sized hydraulic ride-on power trowel. Sourced directly from Multiquip, this coil delivers the precise spark timing and output voltage required to keep the engine starting reliably and running at full power. Confirm your model against part number 30510ZDX003 before ordering to ensure a direct, correct-fit installation.
Key Features
- Genuine OEM Spark Output — Wound and calibrated to the exact primary and secondary resistance specs of the original coil, ensuring consistent ignition energy at every firing event.
- Direct-Fit for MD105 — Engineered specifically for the MD105 hydraulic ride-on power trowel, mounting to the existing bracket and connector positions without alteration.
- Consistent Cold and Hot Starting — Correct coil output supports reliable engine starts across a full range of ambient temperatures and operating conditions on the pour.
- Protects Ignition System Components — A coil operating within spec prevents voltage spikes that can damage spark plugs, wiring, and control modules over time.
- Fuel System Efficiency — Properly timed, full-strength spark ensures complete fuel combustion, maintaining fuel efficiency and preventing fouled plugs during extended finishing runs.
The ignition coil transforms low-voltage current from the engine's charging circuit into the high-voltage pulse needed to fire the spark plug and ignite the air-fuel mixture in the combustion chamber. On a ride-on trowel like the MD105, a strong and consistent spark is essential — the engine must maintain steady RPM to keep the hydraulic system delivering smooth, predictable blade pressure across the slab. When an ignition coil begins to fail, symptoms typically include hard starting, misfires under load, and rough or inconsistent engine idle, all of which directly affect finishing quality and operator control.
