The Multiquip 798615 Spark Plug is a genuine OEM component designed for B46 series walk-behind power trowels. Sourced directly from Multiquip, this spark plug is the correct heat range and thread specification for the engine fitted to B46 equipment — no guesswork on compatibility. Keeping the correct OEM spark plug in your trowel ensures consistent ignition performance and protects against hard-start or misfiring issues during finishing work. DHS Equipment stocks the 798615 so you can get the right part and get back to work fast.
Key Features
- Correct Heat Range for the Application — OEM specification ensures the 798615 matches the engine's ignition timing and combustion requirements exactly, unlike generic plugs that may run too hot or too cold.
- Drop-In Engine Fitment — Correct thread pitch, reach, and gap spec for direct installation on B46 series trowels with no re-gapping or adapter required.
- Fits B46 Series Walk-Behind Trowels — Verified fitment for Multiquip B46 walk-behind power trowel equipment.
- Consistent Ignition, Consistent Finishing — A properly functioning spark plug delivers a strong, repeatable spark on every stroke, keeping the engine running smoothly through long concrete finishing sessions.
- Fuel System Protection — A worn or fouled plug causes incomplete combustion, leading to fuel washing cylinder walls and accelerating engine wear — replacing on schedule with the correct OEM part prevents this.
A spark plug ignites the air-fuel mixture inside the engine cylinder, providing the power stroke that keeps the engine running. In a walk-behind power trowel, the engine runs at sustained RPM under load, which means the plug is under constant thermal and electrical stress. A worn, fouled, or incorrect plug leads to misfires, hard starting, rough running, and increased fuel consumption — and on a finishing crew, an engine that won't run clean means flat work that won't wait.
