The Wacker Neuson is a genuine OEM Spark Plug ZGR5A designed for a range of Wacker Neuson gasoline-powered equipment, including the CRT36-24A ride-on trowel series, the RD12A-90 tandem roller, the RD11A and RD11AEC hydrostatic double drum vibratory rollers, and the BFS 2020AS floor saw. As a genuine OEM component, the is manufactured to the exact heat range, electrode gap, and thread specification required by these engines — no guesswork on compatibility. This spark plug is a direct drop-in replacement, restoring consistent ignition performance across every supported model. Keep a spare on hand to minimize unplanned engine downtime on the job.
Key Features
- Correct Heat Range, Guaranteed: — Manufactured to the OEM-specified heat range and electrode gap for the engines used across supported Wacker Neuson equipment, ensuring complete, consistent combustion on every cycle.
- Direct Drop-In Replacement: — Matches the original thread pitch, reach, and seat type so the plug installs cleanly into the cylinder head without modification or adapter.
- Broad Model Coverage: — A single part number serves the CRT36-24A ride-on trowel family, RD12A-90 tandem rollers, RD11A and RD11AEC double drum rollers, and the BFS 2020AS floor saw, simplifying parts stocking across your fleet.
- Restored Engine Starting and Power Delivery: — A fresh OEM-spec spark plug eliminates misfires, hard starting, and loss of power under load — common symptoms of a worn or fouled plug in high-cycle equipment engines.
- Ignition System Integrity: — Using the correct plug heat range prevents pre-ignition and electrode fouling, protecting the engine from damage caused by running a mismatched replacement plug.
A spark plug ignites the air-fuel mixture inside the engine's combustion chamber, triggering the controlled explosion that drives the piston and powers the machine. When a spark plug wears out, becomes fouled with carbon, or loses its gap specification, ignition becomes inconsistent — leading to rough running, hard starts, reduced power, and increased fuel consumption. In equipment like concrete trowels, tandem rollers, and floor saws — where engine responsiveness directly affects finish quality and productivity — maintaining a correctly functioning spark plug is essential to keeping the engine performing as intended.
