The Wacker Neuson is a genuine OEM Glow Plug designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers, including both standard and Traction Control configurations. As a factory-sourced component, part is manufactured to the exact specification required by the RD27 series diesel engine, ensuring correct heat output and thread fitment right out of the box. This plug covers a wide range of RD27 build variants, so verify your machine number against the fitment list to confirm compatibility before ordering.
Key Features
- Correct Heat Output for Cold-Start Reliability — Engineered to the OEM heat rating for the RD27 series diesel engine, delivering consistent pre-heat performance in cold or damp conditions.
- Direct Thread-In Replacement — Matches the factory thread pitch and tip diameter, so installation goes straight into the existing cylinder head port without modification.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 Hydrostatic Vibratory Rollers across multiple build variants, including standard and Traction Control models.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this component meets the same material and electrical resistance specifications as the part installed at the factory.
- Protects Engine Starting System — A correctly functioning glow plug reduces stress on the starter motor and battery by bringing cylinder temperatures up to ignition threshold quickly, preventing hard starts and excessive cranking.
A glow plug is a electrically heated element threaded into the pre-combustion or combustion chamber of a diesel engine. When you turn the key, current flows through the plug and heats the tip to a high temperature, warming the air-fuel mixture enough for reliable ignition — especially critical in cool weather or after extended shutdown. On a tandem roller like the RD27 series, a failed or weak glow plug shows up as hard starting, excessive white smoke on start-up, or repeated no-start conditions; left unaddressed, repeated over-cranking can accelerate wear on the starter motor and drain the battery. Replacing a worn plug with the correct OEM unit, Wacker Neuson 5000161447, restores fast, clean cold-starts and keeps the machine ready to work from the first turn of the key.
