The Wacker Neuson 5100023672 Heater Plug is a genuine OEM component designed for the RC50 and RC70 series single-drum soil compactors. As a direct OEM replacement, part 5100023672 is produced to the same specifications as the original, ensuring consistent cold-start performance across the full RC50 and RC70 model range — including standard, padfoot, DPF CAB, DPF ROPS, VO, and US-spec variants. Sourced directly through the Wacker Neuson OEM supply chain, this heater plug is the correct choice for operators and service technicians who need a verified, no-guesswork repair.
Key Features
- Genuine OEM Heating Element Integrity — Manufactured to the original resistance and heat output specification, so the glow element reaches operating temperature in the correct pre-heat window every time.
- Drop-In Thread and Connector Match — Shares the exact thread pitch, reach, and electrical connector as the factory-installed unit, allowing straightforward removal and installation without modification to the engine block or wiring harness.
- Broad RC-Series Coverage — Compatible with the full RC50 and RC70 compactor family, including RC50, RC50p, RC50P, RC70, RC70p, RC70P, RC70vo in standard, DPF CAB, DPF ROPS, and US-spec configurations.
- Dependable Cold-Start Protection — A fully functional heater plug pre-warms the combustion chamber so the diesel engine fires cleanly in cold or damp conditions; a failed plug leads to hard starts, white smoke, and incomplete combustion.
- Fuel System Safety Relevance — Correct heater plug operation prevents unburned fuel from accumulating in the cylinder during repeated failed start attempts, protecting the engine and reducing exhaust emissions at startup.
A heater plug — commonly called a glow plug — is a small electric heating element threaded directly into the pre-combustion or combustion chamber of a diesel engine. Before the engine cranks, the plug heats the air in the chamber to a temperature high enough for the diesel fuel to ignite reliably, which is especially critical when ambient temperatures are low. When a heater plug fails or loses output, the engine may crank without firing, produce excessive white smoke on startup, or run rough until fully warmed — all signs that replacement is needed to restore normal operation.
