The Wacker Neuson 5100042312 is a genuine OEM Glow Plug designed for the DPU-series diesel reversible vibratory plate compactors, including the DPU80, DPU90, DPU110, and DPU130 model families. As a factory-sourced component, this glow plug is manufactured to the exact specifications required by Wacker Neuson for reliable cold-start ignition in diesel-powered compaction equipment. This part also fits the HTC15 trench roller, making it a widely applicable diesel engine service item across multiple Wacker Neuson machine families. Keeping a verified OEM replacement on hand ensures your machine starts cleanly and stays on the job when temperatures drop.
Key Features
- Genuine OEM Heat Output Spec — Manufactured to Wacker Neuson's exact resistance and temperature rating, ensuring the glow plug reaches the correct pre-heat level for reliable diesel ignition.
- Direct Swap for the Original — Matches the original thread pitch, tip diameter, and electrical connector of the factory glow plug for a straightforward service replacement.
- Broad DPU-Series Coverage — Confirmed fitment across DPU80, DPU90, DPU110, and DPU130 reversible plate compactor models, as well as the HTC15 trench roller, covering a wide range of diesel-powered Wacker Neuson equipment.
- Cold-Start Performance — A functioning glow plug brings combustion chamber air up to ignition temperature before cranking, enabling fast, clean starts even in cold or damp jobsite conditions.
- Fuel System Safety — A failed glow plug can cause hard starting, excessive cranking, raw fuel injection without ignition, and unburned fuel accumulation — replacing it promptly protects the engine and the operator.
A glow plug is a small electric heating element threaded directly into the diesel engine's combustion chamber. Before the engine cranks, the glow plug heats the compressed air inside the cylinder to a temperature high enough to ignite diesel fuel, which does not use a spark ignition system. When a glow plug fails or loses output, the engine becomes difficult or impossible to start in cold conditions, cranks excessively, and may produce white smoke from unburned fuel passing through the cylinder. Replacing a worn glow plug with a correctly spec'd OEM part restores proper cold-start performance and protects the engine from the wear caused by prolonged cranking and incomplete combustion.
