The Wacker Neuson Water Pump is a genuine OEM water pump designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory — no guesswork on fit or function. Compatible across the RD40-130, RD40-130C, RD40-130O, RD45-140, RD45-140C, and RD45-140O tandem roller variants, the is the correct replacement whether you're servicing a standard, C, or O configuration machine. Keep your roller's cooling system operating at full capacity with the right part the first time.
Key Features
- Genuine OEM Cooling Integrity — Built to the same flow rate and pressure tolerances as the original, ensuring the engine cooling circuit performs exactly as engineered.
- Drop-In Replacement — Matches the original mounting points, port sizes, and drive interface of the factory water pump for a straightforward swap during scheduled maintenance or emergency repair.
- Broad RD Series Coverage — Fits the full RD40-130 and RD45-140 tandem roller family, including standard, C, and O variants, covering six model configurations with a single part number.
- Sustained Engine Temperature Control — A correctly functioning water pump keeps coolant circulating at the right rate; a worn or failing pump leads to overheating, thermal shutdown, and potential engine damage on the job.
- Verified Wacker Neuson Part Number — The 5100025013 is the OEM-assigned part number for this application, so you can order with confidence that you're receiving the exact replacement Wacker Neuson specifies.
The water pump is responsible for circulating coolant through the engine's cooling system, drawing heat away from the cylinder head and engine block to maintain safe operating temperatures. On a tandem roller working in demanding compaction applications, consistent thermal management is critical — the engine runs hard and heat builds quickly. When the water pump wears out, coolant flow drops, engine temperatures rise, and the machine will either trigger a thermal protection shutdown or, if left unchecked, sustain serious internal engine damage. Replacing a failing water pump promptly with a genuine OEM part like the Wacker Neuson 5100025013 restores proper coolant circulation and protects the engine investment in your roller.
