The Wacker Neuson Cooling Water Pipe is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, and O variants across both the original and.3 model generations. Sourced directly from Wacker Neuson, this part matches the factory-original specification for a direct, hassle-free installation. It is confirmed compatible across twelve distinct model configurations in the RD40-130 and RD45-140 families, making it the correct choice whether you are servicing an RD40-130 C, an RD45-140 O, or any of the.3-series successors.
Key Features
- Genuine OEM Fluid Routing Integrity — Manufactured to Wacker Neuson's exact internal diameter and connection tolerances, ensuring correct coolant flow rate through the engine cooling circuit without restriction or bypass.
- Direct Connection Fit — Engineered to mate with the factory coolant ports and clamp points on the RD40-130 and RD45-140 platforms, so installation follows the original service procedure without modification.
- Broad Series Coverage — A single part number covers twelve model configurations across the RD40-130 and RD45-140 families, including standard, C-series, O-series, and .3-generation variants.
- Protects Engine Operating Temperature — A correctly functioning cooling water pipe keeps coolant circulating at the designed rate, preventing thermal overload that can cause engine damage or forced shutdown mid-compaction job.
- OEM-Verified Part Number — Carrying part number 5100012175, this pipe is an authorized Wacker Neuson replacement, so you can order with confidence that you are receiving the correct component for your machine.
The cooling water pipe routes engine coolant between key points in the liquid cooling system of the tandem roller's power unit. By maintaining a sealed, unobstructed flow path, it allows the engine to shed heat effectively and hold a stable operating temperature across long compaction runs. A cracked, corroded, or leaking pipe disrupts that flow, leading to overheating, potential engine damage, and unplanned downtime on the job.
