The Wacker Neuson 5100011913 is a genuine OEM Oil Cooler designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this part matches the original component specification for a direct, hassle-free installation. It fits an extensive range of RD40-130 and RD45-140 variants, including standard, combination (C), offset (O), DPF-equipped, and.3-series configurations across US and international builds. Verifying your machine's model number against the fitment list before ordering ensures you receive the correct part for your roller.
Key Features
- Genuine OEM Thermal Management: — Engineered to the exact flow rate and heat-rejection capacity of the original, ensuring hydraulic oil temperatures stay within the operating range your roller was designed for.
- Drop-In Installation: — Matches original port sizing, bracket mounting points, and line connections on the RD40-130 and RD45-140 platforms, so installation follows the standard service procedure without fabrication or adaptation.
- Broad RD-Series Fitment: — Compatible with RD40-130 and RD45-140 variants including C, O, DPF, .3, and US-spec models, covering walk-behind tandem rollers across multiple production runs.
- Protects Hydraulic System Integrity: — A functioning oil cooler prevents heat-related viscosity breakdown in hydraulic fluid, maintaining consistent drum drive and vibration performance across extended paving or compaction runs.
- Backed by Wacker Neuson OEM Standards: — As a genuine OEM part, the 5100011913 meets the same material and construction criteria as the unit that came off the production line, giving you confidence in the replacement.
The oil cooler is responsible for dissipating heat from the hydraulic fluid that powers the drum drive, vibration system, and steering functions on your tandem roller. During heavy compaction work, hydraulic fluid temperatures rise steadily, and without effective cooling, the fluid degrades rapidly — leading to sluggish drum response, erratic vibration output, and accelerated wear across seals and hydraulic components. A failed or restricted oil cooler can push fluid temperatures beyond safe limits quickly, so replacing a damaged unit promptly with a correctly rated component like the Wacker Neuson 5100011913 is essential to keeping your RD40-130 or RD45-140 performing as intended.
