The Wacker Neuson Oil Cooler is a genuine OEM component designed for the RD24-100 and RD27-120 series tandem rollers, including standard, c, o, and e variants across multiple production generations. Sourced directly from Wacker Neuson, this part meets the same specifications as the original unit installed at the factory — no guesswork on fitment or compatibility. The covers an extensive range of RD series models, making it the correct choice for operators running RD24 and RD27 platforms in standard, padfoot, offset, and electric configurations.
Key Features
- Genuine OEM Thermal Performance — Engineered to Wacker Neuson's original heat-dissipation specification, ensuring the hydraulic system stays within safe operating temperatures under continuous compaction loads.
- Direct Drop-In Replacement — Matches the original mounting configuration and port connections of the RD24-100 and RD27-120 series, allowing straightforward installation without bracket or line modifications.
- Broad RD Series Compatibility — Fits RD24-100 and RD27-120 tandem rollers across standard, c (padfoot), o (offset), and e (electric) variants, spanning multiple production series including .3 and e-generation machines.
- Protects Hydraulic System Integrity — A functioning oil cooler prevents heat buildup that causes hydraulic fluid degradation, seal failure, and pump damage — keeping your roller's drive and vibration circuits operating correctly.
- Verified OEM Part Number — Part number 5100011996 is the authoritative Wacker Neuson reference for this application, so you can order with confidence that the correct part will arrive.
The oil cooler is responsible for drawing heat out of the hydraulic fluid as it circulates through the roller's drive and vibration systems. Tandem rollers generate significant hydraulic heat during sustained compaction work, and without effective cooling, fluid temperatures rise to levels that accelerate wear on pumps, motors, and seals throughout the circuit. When an oil cooler becomes blocked, leaks, or loses efficiency, the machine will typically show rising hydraulic temperatures, reduced drive response, and eventually trigger thermal protection shutdowns — replacing the cooler promptly restores full system capacity and protects the broader hydraulic circuit from heat-related damage.
