The Wacker Neuson 5100012234 is a genuine OEM Hydraulic Oil Tank designed for the RD18 series tandem rollers, including the RD18-80, RD18-100, and RD18-100c model families. As a direct OEM replacement, this tank is manufactured to the same standards as the original component and drops into the hydraulic system without modification. It is compatible across a wide range of RD18 configurations, covering SE, US, and standard variants as well as the updated.3 series machines. Confirm your machine's model number before ordering to ensure correct fitment.
Key Features
- Genuine OEM Construction — Manufactured to the same material and dimensional specifications as the original tank, ensuring proper wall integrity, port placement, and sealing surfaces that aftermarket alternatives may not replicate.
- Direct Bolt-In Replacement — Mounting points, hydraulic line connections, and fittings align with the original installation on RD18 series tandem rollers, allowing a straightforward swap during service.
- Broad RD18 Series Compatibility — Fits RD18-80, RD18-100, and RD18-100c variants including SE, US, standard, and .3 series configurations across multiple machine numbers.
- Protects Hydraulic System Integrity — A properly sealed and undamaged reservoir maintains correct fluid volume and prevents contamination, keeping the hydraulic drive and vibration systems operating at full capacity.
- Leak Prevention and System Pressure — A cracked or failed tank causes fluid loss, pressure drop, and potential pump or motor damage; replacing with a correctly rated OEM tank eliminates that risk at the source.
The hydraulic oil tank serves as the reservoir for the fluid that powers the RD18's drive system, steering, and drum vibration mechanisms. It stores hydraulic oil at the correct volume and pressure, feeds the pump, and accepts return fluid from the circuit — keeping the entire system primed and operational. When the tank cracks, leaks, or becomes contaminated through damage to the reservoir walls or fittings, hydraulic pressure drops and the roller loses drive force or vibration performance, which can bring compaction work to a halt and risk costly downstream damage to pumps and motors.
