The Wacker Neuson Pressure Filter is a genuine OEM pressure filter designed for the RD40-130 and RD45-140 tandem roller series, including standard, C, O, DPF, and US-spec variants. Sourced directly from Wacker Neuson, this is the exact part specified for these machines — no guesswork on fitment. It covers an extensive range of RD40-130 and RD45-140 configurations, making it the go-to replacement for fleet operators running multiple variants of these tandem rollers. When it's time to service the hydraulic system, the ensures you're installing the correct OEM-grade component every time.
Key Features
- OEM Filtration Integrity — Manufactured to Wacker Neuson's exact filtration specification, ensuring the correct micron rating and flow capacity for the hydraulic circuit in these tandem rollers.
- Direct-Fit Replacement — Matches the original mounting thread, port sizing, and bypass valve configuration for a straightforward swap during scheduled hydraulic maintenance.
- Broad RD Series Coverage — Confirmed fit across RD40-130 and RD45-140 variants including standard, C, O, DPF, and US-spec models across multiple serial number ranges.
- Protects Hydraulic Components — A functioning pressure filter catches contaminants before they reach sensitive hydraulic valves and motors; a clogged or failed filter accelerates wear throughout the entire system.
- Hydraulic System Safety — Maintaining a clean hydraulic circuit is critical to consistent drum drive and vibration control performance — a failed filter can lead to erratic machine behavior under load.
A pressure filter is a critical component in the hydraulic system of a tandem roller, tasked with removing particulate contamination from the pressurized fluid before it circulates through valves, pumps, and hydraulic motors. Keeping the fluid clean protects precision-clearance components from abrasive wear and maintains consistent pressure throughout the system. When a pressure filter becomes clogged or bypasses unfiltered fluid, hydraulic performance degrades — leading to uneven drum drive, loss of vibration output, and accelerated damage to downstream components.
