The Wacker Neuson Banjo is a genuine OEM component designed for the RD40-130 and RD45-140 tandem roller series, including standard, combination (c), offset (o), and DPF-equipped variants. As a direct OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit within the hydraulic circuit of your machine. This part covers an extensive range of RD-series configurations, so confirm your model number before ordering to ensure compatibility with your specific roller. Keeping the fluid circuit intact with a properly functioning banjo fitting is essential to maintaining consistent hydraulic flow and overall machine performance.
Key Features
- Genuine OEM Fluid Passage Integrity — Manufactured by Wacker Neuson to the same tolerances as the original, maintaining correct flow rate and seal-seat geometry specific to hydraulic banjo fittings.
- Direct-Swap Installation — Matches the original port thread size and bolt-through design, allowing straightforward removal and reinstallation without reworking hydraulic line connections.
- Broad RD-Series Coverage — Compatible with RD40-130 and RD45-140 tandem rollers across standard, combination, offset, DPF, and .3-generation model variants.
- Sustained Hydraulic Flow — A correctly seated banjo fitting prevents restricted or contaminated flow in the hydraulic circuit; a cracked or failed fitting can cause pressure loss and erratic drum operation.
- Fuel and Hydraulic System Safety — Banjo fittings carry pressurized fluid; using a genuine OEM part with correct thread engagement helps prevent leaks that could pose a fire or slip hazard on the worksite.
A banjo fitting is a hollow, bolt-through hydraulic connector that allows fluid to pass from a line or hose into a component port at an angle — named for its rounded, instrument-like shape. It works alongside a sealing washer on each face to contain pressurized hydraulic fluid and direct it where it needs to go within the system. When a banjo fitting cracks, strips, or develops a compromised seal surface, hydraulic fluid can leak, causing pressure drops that affect drum vibration consistency and roller steering response.
