The Wacker Neuson Cross Fitting is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O,.3, and DPF variants. Sourced directly from Wacker Neuson, this part matches the original specification fitted at the factory, ensuring a correct installation without guesswork. It covers an extensive range of RD-series machines, making it the go-to replacement for fleet operators running multiple roller configurations.
Key Features
- OEM-Grade Flow Path Integrity — Manufactured to Wacker Neuson's original dimensional tolerances, ensuring internal passage alignment and leak-free sealing at every port connection.
- Direct Drop-In Replacement — Matches the original thread spec and port orientation of the 5100071895, so the fitting seats and torques correctly without reworking adjacent lines or fittings.
- Broad RD-Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across standard, C, O, .3, and DPF configurations, covering eighteen distinct machine variants in a single part number.
- Sustained System Pressure — A correctly functioning cross fitting maintains consistent fluid routing across connected circuits; a failed or cracked fitting can cause pressure loss, fluid leaks, and compromised roller operation on the compaction pass.
- Genuine OEM Assurance — Carries full Wacker Neuson OEM provenance, meaning the part has been validated for use in these machines and meets the same material and dimensional standards as the original.
A cross fitting is a four-way junction used within a machine's hydraulic or fluid circuit to route flow from a single supply line to multiple branches simultaneously. It acts as a distribution point, keeping fluid pressure balanced across connected lines. When a cross fitting cracks, corrodes, or develops a failed seal at any one of its ports, the result is fluid loss, pressure drop across the affected circuit, and potential damage to downstream components — all of which can bring a compaction operation to a halt.
