Wacker Neuson 5000163993 Pump Port T to Filter Hose RD16

The Wacker Neuson is a genuine OEM Pump Port T to Filter Hose RD16 designed for the RD16-90 and RD16-100 tandem vibratory rollers and the CB14B series soil and asphalt compaction rollers. As a direct Wacker Neuson OEM part, is manufactured to the same specifications as the original, ensuring a correct connection between pump port T and the hydraulic filter without modification. This hose serves multiple machine configurations across the RD16 and CB14B families, making it a reliable choice for operators and service technicians working across a mixed fleet of Wacker Neuson rollers.

Key Features

• Genuine OEM Hydraulic-Grade Construction — Built to Wacker Neuson's original pressure and temperature tolerances for the hydraulic circuit, not a generic hose substitute.
• Correct Port T Routing — Engineered specifically to connect pump port T to the hydraulic filter housing, matching the exact routing path and end fittings of the original installation.
• Broad RD16 and CB14B Fitment — Compatible with RD16-90 and RD16-100 tandem rollers as well as CB14B-900 and CB14B-1000 soil and asphalt compaction variants.
• Leak-Free Hydraulic Return Path — A compromised or cracked return hose allows hydraulic fluid loss and contamination; this OEM replacement restores a fully sealed circuit and keeps the hydrostatic drive system operating at correct pressure.
• Fuel-System and Hydraulic Safety Integrity — Hydraulic hose failures on compaction equipment can result in fluid spray near hot surfaces; replacing with the correct OEM hose maintains the integrity of the sealed system and reduces that risk.

The Pump Port T to Filter Hose RD16 is a hydraulic return-side hose that carries fluid from port T on the hydrostatic pump back to the hydraulic filter before the fluid re-enters the reservoir and drive circuit. On tandem rollers like the RD16-90 and RD16-100, the hydrostatic drive system powers both drum rotation and propulsion, so maintaining clean, uninterrupted fluid flow through this hose is critical to consistent compaction performance and smooth machine travel. When this hose deteriorates — through cracking, abrasion, or fitting failure — it can cause hydraulic fluid loss, pressure drop in the drive circuit, and potential filter bypass, all of which lead to erratic drum behavior and accelerated wear on the pump and motor.
