Wacker Neuson 5000163986 RD16 X Motor After Drain to T Hose

The Wacker Neuson is a genuine OEM RD16 X Motor After Drain to T Hose designed for the RD16-90 tandem roller series and CB14B soil and asphalt compaction rollers. As a direct OEM part, is manufactured to the exact routing, diameter, and connection specifications of the original hydraulic drain line, ensuring a proper seal and correct fluid return flow without adaptation. This hose serves machines across multiple configuration variants of the RD16-90 and CB14B-900 and CB14B-1000 series. Keeping the correct drain hose in service is essential for protecting the hydraulic motor and maintaining the integrity of the closed-loop hydrostatic drive system on these tandem rollers.

Key Features

• Genuine OEM Hydraulic Hose Construction — Built to the same pressure rating, inner diameter, and end-fitting configuration as the factory original, ensuring a leak-free drain path from the motor.
• Direct-Fit Routing for RD16-90 and CB14B Platforms — Engineered to follow the original hose path between the motor drain port and the T-fitting junction with no re-routing or adapter fittings required.
• Broad Fitment Across Roller Variants — Compatible with RD16-90 Vibratory Roller, Hydrostatic Vibratory Roller (IRH), and RD16-90 Tandem Roller configurations, as well as CB14B-900 and CB14B-1000 soil and asphalt compaction rollers.
• Protects Hydraulic Motor Longevity — A functioning drain line maintains correct back-pressure at the motor case drain; a cracked or failed hose can cause case pressure buildup leading to motor seal failure and costly hydraulic repairs.
• Hydraulic System Integrity — Correct drain line specification is critical in hydrostatic drive circuits; using the proper OEM hose prevents contamination ingestion and maintains rated system pressure at the T-junction.

The motor after drain hose carries low-pressure hydraulic fluid away from the hydrostatic drive motor's case drain port and routes it back into the return circuit via a T-fitting junction. In a hydrostatic drive system like those found on tandem rollers, keeping the motor case drain clear and unobstructed is critical — excessive back-pressure at the case drain will force fluid past the motor shaft seals, leading to external leaks and eventual motor failure. When this hose cracks, collapses, or leaks at a fitting, operators may notice sluggish drum drive response, hydraulic fluid loss, or overheating in the drive circuit, all of which point to a compromised drain path that needs immediate attention.
