Wacker Neuson 5000164816 Aft Motor B Steel Tube

The Wacker Neuson is a genuine OEM Aft Motor B Steel Tube designed for RD12A-90 and RD12-90 series tandem rollers. As a factory-sourced component, it meets the exact dimensional and material standards specified for these machines, ensuring a direct, hassle-free installation. The is confirmed compatible across multiple RD12A-90 and RD12-90 configurations, including solid ROPS and foldable ROPS variants. When you need a dependable structural tube to restore your roller's rear drive motor circuit, this is the part to spec.

Key Features

• Genuine OEM Steel Construction — Sourced directly from Wacker Neuson, this steel tube meets the wall thickness and material grade specified for the rear motor circuit on RD12-series rollers.
• Direct-Fit Replacement — Engineered to match the original routing and connection points of the Aft Motor B position, so the tube seats correctly without reworking fittings or brackets.
• Broad RD12 Series Coverage — Compatible with RD12A-90 (standard, double-drum green, and foldable ROPS) and RD12-90 (solid ROPS and foldable ROPS) tandem roller configurations.
• Maintains Hydraulic Circuit Integrity — A sound steel tube keeps fluid routed precisely to the aft drum drive motor, sustaining consistent compaction force and drum speed across asphalt and soil applications.
• Leak-Free Structural Support — Steel construction resists deformation under the hydraulic pressures and vibration loads common in walk-behind tandem roller operation, reducing the risk of circuit failure mid-job.

The Aft Motor B Steel Tube forms part of the hydraulic circuit that delivers pressurized fluid to the rear drum drive motor on the RD12-series tandem roller. By routing flow accurately to that motor, the tube directly influences the rear drum's rotational speed and compaction consistency — both critical on asphalt passes where uneven drum drive produces surface defects. A cracked, kinked, or corroded tube restricts flow or causes hydraulic leaks, which can result in loss of rear drum traction, uneven compaction, or a complete drive-circuit shutdown until the line is replaced.
