The Wacker Neuson is a genuine OEM Aft Motor A Steel Tube designed for the RD12A-90 and RD12-90 series tandem rollers. As a direct factory replacement, this steel tube is sourced and manufactured to the same specifications as the original component installed at the plant, ensuring a correct, trouble-free installation. It is confirmed compatible across multiple RD12-90 and RD12A-90 configurations, including solid ROPS and foldable ROPS variants. When you need to restore your tandem roller to full operating condition, part number is the correct OEM solution.
Key Features
- Genuine OEM Construction: — Fabricated to the same steel grade and dimensional tolerances as the original tube, ensuring a secure, leak-free connection at the aft motor.
- Direct Drop-In Replacement: — Matches original routing, diameter, and end fittings so the tube seats correctly without rework or adaptation to existing hydraulic connections.
- Broad RD12 Series Fitment: — Verified for the RD12A-90 and RD12-90 tandem rollers across solid ROPS and foldable ROPS configurations.
- Sustains Hydraulic Drive Integrity: — A sound steel tube maintains proper hydraulic flow to the aft drum drive motor; a cracked or corroded tube causes pressure loss, erratic drum speed, and compaction inconsistency.
- Hydraulic System Safety: — Replacing a damaged high-pressure steel tube with a genuine OEM part eliminates the risk of uncontrolled hydraulic fluid release, which presents a serious burn and fire hazard on live equipment.
The Aft Motor A Steel Tube is a rigid hydraulic line that carries pressurized fluid from the machine's hydraulic circuit to the drive motor powering the rear drum of the tandem roller. It is a structural conduit in the drivetrain circuit, and its integrity directly affects how consistently and evenly the rear drum rotates during compaction passes. When this tube develops a crack, corrosion pit, or fitting failure, hydraulic pressure drops, the aft drum loses consistent drive force, and the machine can leave uneven compaction patterns — or shut down entirely under low-pressure fault conditions. Replacing it promptly with the correct OEM part restores full hydraulic circuit performance and keeps the roller operating as intended.
