The Wacker Neuson Drain Set Screw is a genuine OEM component designed for a broad range of Wacker Neuson equipment, including RD12A tandem rollers, CRT36 and CRTv36 ride-on concrete trowels, GP, GPS, GV, and GS series portable generators, and the BFS 2020AS floor saw. As a factory-sourced part, the is manufactured to the same specifications as the original hardware installed during production, ensuring a consistent, trouble-free fit across all listed applications. Whether you are servicing a generator on a power-critical jobsite or maintaining a ride-on trowel between concrete pours, using the correct drain set screw protects threads and prevents fluid loss. Verify your model number against the fitment list before ordering to confirm compatibility with your specific machine configuration.
Key Features
- Genuine OEM Thread Integrity — Sourced directly from Wacker Neuson, this set screw is machined to the exact thread pitch and torque spec of the original, eliminating the stripped-thread risk that comes with improperly sized hardware.
- Direct-Swap Replacement — Installs into the existing drain port without reworking the bore or fitting an adapter; the seating geometry matches the factory drain passage.
- Broad Cross-Family Fitment — A single part number covers RD12A tandem rollers, CRT36 and CRTv36 ride-on trowels, GP / GPS / GV / GS portable generators, and the BFS 2020AS floor saw, making it a practical stocking item for mixed fleets.
- Leak-Free Drain Sealing — A correctly seated drain set screw maintains a positive seal on oil and fluid drain passages; a worn or cross-threaded screw allows slow seepage that can lead to low fluid levels and accelerated wear on internal components.
- Fluid System Safety — On generators and rollers, an improperly sealed drain point risks uncontrolled fluid release near hot engine surfaces; using the correctly rated OEM hardware keeps the drain closure within the designed pressure and temperature range.
A drain set screw seals the drain port on an engine or fluid reservoir, holding oil, coolant, or other operating fluids securely inside the machine between service intervals. It is removed during scheduled fluid changes to allow the sump or reservoir to empty completely, then reinstalled to restore the sealed system. When a drain set screw is damaged, cross-threaded, or missing, the machine loses fluid integrity — resulting in slow leaks, unexpected low-fluid conditions, and potential engine or hydraulic damage if the loss goes undetected.
