The Wacker Neuson is a genuine OEM Diode Assembly designed for the CRT36-24A ride-on trowel series, RD12A-90 tandem rollers, and the BFS 2020AS floor saw. As a factory-sourced component, the is manufactured to the exact electrical specifications required by each covered machine, ensuring correct current flow and circuit protection from the moment it is installed. This Diode Assembly covers a broad range of configurations including standard, high-speed, and wheel-kit variants of the CRT36-24A, as well as standard and foldable ROPS builds of the RD12A-90.
Key Features
- Exact Electrical Specification: — Manufactured to OEM tolerances for correct forward-bias voltage and reverse-blocking performance, ensuring the diode handles the precise current loads of each covered machine without under- or over-rating.
- Drop-In Wiring Compatibility: — Matches the original connector configuration and polarity orientation, so the assembly seats directly into the existing harness without splicing or adapting leads.
- Broad Multi-Machine Fitment: — Verified for CRT36-24A ride-on trowel variants (including high-speed and wheel-kit builds), RD12A-90 tandem rollers (standard and foldable ROPS), and the BFS 2020AS floor saw.
- Protects Downstream Electrical Components: — A correctly functioning diode prevents reverse current from damaging charging circuits, control boards, and sensitive electronics; a failed diode can cause erratic operation or complete electrical system faults.
- Genuine OEM Sourcing: — Supplied directly through the Wacker Neuson parts network, carrying the same part number — 5000160721 — used by authorized service dealers worldwide.
A diode assembly is a one-way electrical valve that allows current to flow in only one direction within the machine's electrical circuit. In equipment like ride-on trowels, tandem rollers, and floor saws, the diode protects charging systems and control electronics by blocking voltage spikes and preventing reverse current from feeding back through sensitive components. When a diode assembly fails, symptoms can range from battery drain and charging faults to erratic control behavior or complete electrical shutdown, making timely replacement critical to keeping the machine operational.
