The Wacker Neuson is a genuine OEM Lock Washer designed for a broad range of Wacker Neuson equipment, including CT36BDT and CT48BDT walk-behind concrete trowels, PT2B and PT3B centrifugal trash pumps, the PD3B diaphragm pump, and B 3000 and B 5000 gasoline power units for internal vibrators. As a direct OEM part, the is manufactured to the same specification as the original hardware installed at the factory. Whether you're servicing a concrete finishing machine or a water management pump, this lock washer delivers the secure fastening performance your equipment depends on.
Key Features
- Genuine OEM Locking Integrity — Manufactured to exact Wacker Neuson tolerances, ensuring consistent bite and resistance to loosening under vibration loads typical of trowels, pumps, and power units.
- Drop-In Hardware Replacement — Matches the original fastener stack-up precisely, so it seats and torques correctly without shimming or adaptation.
- Wide Cross-Equipment Compatibility — A single part number covers CT-series walk-behind trowels, PT/PD-series pumps, and B-series gasoline power units, making it a practical stocking item for mixed Wacker Neuson fleets.
- Vibration-Resistant by Design — Lock washers are the last line of defense against fastener backout; using the correct OEM spec part maintains clamping force even in high-cycle, high-vibration operating environments.
- Fastener System Safety — In pumps and rotating power equipment, a failed or incorrect lock washer can allow critical fasteners to back out, creating fluid leaks or mechanical failures; replacing with the correct OEM part restores the intended safety margin.
A lock washer is a small but essential hardware component placed beneath a nut or bolt head to prevent unintentional loosening caused by vibration, thermal cycling, or dynamic loads. It works by biting into both the fastener and the mating surface, creating friction that resists rotational backout. In equipment like concrete trowels and trash pumps — which generate continuous vibration during operation — a worn, damaged, or incorrect lock washer can allow fasteners to gradually loosen, leading to misalignment, leaks, or component separation. Replacing a failed lock washer promptly with the correct OEM part restores the integrity of the fastener joint and keeps the surrounding assembly secure.
