The Wacker Neuson Toothed Lock Washer is a genuine OEM component designed for a wide range of Wacker Neuson AR external vibrators, FUE and KTU frequency converters, and related power equipment. As a direct factory replacement, this part carries the same tooth profile, material spec, and dimensional tolerances as the original — ensuring it seats and locks exactly as intended during assembly. Verified fitment spans multiple AR, FUE, and KTU series machines, including the AR 75, AR 64, AR 34, AR 26, FUE 1, FUE 2, FUE 3, FUE 4, KTU 1, and KTU 2 families, as well as the LBM 1/230V Light Balloon and A1500 power units.
Key Features
- Genuine OEM Tooth Integrity — Toothed profile matches the original factory geometry, delivering the correct bite and retention force needed to prevent fastener loosening under vibration loads.
- Drop-In Hardware Replacement — Shares the same bore diameter, outer dimension, and tooth count as the original, so it installs directly onto the fastener stack without rework or modification.
- Broad Series Compatibility — Confirmed fit across AR external vibrator series (AR 26 through AR 75), FUE and KTU frequency converters (042, 120, and 250 variants), LBM 1 light balloon units, and A1500 power units.
- Vibration-Environment Durability — Toothed lock washers in vibration equipment are subject to constant cyclic stress; this OEM-spec part maintains clamping load where standard flat washers would allow gradual fastener back-out.
- Electrical Safety Compliance — Used across frequency converters and external vibrators operating at voltages from 115V to 500V; correct hardware retention at terminal and housing fastener points is essential for safe electrical enclosure integrity.
A toothed lock washer works by biting into both the bearing surface of a fastener head and the mating surface beneath it, creating mechanical resistance that prevents the nut or bolt from loosening due to vibration or thermal cycling. In concrete vibration and power conversion equipment — where continuous high-frequency operation is the norm — even minor fastener loosening can compromise electrical connections, structural housings, or drive assemblies. A worn or missing lock washer allows fasteners to back out gradually, which can lead to intermittent faults, increased wear on adjacent components, or unsafe operating conditions in live electrical assemblies.
