The Wacker Neuson is a genuine OEM Toothed Lock Washer designed for the DRYVEX AD115LGR, AD85LGR, and AD75LGR dehumidifier series. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, the matches the exact tooth profile, inner diameter, and material specification of the original hardware used during factory assembly. This ensures the fastener joint it secures maintains the correct clamping force and vibration resistance throughout the unit's service life. If you're servicing any of the listed AD-series dehumidifiers, this is the correct replacement washer to restore the assembly to its original specification.
Key Features
- Genuine OEM Tooth Geometry — Hardened serrations match the original bite angle and depth, locking fasteners securely even under continuous vibration from dehumidifier operation.
- Direct Hardware Replacement — Matches the original inner diameter and outer profile for a drop-in installation with no reworking of mating hardware.
- Confirmed Fitment — AD-Series Dehumidifiers — Verified for the DRYVEX AD115LGR, DRYVEX AD85LGR, and AD75LGR dehumidifiers by Wacker Neuson part number 5000183302.
- Vibration-Resistant Locking Action — Toothed design bites into both the fastener face and the mating surface, preventing self-loosening in assemblies subject to motor or fan-induced vibration.
- Electrical Safety Compliance — On dehumidifier assemblies where this washer secures grounding or electrical panel hardware, using the correct OEM-spec toothed washer maintains the integrity of the ground path and supports electrical safety requirements.
A toothed lock washer is a hardened, serrated fastener component placed beneath a bolt head or nut to resist loosening caused by vibration or dynamic loads. The inward- or outward-facing teeth dig into the contact surfaces when the fastener is tightened, creating a mechanical lock that a standard flat washer cannot provide. In equipment like dehumidifiers — where motors, fans, and compressors generate continuous vibration — fasteners can gradually back out over time if the wrong washer type is used or if a worn washer is not replaced. A failed or missing toothed lock washer can lead to loose panels, misaligned components, or compromised ground connections, all of which affect the safe and reliable operation of the unit.
