The Wacker Neuson Lock Washer is a genuine OEM component designed for the Arctic Bear HD series indirect mobile air heaters, including both the natural gas and diesel-powered configurations. As a factory-sourced part, it is manufactured to the exact dimensions and material grade specified for these units, ensuring proper seating and holding force in the application it was built for. This lock washer is a direct OEM replacement for Arctic Bear HD models and. Keeping a supply of the correct fastener hardware on hand helps you get your heater back in service quickly without sourcing substitutes that may not match the original specification.
Key Features
- Genuine OEM Material Grade — sourced directly from Wacker Neuson, this lock washer meets the original hardness and tension retention spec required for the Arctic Bear HD heater assembly.
- Exact-Fit Hardware — matches the original inside diameter, outside diameter, and thickness, so it installs in the same position without any rework or adjustment.
- Broad Arctic Bear HD Compatibility — confirmed fitment across Arctic Bear HD indirect mobile air heaters in both natural gas (5000620199) and diesel (5000620197) variants.
- Secure Fastener Retention — a correctly functioning lock washer prevents fasteners from backing out under vibration and thermal cycling, both of which are common operating conditions in portable heater applications.
- Fuel System and Structural Integrity — loose or missing fastener hardware in an air heater can compromise sealed connections near the burner and fuel circuit; using the correct OEM lock washer helps maintain assembly integrity.
A lock washer is a small but critical piece of fastener hardware placed beneath a bolt or nut to resist loosening caused by vibration, thermal expansion, and contraction. In portable indirect air heaters like the Arctic Bear HD, components are subject to repeated heat cycles and transport vibration, both of which can cause standard fasteners to back out over time. When a lock washer wears flat, cracks, or is omitted entirely, fastener joints lose clamping force — potentially allowing panels, covers, or fuel-circuit connections to loosen in service.
