The Wacker Neuson Lock Washer is a genuine OEM component designed for a wide range of Wacker Neuson indirect air heaters, hydronic surface heaters, heat exchangers, and ground heating systems — including the HI 770 XHD, CUB700, CUB400, HSH350, Pureheat, E5000, HX15, HX100, CH5000, and MC5200 series. As a genuine OEM part, the is manufactured to the exact specifications of the original hardware used on the production line, ensuring a correct and consistent fit. This lock washer is a small but critical fastener component that helps maintain secure, vibration-resistant connections throughout the heater assembly. Keep a supply on hand for routine service intervals or as part of a broader repair.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to exact dimensional and material specifications, ensuring correct clamping load and bite characteristics for threaded fasteners in heating equipment assemblies.
- Drop-In Hardware Replacement — Matches the original lock washer profile and inner diameter, so it seats correctly against mating surfaces without rework or shimming.
- Broad Heater Family Coverage — Compatible with the HI 770 XHD, CUB700, CUB400, HSH350, Pureheat, E5000, HX15, HX100, CH5000, and MC5200 series, covering indirect air, hydronic, and ground heating platforms.
- Vibration and Loosening Resistance — Lock washers in heater assemblies are exposed to continuous thermal cycling and mechanical vibration; the correct washer profile maintains fastener preload and prevents unwanted loosening over time.
- Fuel and Heat System Safety Relevance — In fuel system and burner assembly connections, properly tensioned fasteners secured with the correct lock washer help prevent dangerous fuel or combustion gas leaks — using the right OEM specification part matters here.
A lock washer is a hardened fastener component installed beneath a bolt or nut to resist loosening caused by vibration, thermal expansion, and contraction cycles. In indirect air heaters, hydronic heaters, and ground heating systems, fastener connections are subjected to repeated heat-up and cool-down cycles as well as mechanical vibration from burner operation and blower motors — conditions that can gradually back out inadequately secured fasteners. When a lock washer wears out, deforms, or is missing, fasteners can lose clamping force over time, potentially causing panels, brackets, or fuel and fluid line fittings to loosen. Replacing worn or damaged lock washers with the correct OEM specification part like the Wacker Neuson 5000167816 helps maintain the structural and operational integrity of the heater assembly.
