The Wacker Neuson Lock Nut is a genuine OEM component designed for E5000 Ground Heaters and CH5000 Cross Heaters. Sourced directly from Wacker Neuson, this lock nut meets the exact specifications required for these ground and cross heater units — covering diesel-fired, gas-fired, and generator-equipped configurations. Whether you're servicing an E5000 Ground Heater with a diesel or gas burner, or a CH5000 Cross Heater with an oil burner or integrated generator, part number is the correct OEM-specified fastener for the job.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's thread specification and torque rating, ensuring the lock nut holds secure under the thermal cycling and vibration stresses typical of ground and cross heater operation.
- Drop-In Replacement — Matches the original thread pitch, diameter, and locking mechanism of the factory-installed fastener, so installation requires no modification to existing hardware.
- Broad Heater Family Coverage — Fits the E5000 Ground Heater (diesel and gas burner variants) and CH5000 Cross Heater (oil burner and generator/oil burner configurations).
- Maintains Secure Assembly — A properly functioning lock nut prevents loosening caused by heat-induced expansion and contraction cycles; a worn or missing lock nut can lead to component misalignment or fastener failure during operation.
- Verified OEM Part Number — Part number 5000177813 is the Wacker Neuson-assigned reference for this application, making cross-referencing against your service manual straightforward.
A lock nut is a self-locking threaded fastener designed to resist loosening under vibration, thermal expansion, and mechanical stress. Unlike a standard nut, the locking feature — whether a nylon insert, distorted thread, or prevailing-torque design — creates additional friction that keeps the nut in position once torqued. In ground and cross heater applications, fasteners are exposed to repeated heating and cooling cycles that cause metal components to expand and contract; a lock nut maintains clamping force through these cycles. When a lock nut fails or is missing, connected components can work loose, potentially affecting burner alignment, panel integrity, or other critical assemblies within the heater unit.
