The Wacker Neuson Alternator Screw is a genuine OEM Alternator Screw designed for the LTS7K, LTS8K, LTS4K, and LTE4K series light towers. Sourced directly from Wacker Neuson, this is an exact OEM replacement — manufactured to the same specifications as the original hardware installed on your machine. Fitment covers a wide range of LTS and LTE configurations, including 50 Hz and 60 Hz variants, Metal Halide and LED models, and both Trailer and Skid-mounted units.
Key Features
- OEM Thread and Torque Spec Integrity — Manufactured to the exact thread pitch, grade, and dimensions of the original fastener, ensuring proper clamping force on the alternator assembly without risk of stripping or under-torquing.
- Drop-In Hardware Replacement — Installs directly into the existing alternator mounting position with no reworking of threads or hardware, making it a straightforward swap during servicing.
- Broad LTS and LTE Series Coverage — Compatible with LTS7K (50 Hz and 60 Hz, Metal Halide), LTS8K, LTS4K (50 Hz and 60 Hz, LED), and LTE4K light towers in both Trailer and Skid configurations.
- Alternator Security Under Load — A correctly torqued alternator fastener keeps the alternator firmly seated during operation, preventing vibration-induced movement that can damage wiring, loosen connections, or cause premature alternator failure.
- Electrical System Safety — Loose or failed alternator mounting hardware can allow the alternator to shift under load, creating the risk of short circuits or arcing in the electrical system — using the correct OEM fastener helps maintain safe, stable electrical output.
The Alternator Screw is a critical fastener that secures the alternator to its mounting position within the light tower's power generation system. The alternator is responsible for converting mechanical engine output into electrical power to run the lights and any auxiliary loads — if the mounting hardware fails or loosens, the alternator can shift, placing stress on connected wiring and drive components. Replacing a worn or damaged Alternator Screw with a verified OEM part restores the secure, stable mounting the alternator needs to deliver consistent electrical output through every hour of operation.
