The Wacker Neuson 5000165578 Key is a genuine OEM component designed for the PT6LT and PT6LS trash pump series and the LTN6L, LTN6LE, LTN6L-V, LTN6L-V S, LTV6L, and LTC4L light tower series. Sourced directly from Wacker Neuson, this key meets the exact specifications of the original part it replaces. Its broad fitment coverage spans multiple configurations across both the pump and light tower product families, making it an essential stocking item for fleet operators and service technicians. Always confirm your model and machine number before ordering to ensure correct application.
Key Features
- Genuine OEM Specification Manufactured to the original dimensional and material tolerances required for a secure, rattle-free fit in the keyway, maintaining correct shaft-to-component engagement.
- Direct-Fit Replacement Drops into the existing keyway without machining or filing — the profile matches the OEM slot geometry on covered models.
- Wide Fitment Coverage Compatible with PT6LT and PT6LS trash pumps as well as LTN6L, LTN6LE, LTN6L-V, LTN6L-V S, LTV6L, and LTC4L light tower variants across 60 Hz and 50 Hz configurations.
- Torque Transfer Integrity A correctly fitted key locks rotating components to the shaft, preventing slippage that would otherwise cause premature wear to both the shaft and the mating hub.
- Verified Part Number Order by Wacker Neuson part number 5000165578 to ensure you receive the correct key profile for your equipment — cross-reference your model number before purchasing.
A key is a small precision-machined component that sits in a slot — called a keyway — cut into both a shaft and a mating part such as an impeller hub or pulley. Its function is to lock the two pieces together rotationally, so that torque is transmitted from the shaft to the component without slipping. When a key shears, deforms, or goes missing, the driven component spins freely on the shaft, causing an immediate loss of function — a pump impeller that no longer moves water, or a driven assembly that fails to rotate under load. Replacing a worn or damaged key promptly restores full power transmission and prevents secondary damage to the shaft and hub surfaces.
