Key Features

• Genuine OEM Specification — Manufactured to Wacker Neuson's original design tolerances, ensuring the key seats correctly and transfers torque without slippage or play.
• Cross-Family Compatibility — A single part number covering CT trowels, PT/PG/PDT/PDI pumps, GP/GPi/GPSi generators, VP/WP/BPU vibratory plates, BFS floor saws, and more — ideal for stocking one part that serves an entire mixed fleet.
• Drop-In Shaft Fit — Designed to seat directly into the existing keyway on compatible shafts, maintaining proper shaft-to-component alignment without machining or modification.
• Prevents Power-Transfer Failure — A worn or missing fitting key allows drive components to slip on the shaft, causing loss of output and accelerating wear on surrounding components; replacing it restores full torque transfer.
• Verified Wacker Neuson Part Number — Part number 5000156464 is the authoritative OEM reference, eliminating sourcing errors when ordering for multiple machine types.

A fitting key is a small but critical mechanical component that locks a rotating part — such as a pulley, gear, or impeller — to a shaft so that the two turn together as a single unit. It sits in a machined slot called a keyway, cut into both the shaft and the mating component, and prevents any rotational slipping between them. When a fitting key shears, deforms, or goes missing, the driven component can spin independently of the shaft, resulting in a complete loss of mechanical output — the machine runs but delivers no useful work. Because this part is shared across such a broad range of Wacker Neuson equipment families, keeping a 5000156464 on the shelf is a practical choice for any shop or fleet operation that services Wacker Neuson machines regularly.
