The Wacker Neuson Set, Key is a genuine OEM component designed for the PTS4V series pumps. As a direct OEM replacement, this set delivers the exact fit and material specification required to maintain proper shaft-to-component engagement on your machine. Sourced directly from Wacker Neuson, part is confirmed to fit multiple PTS4V configurations, making it a straightforward service solution for this pump series.
Key Features
- Genuine OEM Key Material Integrity — Manufactured to Wacker Neuson's original hardness and dimensional spec, ensuring the key shears or holds exactly as engineered — critical for protecting drivetrain components.
- Drop-In Shaft Slot Fit — Sized to seat correctly in the keyway without filing or shimming, allowing a clean installation on PTS4V pump assemblies.
- PTS4V Series Compatibility — Verified fitment across multiple PTS4V pump variants, covering a range of serial configurations within this model family.
- Drivetrain Engagement Protection — A correctly fitted key set maintains positive drive between the shaft and mating component; a worn or missing key leads to slippage, loss of pump output, and accelerated wear on surrounding parts.
- Complete Set Supplied — Includes all keys in the set, so you have what you need on hand for a full service without sourcing individual pieces separately.
A key set provides the mechanical connection between a rotating shaft and its mating hub or impeller, transferring torque without allowing the two components to slip relative to each other. On a pump like the PTS4V, this connection is essential for delivering consistent water movement — if the key wears, shears, or goes missing, drive is lost and the pump stops performing. Replacing the key set with a correctly sized OEM part restores that positive drive connection and prevents secondary damage to the shaft or hub bore.
