The Wacker Neuson Crankshaft is a genuine OEM crankshaft designed for PTS4V and PTS4V(I) series centrifugal trash pumps. As a direct factory replacement, this crankshaft matches the original component specification, ensuring a correct drop-in installation with no guesswork on fitment. Verified compatible with multiple PTS4V configurations, including the 100mm/4-inch centrifugal trash pump variants and the PTS4V(I) model. When your pump engine is down, sourcing the correct OEM part is the fastest path back to full operation.
Key Features
- Genuine OEM Precision Tolerancing — Manufactured to exact dimensional specs for the PTS4V engine, ensuring correct bearing journal dimensions and proper rotational balance within the crankcase.
- Direct-Fit Replacement — Designed to install in place of the original crankshaft with correct stroke geometry and journal sizing, matching the existing connecting rod and main bearing interfaces.
- Broad PTS4V Series Coverage — Fits PTS4V and PTS4V(I) 100mm/4-inch centrifugal trash pumps across multiple machine configurations.
- Restores Full Engine Output — A worn or damaged crankshaft causes excessive vibration, loss of power, and accelerated bearing wear; replacing it returns the pump engine to its rated performance.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this part carries the same part number used by authorized service dealers, giving you confidence in authenticity and long-term durability.
The crankshaft is the central rotating component of the pump engine, converting the up-and-down motion of the piston into the rotational force that ultimately drives the pump impeller. It must maintain precise rotational balance and consistent journal geometry to keep bearings, seals, and connecting rods functioning correctly. When a crankshaft is worn, cracked, or out of tolerance, the result is excessive vibration, oil leaks at the main seals, accelerated internal wear, and ultimately engine failure — making prompt replacement critical to keeping your trash pump operational.
