The Wacker Neuson Piston Pin is a genuine OEM component designed for the PTS4V and PTS4V(I) heavy-duty trash pump series. Sourced directly from Wacker Neuson, this pin meets the exact dimensional and material specifications of the original part installed at the factory. It is a direct fit for both the standard PTS4V and the PTS4V(I) pump variants, making it the straightforward choice when rebuilding or servicing the engine end of your pump. Keep your PTS4V running at full output with a part engineered specifically for this application.
Key Features
- Exact OEM Dimensions — Manufactured to the precise diameter and length tolerances required for correct wrist pin-to-connecting rod and pin-to-piston bore fit in the PTS4V engine assembly.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component under part number 5200001352, ensuring full material and hardness conformance with the original specification.
- Direct Fitment for PTS4V Series — Compatible with both the PTS4V and PTS4V(I) trash pump models, covering the standard and inlet-check variants of this 4-inch self-priming pump line.
- Engine Integrity Under Load — A correctly sized piston pin maintains proper piston alignment and load transfer to the crankshaft, supporting full compression and consistent pump output during demanding dewatering operations.
- Fuel System and Combustion Safety — A worn or out-of-spec piston pin can cause piston slap, accelerated bore wear, and loss of compression — replacing it promptly helps prevent progressive internal engine damage.
The piston pin — also called a wrist pin — connects the piston to the small end of the connecting rod inside the engine, allowing the rod to pivot as the piston moves up and down in the cylinder bore. It transfers the force of combustion from the piston directly to the crankshaft, making it one of the most mechanically stressed components in the engine. When a piston pin wears, becomes loose, or loses its hardness coating, it causes piston slap and knocking noises, accelerated wear on the cylinder bore, and ultimately a loss of compression and pump performance that will worsen until the engine is rebuilt.
