The Wacker Neuson Piston is a genuine OEM component designed for PT2H series pumps. Sourced directly from Wacker Neuson, this piston meets the exact specifications of the original part installed at the factory — no guesswork on fitment or function. It is confirmed compatible with the PT2H Pump and PT2H models, making it a straightforward, confidence-inspiring replacement for worn or damaged units. When you need the right part the first time, the OEM designation gives you that assurance.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original piston tolerances, ensuring correct bore fit, stroke travel, and compression sealing within the pump cylinder.
- Drop-In Replacement — Engineered to install in the same position and orientation as the original, with matching bore diameter and pin geometry for a direct swap during service.
- Confirmed PT2H Compatibility — Verified fitment for PT2H Pump and PT2H series, so you can order with confidence that 5100017215 is the correct part for your machine.
- Sustained Pump Output — A correctly fitted piston maintains proper displacement and pressure build-up, keeping the pump delivering consistent flow and lift performance across demanding applications.
- Fuel System Integrity — As a pressurized moving component in the pump assembly, using a correctly spec'd OEM piston helps maintain proper sealing and prevents premature wear on adjacent cylinder and valve components.
The piston is the core reciprocating component inside a pump's cylinder — it moves back and forth to draw fluid in on one stroke and force it out on the next, generating the pressure and flow the pump is built to deliver. A worn or damaged piston loses its ability to seal against the cylinder wall, which leads to reduced output, loss of prime, and increased stress on surrounding components. Replacing a failed piston with a correctly dimensioned OEM part restores full displacement and gets the pump performing as intended.
