The Wacker Neuson Piston Pin is a genuine OEM component designed for PDT2A, PDT3A, and PDI3A series internal vibrators. As a direct OEM part, it is manufactured to the same specifications as the original, ensuring a correct, like-for-like replacement every time. This pin is confirmed to fit the PDT2A, PDT3A, and PDI3A models, so you can order with confidence knowing it will work with your machine. Keep a spare on hand to stay ahead of wear and avoid unnecessary downtime on the job.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact original tolerances, ensuring proper piston-to-connecting rod alignment and smooth reciprocating motion within the vibrator head.
- Drop-In Replacement — Engineered to the same profile as the factory-installed pin, fitting directly into the existing bore without modification to surrounding components.
- Confirmed Fitment — Verified for PDT2A, PDT3A, and PDI3A internal vibrators, covering the most common models in the Wacker Neuson PDT and PDI series lineup.
- Sustained Vibration Output — A correctly fitted piston pin maintains the precise oscillation frequency needed to consolidate concrete effectively; a worn or loose pin causes irregular vibration and can lead to accelerated internal wear.
- Sourced Direct from Wacker Neuson — Part number 5100056870 is an authorized OEM part, giving you traceability and confidence that you are installing the correct component for your machine.
The piston pin connects the piston to the connecting rod inside the vibrator head, transferring the reciprocating motion that generates the high-frequency vibration used to consolidate concrete. It must maintain a precise fit within its bore — too much clearance causes knocking, loss of vibration intensity, and rapid wear to surrounding components. When a piston pin wears or fails, the vibrator will deliver inconsistent or reduced output, compromising concrete consolidation and potentially damaging the internal mechanism further if left unaddressed.
