The Wacker Neuson Piston Pin is a genuine OEM component designed for BFS and BFSX series floor saws and the CRT36-25 ride-on trowel. As a direct OEM part, is manufactured to the exact tolerances required to maintain proper piston-to-connecting-rod alignment inside the engine. This pin fits a broad range of BFS and BFSX models — including the BFS 1345B, BFS 1350B, and their BZ variants — giving contractors and service technicians a single verified part number for multiple machines in their fleet.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to the exact diameter and surface-hardness tolerances required for correct piston travel and minimal bore wear.
- Drop-In Engine Fitment — Engineered to seat directly into the piston bore and connecting rod without additional machining or sizing.
- Broad Model Coverage — Fits BFS18D, BFS20D, BFSX18, BFSX20, BFS 1345B, BFS 1350B, BFS 1345BZ, BFS 1350BZ floor saws, and the CRT36-25 ride-on trowel series.
- Sustained Engine Performance — A correctly fitted piston pin keeps the piston and rod operating on the designed axis; a worn or loose pin causes knocking, increased blowby, and accelerated cylinder wear that shortens engine life.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so part number 5000215863 matches the original specification without substitution or guesswork.
The piston pin — sometimes called a wrist pin — is the cylindrical link that connects the piston to the small end of the connecting rod inside the engine. It transfers the force of combustion from the piston down through the rod and into the crankshaft, converting that energy into rotational power. When a piston pin wears, becomes loose, or fails, the result is audible knocking under load, loss of compression, and rapid secondary damage to the piston, bore, and rod bearings — making prompt replacement critical to keeping an engine serviceable.
