The Wacker Neuson Piston is a genuine OEM Piston designed for the BFS 1345B, BFS 1350L, and BFS 1345BZ petrol floor saws. As a factory-sourced component, it is manufactured to the same tolerances and material standards as the original part fitted at the point of assembly. This makes the a straight-swap replacement that restores proper engine compression and combustion performance to your floor saw. Confirm your model number before ordering to ensure this piston is the correct fit for your machine.
Key Features
- OEM Compression Tolerancing — Manufactured to the precise bore dimensions and ring-groove specifications of the original, ensuring consistent cylinder seal and combustion efficiency.
- Direct-Swap Installation — Machined to the same pin bore, crown profile, and skirt geometry as the factory part, so it drops into the cylinder bore without modification to connecting rod or wrist pin hardware.
- Broad BFS Series Fitment — Compatible with the BFS 1345B (ø 450 mm/18 in), BFS 1350L, and BFS 1345BZ petrol floor saws, covering multiple configurations within the BFS range.
- Restored Cutting Power — A worn or scored piston causes loss of compression, hard starting, and reduced blade torque; replacing it with a correctly spec'd OEM piston brings engine output back to rated performance.
- Fuel System Integrity — Proper piston-to-wall clearance maintained by a genuine OEM part prevents blow-by, which can contaminate the crankcase oil and accelerate wear on other internal engine components.
The piston is the reciprocating component inside the engine cylinder that converts the force of combustion into the rotational movement that drives the saw blade. It works in conjunction with the piston rings to seal combustion gases above the piston and prevent oil from entering the combustion chamber from below. When a piston wears, becomes scored, or develops cracks, compression drops, the engine loses power, may smoke excessively, and can become difficult or impossible to start — making timely replacement critical to keeping a floor saw productive on the cut.
