Wacker Neuson 5000202782 Piston 47mm

The Wacker Neuson Piston 47mm is a genuine OEM component designed for BTS 930 and BTS 935 series power cutters and cut-off saws. Sourced directly from Wacker Neuson, this piston delivers the exact dimensional tolerances and material specification required to maintain proper compression and engine performance in these machines. Compatible across the BTS 930 L3, BTS 935 L3, BTS 930, and BTS 935 model variants, the is the correct choice when rebuilding or overhauling the engine on these units. Ordering the genuine OEM part ensures the fit and function match what came out of the machine.

Key Features

• OEM Compression Integrity — Manufactured to the exact 47mm bore diameter specification, maintaining correct compression ratio for peak engine output in Wacker Neuson power cutters.
• Drop-In Engine Replacement — Designed to install directly into the existing cylinder bore with no machining or sizing adjustments needed on compatible BTS series engines.
• Broad BTS Series Coverage — Fits BTS 930, BTS 930 L3, BTS 935, and BTS 935 L3 power cutters and cut-off saws, covering both the 20mm arbor and 1-inch arbor variants.
• Restores Full Cutting Power — A worn or damaged piston causes loss of compression, hard starting, and reduced blade speed; replacing it with this genuine part brings engine output back to spec.
• Genuine Wacker Neuson OEM Part — Carries the Wacker Neuson part number 5000202782, confirming authenticity and traceability through the manufacturer's supply chain.

The piston is the reciprocating component inside the engine cylinder that compresses the air-fuel mixture and transfers combustion force to the crankshaft via the connecting rod. In a two-stroke cut-off saw engine, the piston also plays a direct role in port timing, which controls how the fuel mixture enters and exhaust exits the cylinder. When a piston wears beyond its service limit or suffers damage from heat or debris, the result is low compression, excessive oil consumption, rough running, and ultimately a loss of cutting performance that makes the machine unreliable on the job.
