Wacker Neuson 5000202778 Cylinder With Piston 47Mm

The Wacker Neuson Cylinder With Piston 47Mm is a genuine OEM assembly designed for the BTS 930 L3 and BTS 935 L3 cut-off saws and power cutters. Sourced directly from Wacker Neuson, this assembly meets the original engineering specifications the machines were built around, delivering the compression characteristics and dimensional accuracy required for correct engine operation. The is the factory-authorized replacement for both BTS 930 L3 and BTS 935 L3 applications, making it a straightforward like-for-like swap when the original cylinder or piston shows wear, scoring, or damage.

Key Features

• OEM-Matched Bore Tolerance — Machined to the original 47mm bore specification, ensuring correct compression and a proper piston-to-wall fit without additional sizing or machining work.
• Complete Assembly — Cylinder and piston supplied together as a matched unit, eliminating guesswork when sourcing components and simplifying the rebuild process.
• Direct-Fit for BTS 930 L3 and BTS 935 L3 — Confirmed fitment across both the cut-off saw and power cutter variants of these model lines, covering multiple machine configurations.
• Restores Full Engine Output — A worn or scored cylinder causes loss of compression, rough running, and hard starting; replacing with this genuine assembly brings combustion performance back to original operating levels.
• Genuine Wacker Neuson Part — Supplied under the original Wacker Neuson part number 5000202778, so you can verify compatibility with confidence before ordering.

The cylinder and piston assembly forms the core of a two-stroke engine's combustion chamber. The cylinder provides the bore in which the piston travels, and together they create the sealed compression space needed to ignite the air-fuel mixture and drive the crankshaft. When this assembly wears — through normal use, overheating, or inadequate lubrication — compression drops, power output falls, and the engine becomes difficult or impossible to start. Replacing the cylinder and piston as a matched pair restores the critical tolerances that allow the engine to run cleanly and at full power.
