The Wacker Neuson Piston Ring 47Mm is a genuine OEM component designed for the BTS 930 and BTS 935 series gasoline cut-off saws. Sourced directly from Wacker Neuson, this ring is manufactured to the exact dimensions and material specifications of the original part, ensuring a correct fit within the cylinder bore. Compatible across BTS 930 and BTS 935 variants including L3 editions, this is the dependable replacement to reach for when an engine inspection or top-end rebuild is on the schedule.
Key Features
- OEM-Grade Ring Geometry — Manufactured to the precise 47mm diameter and ring gap tolerances required by the BTS engine, ensuring correct sealing contact against the cylinder wall.
- Direct Drop-In Replacement — Designed to seat into the piston ring groove without modification, maintaining the correct end-gap and ring land fit for the BTS 930 and BTS 935 engine configuration.
- Broad BTS Series Coverage — Fits BTS 930 and BTS 935 models including standard and L3 variants, covering both the 20mm arbor and 1-inch arbor configurations.
- Restores Full Compression — A worn or broken piston ring causes loss of compression, hard starting, excessive oil consumption, and reduced cutting power. Replacing it with 5000126934 restores the engine seal and brings performance back to spec.
- Fuel System Integrity — Proper ring sealing prevents unburned fuel from bypassing into the crankcase, protecting the lower end and maintaining correct fuel-to-power efficiency in a high-RPM cut-off saw application.
The piston ring forms a dynamic gas seal between the piston and the cylinder wall in a two-stroke engine. Its primary job is to contain combustion pressure above the piston, transferring force efficiently to the crankshaft while preventing hot gases from blowing past into the crankcase. When a piston ring wears, cracks, or loses tension, compression drops, the engine becomes difficult to start, power output falls noticeably, and the saw may consume excessive fuel. Replacing the ring at the first sign of compression loss is the most cost-effective way to restore a BTS cut-off saw to full working condition.
