The Wacker Neuson Crankshaft Complete is a genuine OEM component designed for the BTS series gasoline cut-off saws, including the BTS 930, BTS 935, BTS 1030, and BTS 1035 — covering both standard and L3 variants. As a direct factory replacement, this crankshaft is manufactured to the same specifications as the original part, ensuring a correct installation without the guesswork of sourcing a cross-referenced substitute. Whether you're overhauling a high-cycle rental unit or restoring a saw that's seen hard use on a demolition site, part number brings the engine back to its original operating condition. Confirm your machine's model and serial number against the fitment list before ordering to ensure compatibility.
Key Features
- Genuine OEM Crankshaft Tolerancing — Manufactured to Wacker Neuson's original dimensional specs for correct bearing journal fit, stroke geometry, and rotational balance within the BTS engine assembly.
- Drop-In Engine Replacement — Engineered to mate directly with the existing connecting rod, bearings, and seals in the BTS series engine cases — no re-machining or custom fitting required.
- Broad BTS Series Coverage — Compatible with BTS 930, BTS 935, BTS 1030, and BTS 1035 models, including both standard and L3 configurations with 20mm and 1-inch arbor variants.
- Restores Full Power Output — A worn or damaged crankshaft causes vibration, power loss, and uneven blade speed; replacing it with 5000108123 returns the saw to smooth, consistent cutting performance.
- Fuel System and Ignition Timing Integrity — The crankshaft drives the engine's timing events; an out-of-spec or cracked crank can cause hard starting, misfiring, or uncontrolled engine behavior — making correct replacement essential for safe operation.
The crankshaft is the central rotating component of a two-stroke engine, converting the linear force of the piston's power stroke into the rotational energy that drives the blade. In a cut-off saw like the BTS series, the crankshaft operates under high-speed, high-load conditions — particularly during aggressive cuts through concrete, masonry, or steel. When a crankshaft develops wear on its journals, cracks in the web, or damage to the bearing surfaces, the result is increased vibration, loss of power, and ultimately engine seizure if left unaddressed. Replacing it with a genuine OEM unit like the 5000108123 restores proper engine dynamics and protects the surrounding components from secondary damage.
