The Wacker Neuson is a genuine OEM Locking Disc designed for the BTS series gasoline cut-off saws, including the BTS 930, BTS 935, BTS 1030, BTS 1035, and BTS 1035 L3 models. Sourced directly from Wacker Neuson, this part is manufactured to the exact tolerances required for safe and correct blade retention on these machines. Whether you're running a 20mm or 1-inch arbor configuration, the is the correct OEM-specified disc for your saw. Confirm your model number before ordering to ensure a direct match.
Key Features
- OEM-Spec Retention Geometry — Manufactured to Wacker Neuson's exact dimensional tolerances, ensuring the locking disc seats and clamps the blade correctly without play or slippage.
- Direct Drop-In Replacement — Installs in the same position as the original, with no modification to the blade guard assembly or arbor hardware required.
- Broad BTS Series Coverage — Fits BTS 930, BTS 935, BTS 1030, BTS 1035, and BTS 1035 L3 cut-off saws across both 20mm and 1-inch arbor configurations.
- Blade Security Under Load — A correctly functioning locking disc keeps the cutting wheel firmly seated during high-RPM operation; a worn or damaged disc risks blade movement and loss of cutting control.
- Blade-Change Safety — As the component that locks the spindle during blade swaps, a genuine OEM locking disc is critical for safe, controlled wheel changes on the BTS platform.
- Genuine Wacker Neuson Part — Carries the authentic Wacker Neuson part number 5000108143, so you can order with confidence that you're receiving the same component installed at the factory.
The locking disc on a cut-off saw serves a dual purpose: it secures the cutting wheel to the arbor during operation and locks the spindle in place when the blade needs to be changed. During cutting, it bears the clamping load that keeps the wheel from shifting under the significant rotational forces generated at full throttle. When the disc wears, cracks, or is lost, the blade cannot be properly torqued to the spindle — creating a safety hazard and taking the saw out of service until the part is replaced.
