The Wacker Neuson 0108125 is a genuine OEM Shaft Seal designed for the BTS series gasoline cut-off saws, covering the BTS 930, BTS 930 L3, BTS 935, BTS 935 L3, BTS 1030, BTS 1030 L3, BTS 1035, BTS 1035 L3, and BTS 1140 L3 models. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, the 0108125 is manufactured to the same specifications as the original component installed at the factory. This seal is a precise drop-in fit for both standard arbor and L3-series configurations across the BTS family, making it the straightforward choice when servicing your cut-off saw. Confirming your machine's model number against the fitment list above ensures you receive the correct seal for your application.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material specification, delivering the compression and chemical resistance required for a high-RPM cut-off saw environment.
- Direct Spindle-Housing Fit — Engineered to seat correctly in the shaft bore without modification, restoring the original sealing interface between the rotating shaft and housing.
- Broad BTS Series Coverage — Fits BTS 930, BTS 935, BTS 1030, BTS 1035, and BTS 1140 models, including standard arbor variants and the L3 series power cutters.
- Prevents Lubricant Loss and Contamination Ingress — A fully functioning shaft seal keeps gear case lubricant contained and blocks dust, slurry, and debris from entering the spindle housing — a critical concern on any cut-off saw used in masonry or concrete cutting.
- Genuine OEM Part — Supplied under Wacker Neuson part number 0108125, ensuring part number accuracy and eliminating guesswork when cross-referencing against service documentation.
The shaft seal on a cut-off saw sits at the point where the blade spindle or drive shaft exits the gear housing, forming a barrier that keeps lubricating grease or oil inside the housing while blocking abrasive dust, water, and concrete slurry from working their way in. When this seal wears, cracks, or is displaced, the gear case loses lubrication rapidly and external contaminants accelerate wear on the internal gears and bearings. Replacing a failed shaft seal promptly with the correct OEM part — Wacker Neuson 0108125 — protects the surrounding drivetrain components and restores proper operation of the BTS cut-off saw.
