Wacker Neuson 5000038248 Shaft Seal 17 X 30 X 7, 4B

The Wacker Neuson Shaft Seal 17 X 30 X 7, 4B is a genuine OEM seal designed for the BTS 13 and BTS 11 gasoline cut-off saws. As a direct-from-manufacturer component, is produced to the exact dimensional and material tolerances specified for these machines, ensuring correct seating and compression against the shaft. This seal is confirmed for the BTS 13 cut-off saw with 1-inch arbor and the BTS 11 cut-off saw with 7/8-inch arbor, making it a targeted replacement for operators running either configuration.

Key Features

• Genuine OEM Sealing Material — manufactured to the precise lip profile, durometer, and dimensional spec required for this shaft diameter, ensuring consistent compression and oil retention at the shaft interface.
• Direct Drop-In Replacement — sized at 17 x 30 x 7 mm with a 4B lip configuration, this seal seats directly into the existing bore without modification, restoring the factory-engineered fit at the shaft.
• Confirmed Fitment for BTS Cut-Off Saws — verified for the BTS 13 (1-inch arbor) and BTS 11 (7/8-inch arbor), covering both common arbor configurations in the BTS gasoline cut-off saw line.
• Prevents Lubricant Loss and Contamination Ingress — a correctly functioning shaft seal keeps lubricant in and dirt, dust, and debris out; a worn or failed seal accelerates internal wear and can lead to bearing failure.
• Fuel and Debris Environment Rating — cut-off saws operate in high-particulate, high-vibration conditions; this seal is engineered to maintain its integrity in the demanding environment of concrete and masonry cutting.

A shaft seal forms the dynamic barrier between a rotating shaft and the stationary housing around it. Its job is to retain the lubricant that keeps internal bearings and moving components running smoothly, while blocking dust, slurry, and debris from working their way inside — a particularly critical function on a cut-off saw used in concrete or masonry cutting. When a shaft seal wears out or fails, lubricant migrates out of the housing and contaminants migrate in, leading to accelerated bearing wear, increased heat, and eventual mechanical failure. Replacing a degraded seal promptly with the correct OEM part, such as Wacker Neuson 5000038248, is one of the most cost-effective ways to protect the drivetrain and extend the service life of the saw.
