The Wacker Neuson Shaft Seal 17 X 28 X 6, 5B is a genuine OEM seal designed for the BTS 13 and BTS 11 gasoline cut-off saw series. Sourced directly from Wacker Neuson, this part matches the exact material grade, dimensional profile, and compression specification of the original factory-installed seal. It is confirmed to fit 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 direct replacement for either variant. Verify your model number before ordering to ensure a correct match.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original compound specification, ensuring correct compression and long-term resistance to heat and fuel contamination common in cut-off saw applications.
- Exact Dimensional Fit — Dimensioned at 17 x 28 x 6 mm with a 5B profile, this seal seats correctly against the shaft bore without shimming or trimming.
- Confirmed Fitment for BTS Series — Compatible with the BTS 13 (1-inch arbor) and BTS 11 (7/8-inch arbor) gasoline cut-off saws from Wacker Neuson.
- Prevents Oil and Contaminant Ingress — A properly seated shaft seal keeps lubricant in and abrasive dust and debris out, protecting the crankshaft and internal bearings from accelerated wear.
- Fuel System Integrity — On cut-off saws, a degraded or leaking shaft seal can affect crankcase pressure, causing hard starting, rough running, and potential engine damage — replacing it promptly restores correct engine operation.
A shaft seal creates a dynamic barrier between a rotating shaft and its surrounding housing, preventing internal lubricants from escaping while blocking outside contaminants from entering the engine. In a gasoline cut-off saw like the BTS 13 or BTS 11, the shaft seal plays a direct role in maintaining the crankcase pressure required for proper two-stroke or four-stroke engine function. When this seal wears, cracks, or loses its compression rating, oil leaks, pressure loss, and ingestion of dust or debris can quickly lead to premature engine failure — making timely replacement essential for maintaining cutting performance and engine longevity.
