Black & Decker 90511237 Spare Part - BELT DRIVE

DeWalt 90511237 — Toothed rubber drive belt for belt sanders. This part is the replacement drive/timing belt (manufacturers’ reference 90511237, also listed as 98XL‑031 on some listings) used to transfer motor torque to the sanding drum; it’s a toothed, flexible rubber belt sized for small benchtop/belt sanders.

Common fit examples reported by parts suppliers: Black & Decker KA86 series belt sander and several BR318 variants (BR318, BR318‑AR, BR318‑B3LZ) — these model listings reference part 90511237 as the correct drive belt.

Quick notes for buying/repair: this is a direct drive/timing belt replacement (not a sanding abrasive) — check your sander’s model plate or the original belt for the 90511237 or 98XL‑031 marking to confirm fit before installing. When ordering DeWalt parts, matching the part number to your tool’s type designation ensures you get the correct replacement.
