This Teflon reel bushing acts as a low-friction bearing surface in the header’s reel mechanism. It sits between the reel arm and its mounting shaft, allowing the reel to rotate freely during crop engagement. The bushing’s self-lubricating material reduces sliding resistance, which helps maintain consistent reel speed and crop flow into the auger. A worn bushing introduces play in the reel arm, causing uneven reel positioning and reduced feeding efficiency. The original part matches the housing bore tolerance, so no shimming or reaming is required during replacement.
