Genuine OEM matters even on parts that seem generic. Bushings, pins, clips, washers — they were all specified for a load, an environment, and a mating part. Getting the exact one means the repair holds up.
This is the genuine Nilfisk Advance OEM SPROCKET AY 40B11, part number 56454079, brand new in the box.
