This scraper ring removes crop residue and debris from the rotating shaft or seal surface within the hydraulic system. It is positioned on the shaft where it exits the housing, preventing contaminants from entering the fluid circuit and reaching downstream components such as the pump or control valves. Wear on the ring's inner contact face allows debris ingress, which can accelerate seal failure and cause external leakage. The ring is manufactured to match the original shaft diameter and housing groove dimensions, ensuring a proper interference fit without additional shimming. On reinstallation, inspect the shaft surface for scoring and replace the adjacent shaft seal if disturbed.
