O‑ring is a common sealing element for bulldozer hydraulic and lubrication system. It fills assembly clearance to prevent leakage of hydraulic oil and gear oil, and blocks sand, mud and water from entering mating surfaces. Aging, swelling, crack and notch damage will lead to oil leakage and pressure relief, resulting in abnormal operation of transmission and hydraulic system.
