Written by Daisy. Oil seal maintenance is an important part of keeping combine harvesters productive during harvest time. These seals are designed to hold lubricant inside rotating assemblies while blocking dust, moisture, straw, and other contaminants from entering. However, peak season conditions can expose seals to extreme wear, high temperatures, shaft vibration, pressure variation, and frequent washing or cleaning. A strong maintenance plan should include pre-harvest inspection, correct spare seal preparation, scheduled checks during operation, and immediate response when leakage appears. Inspect the sealing area for cracks, wet dust, hardened rubber, abnormal noise, and overheating. Also check breathers, lubricant condition, shaft sleeves, and bearing play because these factors can shorten seal life. When replacing a seal, use the correct size and material, protect the sealing lip, avoid hammering directly, and keep the installation square. A high-quality agricultural machinery oil seal can reduce lubricant loss, protect bearings and gears, and help the machine complete harvest tasks without unexpected stops.
