Commonly Worn Parts

Harvesters have several parts that are prone to wear and tear, including:

1. Blades/cutting parts: including main cutting blades, guards, cutting blade drive belts, etc.
2. Threshing drum and concave
3. Separating sieve and cleaning fan blades
4. Conveyor chains and sprockets
5. Rubber tracks or tires
6. Hydraulic components: including hydraulic cylinders, hoses, seals, etc.
7. Bearings
8. Filters: air filters, fuel filters, and oil filters, etc.

Signs to Replace Corresponding Parts

When the following signs appear, the corresponding parts need to be replaced:

1. Poor harvesting performance: If there is too much crop residue left after harvesting or the grains are not completely separated, it may indicate that the threshing drum and concave are severely worn and need to be checked and replaced in a timely manner.
2. Decreased power or overheating: If the engine power is insufficient or the operating temperature is too high, it may be due to a clogged air filter, resulting in poor air intake, or a cooling system failure. In this case, consider replacing the air filter element or checking and repairing the cooling system.
3. Reduced harvesting efficiency: If the cutting table runs slowly or the material conveying speed slows down, it may be due to aging and slackening of the transmission belt, chain elongation, or wear of the driving gear. At this time, check and replace the corresponding belt, chain, or gear.
4. Difficult to move or increased noise: If it is a rubber track harvester, if the track is loose or there are obvious cracks, it needs to be replaced; if it is a tire harvester, if the tire is excessively worn or punctured, it needs to be replaced. In addition, if there is abnormal noise during movement, it may be due to bearing wear or damage, and the relevant bearings need to be replaced.
5. Unstable hydraulic system operation: If the lifting and steering are slow or weak, it may be due to problems with hydraulic pumps, cylinders, valves, or seals. Check and replace the corresponding parts in a timely manner.
6. Large-scale oil leakage: Whether it is engine oil, hydraulic oil, or fuel leakage, it indicates that the sealing ring is damaged or other parts are damaged. Find the leakage point in time and replace the damaged sealing ring or parts.
