| Maintenance Level | Maintenance Interval | Maintenance Items | Operation Points | Remarks |
|---|---|---|---|---|
| Daily Maintenance | Before/after each operation (daily) | 1. Surface cleaning2. External damage inspection3. Oil seal leakage inspection4. Bolt looseness inspection | 1. Clean soil and gravel with a brush/low-pressure water gun; do not directly spray the oil seal2. Inspect the roller surface for cracks, deformation, and wear; mark if wear exceeds 1/3 of the original thickness3. No oil stains or drops at the oil seal is normal4. Visually check that bolts are not loose and have no obvious displacement | Immediately stop the machine for inspection if abnormalities such as oil leakage or cracks are found |
| Regular Maintenance | Every 500 operating hours | 1. Disassembly and in-depth cleaning2. Bearing rotation flexibility test3. Oil seal integrity inspection4. Lubrication of greaseable track rollers5. Torque retightening of fixing bolts | 1. Remove the track, take out the track roller, and clean internal oil stains and impurities2. Qualified if the bearing rotates smoothly without jamming, abnormal noise, or looseness when turned by hand3. Reuse the oil seal if its lip is not aged or cracked; otherwise, replace it4. Inject lithium-based grease until old oil is discharged5. Tighten bolts to a torque of 180-220 N·m | Skip the lubrication step for pre-lubricated track rollers and directly inspect the oil seal |
| Mid-term Maintenance | Every 1500 operating hours | 1. Roller body thickness measurement2. Inspection of matching degree between track and track roller3. Inspection of flatness of frame mounting surface | 1. Measure the roller surface thickness with a caliper and compare it with the original factory parameters2. Test run to check if the track deviates or shakes3. Clean rust and welding slag on the mounting surface to ensure tight fit | It is recommended to replace the track roller if the thickness deviation exceeds 10% |
| Long-term Maintenance | Every 3000 operating hours/complete machine overhaul | 1. Performance evaluation of track roller assembly2. Replacement of aged oil seals/bearings3. Batch inspection of track roller wear consistency |
