Maintenance & Care Suggestions (Field Engineer Practical Tips)

Routine Inspection Items

Check the sealing parts (O-rings, gaskets, oil seals) every 8 working hours for aging, damage and leakage; inspect transmission shafts, bearings and chain reducers every 50 working hours for abnormal noise, heating and loosening; check the fastening of bolts, pins and springs every 100 working hours to avoid falling off.

Scheduled Replacement Cycle

Vulnerable sealing parts, filter elements and plunger springs: replace every 850 working hours or immediately after damage; transmission shafts, bearings and shaft sleeves: full inspection every 2600 working hours, replace when wear groove depth exceeds 0.4mm; fasteners and connecting parts: replace every 3500 working hours to avoid fatigue fracture.

Installation Avoidance Tips

Before installing bearings and transmission shafts, clean the mating shaft surface and bearing hole to avoid iron filings and mud impurities causing abnormal wear; when installing sealing parts, do not use brute force to avoid cutting the sealing edge; tighten fasteners with a torque wrench, and the torque error shall not exceed ±5% of the standard value to prevent over-tightening fracture or under-tightening loosening.

Storage &; Transportation Notes

Store parts in a dry, ventilated and dust-free environment, and apply anti-rust oil to metal parts for long-term storage; avoid direct sunlight for rubber and sealing parts to prevent aging; during transportation, use shock-absorbing packaging to avoid collision deformation of precision parts such as transmission shafts and bearings.
