Operation Instructions
Replacing an excavator swing motor is complex and demands professional expertise. Prioritize safety by fully shutting down and stabilizing the machine, and wearing protective gloves and goggles. Verify the fault lies in the swing motor by inspecting related parts to avoid unnecessary replacement. Prepare required tools like wrenches, jacks, and ladders. Refer to the official manual or consult specialists for operational procedures. Disconnect power before removing the old motor step by step. Fit the new motor correctly, and fasten screws with proper torque—neither over-tightened nor loose—to prevent component damage.

Maintenance and Repair
I. Daily Inspection (Before Start-up) 1. Visual Leak Inspection: Check the motor housing, oil pipe joints, motor output shaft oil seal, and housing drain port for any oil seepage or leakage. If the oil seal leaks, hydraulic oil will enter the reducer, diluting the gear oil and damaging the gears. 2. Listen for Abnormal Noises: Rotate the machine left and right, listening for any metallic friction or clicking sounds; check for any jamming or vibration during rotation. 3. Slewing Brake Check: Park the machine on a slope and check if it rolls (drifts). Failure to brake is a major safety hazard; continue working immediately. 4. Hydraulic Oil Level and Temperature: Check the hydraulic oil dipstick when the machine is cold; the oil level should be within the standard range. During operation, the oil temperature should not exceed 80℃, as high temperatures will accelerate the aging of seals. 5. Slewing Bearing Large Gear Ring: Clean off any dirt, inspect the gear surface, and apply grease as needed (routinely apply slewing bearing grease every 250 hours). Check for any loose connecting bolts.
