Detailed Inspection Procedures
Follow these step-by-step procedures for key inspection areas on your crawler excavator to ensure thoroughness and consistency.
Undercarriage Inspection
- Park excavator on level, firm ground with bucket grounded
- Clean undercarriage thoroughly before inspection
- Check track tension by measuring sag (refer to manual)
- Inspect each track shoe and connecting pin for damage
- Examine drive sprockets for tooth wear and damage
- Check idlers for smooth rotation and seal integrity
- Inspect all carrier rollers and track rollers for wear
- Look for oil leaks from roller seals and final drives
- Check track frame for cracks, bending, or damage
- Document any abnormal wear patterns for monitoring
Hydraulic System Inspection
- Park on level ground with all attachments lowered
- Check hydraulic oil level in sight glass when cold
- Inspect oil for discoloration, cloudiness, or debris
- Examine all visible hydraulic hoses for wear or leaks
- Inspect cylinder rods for scoring, pitting, or damage
- Check for leaks at all cylinder seals (boom, arm, bucket)
- Look for leaks at swing motor and travel motors
- Check hydraulic filter restriction indicators
- Inspect hydraulic tank breather for clogging
- Verify all hydraulic fittings are tight and not leaking
Attachment Inspection
- Lower bucket to ground and relieve hydraulic pressure
- Check bucket teeth, adapters, and cutting edge wear
- Inspect bucket for cracks, especially at stress points
- Check bucket side cutters and wear plates
- Inspect all pins and bushings at boom-arm-bucket joints
- Check quick coupler locking mechanism if equipped
- Look for cracks in boom structure, especially at pivot points
- Inspect arm (stick) for damage, bends, or cracks
- Check boom and arm cylinders for leaks and damage
- Verify all grease fittings are functioning and lubricated
Engine Compartment Inspection
- Ensure engine is off and cool before inspection
- Check engine oil level on dipstick (cold or warm per manual)
- Inspect coolant recovery bottle level (cold check)
- Examine radiator and oil cooler for debris and damage
- Check fan belt tension and condition
- Inspect all visible hoses for cracks, leaks, or swelling
- Verify air filter restriction indicator status
- Drain water separator if water is visible
- Check battery terminals for corrosion and tightness
- Inspect wiring harness for damage or loose connections
