Detailed Inspection Procedures
Follow these step-by-step procedures for key inspection areas on your wheel loader to ensure thoroughness and consistency.
Hydraulic System Inspection
- Park loader on level ground with implements lowered
- Ensure hydraulic oil is at normal operating temperature
- Check hydraulic oil level in sight glass or dipstick
- Inspect oil color and clarity for contamination
- Check hoses for abrasion, bulges, and leaks
- Inspect cylinder rods for scoring, pitting, or damage
- Look for leaks at all fittings and connections
- Check hydraulic filter restriction indicators
- Inspect hydraulic coolers for debris and damage
- Document any findings in maintenance log
Articulation Joint Inspection
- Park on level ground, shut off engine, and apply parking brake
- Place articulation lock bar in position if equipped
- Clean articulation area thoroughly before inspection
- Check for proper lubrication at all grease points
- Inspect center hinge pin for excessive play or movement
- Check steering cylinders for leaks and secure mounting
- Look for cracks in frame near articulation point
- Inspect oscillation joint if equipped
- Check condition of articulation stops
- Remove lock bar and verify proper joint movement
Tire Inspection Process
- Conduct inspection when tires are cool
- Visually check inflation of all tires
- Inspect for cuts, bulges, and punctures on tread and sidewalls
- Check tread depth at multiple points around tire
- Look for embedded objects in tread (rocks, metal)
- Inspect tire wear pattern for alignment/loading issues
- Check valve stems for damage and ensure caps are present
- Inspect rims for cracks, dents, or deformation
- Verify all wheel nuts are present and tight
- Document and report any significant findings
Bucket & Attachment Inspection
- Lower bucket or attachment to ground
- Shut off engine and relieve hydraulic pressure
- Check bucket/attachment for cracks, especially at high-stress points
- Inspect cutting edge or teeth for wear and security
- Check side cutters and wear plates for condition
- Inspect pin connections for wear and proper retention
- If quick coupler equipped, verify locking mechanism function
- Check hydraulic couplings for leaks and damage
- Inspect lift arm linkage for wear and lubrication
- Document and report any issues requiring maintenance
