Komatsu WA70 Pins & Bushings

Komatsu WA70 Pins & Bushings

Komatsu WA70 compact wheel loaders are engineered for maneuverability and high productivity in landscaping, construction, snow removal, agriculture, and municipal operations. These machines operate under continuous articulation and repetitive bucket cycling, placing sustained stress on loader arm and linkage pivot systems.

WQParts supplies heavy-duty aftermarket pins and bushings for Komatsu WA70 compact wheel loaders engineered for dimensional accuracy, proper hardness, and durability in high-cycle load-and-carry environments.

Primary Wear Locations

  • Loader arm pivot connections
  • Z-bar and linkage assemblies
  • Bucket hinge and rollback joints
  • Quick coupler and attachment interfaces
  • Center articulation joints (where applicable)

Operational Wear Drivers

Compact wheel loaders often perform repetitive bucket cycles on abrasive materials such as sand, gravel, salt, and aggregate. Wear is accelerated by:

  • Constant bucket curling and dumping cycles
  • Side loading during grading and snow operations
  • Travel vibration combined with pivot articulation
  • Abrasive contamination entering joints
  • Inconsistent lubrication intervals

Why Precision Fit Is Critical

Excess pivot clearance reduces bucket control, increases stress at linkage components, and accelerates bore deformation. Maintaining proper pin and bushing tolerances protects structural loader arms and reduces long-term repair costs.

Material & Manufacturing Considerations

Pins must resist scoring and impact while maintaining core toughness. Bushings must hold inside and outside diameter tolerances to control clearance under load. WQParts focuses on aftermarket components selected for severe-duty compact loader applications.

Signs of Wear

  • Bucket play during reversal
  • Impact or clunking noise at pivot joints
  • Visible scoring on pins
  • Uneven bushing wear patterns
  • Accelerating clearance at articulation points

Why Buy from WQParts?
