• Remove old shear stop by following OEM service manual steps.
• Install new 16H030 component with recommended torque specs.
• Verify alignment and secure fasteners to prevent leaks.

Maintenance Tips

Regular inspection of the shear stop and adjacent fluid passages helps detect wear or deformation. Clean with appropriate solvent and avoid abrasive tools. Replace at the first sign of metal fatigue to prevent spray quality issues.

Safety Information

• Always relieve system pressure before servicing.
• Wear eye and hand protection during installation.
• Avoid exposure to solvent vapors during cleaning.
