• Lubricate Moving Parts: Apply recommended grease to bushings for smooth operation.

Installation Checks

After installation, confirm the following:

• Proper Thrust Rod Angle: Ensure the angle is within the manufacturer's specifications.
• Bushing Compression: Verify that bushings are properly compressed for secure retention.
• Adequate Clearance: Check for sufficient clearance between components to prevent friction.
• Secure Fasteners: Ensure all fasteners are tightened to the recommended torque values.

Maintenance Guidelines

Regular maintenance ensures long-term reliability:

• Monthly: Visual check for cracks or deformation.
• Quarterly: Assess bushing condition for wear or damage.
• Annually: Verify complete fastener torque and inspect for corrosion.
• As Needed: Apply corrosion treatment to protect against environmental factors.

Replacement Indicators
