3. Installation Instructions

Please follow these steps carefully for proper installation. Professional installation is recommended.

1. Preparation: Ensure the engine is off and cool. Disconnect the battery to prevent accidental starting or electrical issues. Identify the existing throttle linkage and its connection points on the P-Pump.
2. Removal of Old Linkage: Carefully remove the old throttle linkage rod. Note the orientation and connection method of the existing ball studs and rod.
3. Component Identification: Familiarize yourself with the new MOTOQUEEN throttle linkage assembly. It includes the main rod and two ball studs. Note that one ball stud may connect clockwise and the other counter-clockwise.
4. Initial Connection: Connect the longer threaded end of the new throttle rod to its corresponding interface on the P-Pump. Ensure it is securely fastened but do not overtighten.
5. Ball Stud Attachment: Attach the two ball studs to their respective connection points. Pay close attention to the threading direction: one ball stud typically turns clockwise to connect, while the other turns counter-clockwise. This is crucial for proper assembly.
6. Adjustment: Once both ends are connected, check for proper throttle movement. The rod may require minor cutting or modification to function correctly for your specific application. Adjust the length of the rod using the threaded section to achieve the correct throttle tension and full range of motion without binding.
7. Final Check: Verify all connections are secure. Manually operate the throttle to ensure smooth movement from idle to full throttle. Reconnect the battery.

4. Operating Instructions

Once installed and properly adjusted, the throttle linkage assembly operates in conjunction with your vehicle's accelerator pedal to control engine speed. Ensure smooth and unrestricted movement of the pedal. Any stiffness or binding should be addressed immediately.

5. Maintenance

To ensure the longevity and optimal performance of your MOTOQUEEN Throttle Linkage Assembly Rod, consider the following maintenance tips:

• Regular Inspection: Periodically inspect the rod and ball studs for any signs of wear, corrosion, or damage. Check for looseness in the connections.
• Cleaning: Keep the linkage free from dirt, grime, and debris. A clean cloth can be used to wipe down the rod.
• Lubrication: Apply a small amount of appropriate grease or lubricant to the ball joint connections to ensure smooth operation and prevent premature wear.
• Corrosion Protection: While the rod is zinc-plated for corrosion resistance, extreme conditions may still cause issues. If any signs of rust appear, address them promptly.

6. Troubleshooting

If you encounter issues with your throttle linkage, consider the following:

• Stiff or Binding Throttle: Check for proper alignment and ensure no components are rubbing or catching. Re-adjust the rod length if necessary. Lubricate ball joints.
• Loose Connections: Ensure all nuts and ball studs are tightened to the manufacturer's specifications. Do not overtighten.
• Incorrect Threading: As noted in installation, one ball stud may have a clockwise thread and the other a counter-clockwise thread. Ensure they are installed correctly. If a component does not fit, verify the thread direction before forcing it.
• Modification Required: Some applications may require minor cutting or modification of the rod for optimal fit and function. If you are unsure, consult a professional mechanic.
