2. Setup

Proper installation of the valve refacer wheel is crucial for safe and effective operation. Always ensure the refacer machine is powered off and disconnected from its power source before beginning installation.

Safety First: Wear appropriate personal protective equipment, including safety glasses and gloves, during installation and operation.
Inspect the Wheel: Before installation, carefully inspect the GOODSON Valve Refacer Wheel for any signs of damage, cracks, or imperfections. Do not use a damaged wheel.
Clean Mounting Surfaces: Ensure that the mounting flange and spindle of your Sioux Valve Refacer (models 680, 956, 2001, or 2075) are clean and free of debris or burrs.
Mount the Wheel: Carefully place the 7-inch refacer wheel onto the spindle, ensuring it sits flush against the mounting flange.
Secure the Wheel: Install the retaining nut or clamp according to your specific Sioux refacer's instructions. Tighten securely, but do not overtighten, as this can damage the wheel.
Test Run: After installation, reconnect power and perform a brief test run at a low speed to ensure the wheel is properly seated and runs true without excessive vibration.

3. Operating Instructions

This section outlines general procedures for operating the GOODSON Valve Refacer Wheel. Always refer to your specific Sioux Valve Refacer machine's manual for detailed operational steps and safety precautions.

Valve Preparation: Ensure the valve to be refaced is clean and free of carbon buildup or debris.
Machine Settings: Adjust your Sioux refacer's settings (e.g., feed rate, depth of cut, angle) according to the valve specifications and desired finish. The GOODSON wheel is designed for a straight / 15-degree profile.
Coolant Application: Use appropriate coolant as recommended by your refacer machine's manufacturer to prevent overheating and extend wheel life.
Refacing Process: Engage the valve with the rotating wheel carefully. Apply steady, even pressure and maintain a consistent feed rate. Avoid aggressive cutting, which can lead to poor finish or wheel damage.
Inspection: Regularly inspect the valve face during the refacing process to achieve the desired angle and surface finish.
Dressing the Wheel: Periodically dress the refacer wheel to maintain its cutting efficiency and ensure a clean, sharp abrasive surface. Follow your refacer machine's instructions for wheel dressing.

4. Maintenance

Regular maintenance of your GOODSON Valve Refacer Wheel will ensure its longevity and consistent performance.

Cleaning: After each use, clean the wheel to remove any accumulated swarf or debris. Use a brush or compressed air, ensuring the machine is off and disconnected.
Inspection: Periodically inspect the wheel for wear, cracks, or chipping. Replace the wheel if any significant damage is observed.
Storage: Store the wheel in a dry, protected environment, away from extreme temperatures and humidity, to prevent degradation of the abrasive material.
Dressing: As mentioned in operation, regular dressing is a key maintenance step to expose fresh abrasive and maintain cutting performance.

5. Troubleshooting

This section addresses common issues that may arise during the use of the valve refacer wheel.

Problem	Possible Cause	Solution
Poor surface finish on valve	Worn or glazed wheel Incorrect feed rate or depth of cut Insufficient coolant Vibration in machine	Dress the wheel or replace if severely worn. Adjust machine settings according to valve type. Ensure adequate coolant flow. Check machine for loose components or worn bearings.
Excessive wheel wear	Aggressive cutting Lack of coolant Refacing incorrect material (not Stellite)	Reduce feed rate and depth of cut. Ensure proper coolant application. Confirm valve material is Stellite; this wheel is specifically for Stellite valves.
Wheel not running true	Improper installation Damaged spindle or flange Damaged wheel	Re-install the wheel, ensuring it is flush and securely tightened. Inspect machine spindle and flange for damage. Replace the wheel if it is physically damaged.
