4. Installation

The following are general steps for replacing a bearing shaft. Specific procedures may vary depending on your Stiga SR 6665B Lawn Tractor model and cutting deck configuration. Always refer to your tractor's service manual for detailed instructions.

1. Preparation: Park the lawn tractor on a flat, stable surface. Engage the parking brake. Disconnect the spark plug wire and battery to prevent accidental starting.
2. Access the Cutting Deck: Carefully raise the front of the tractor or remove the cutting deck as per your tractor's manual to gain access to the spindle assembly.
3. Remove Old Shaft: Identify the worn or damaged bearing shaft. Loosen and remove any retaining bolts, nuts, or clips that secure the shaft within its housing or spindle assembly. You may need specialized tools to press out the old shaft.
4. Clean Area: Thoroughly clean the bearing housing and surrounding area, removing any debris, rust, or old grease.
5. Install New Shaft: Carefully insert the new SECURA Bearing Shaft into the clean housing. Ensure it is properly aligned. Use a press or appropriate tools to gently seat the shaft without damaging it or the housing. Do not use excessive force.
6. Secure Components: Reinstall all retaining bolts, nuts, and clips, tightening them to the torque specifications provided in your tractor's service manual.
7. Reassemble: Reattach the cutting deck (if removed) and reconnect all components.
8. Test: Before operating the tractor, manually rotate the blades to ensure smooth movement and proper clearance. Reconnect the spark plug wire and battery. Start the engine and test the cutting deck at a low speed in a safe area.

Important: Incorrect installation can lead to premature wear, equipment damage, or unsafe operation. If you are unsure, seek professional assistance.

5. Usage Considerations

The SECURA Bearing Shaft is a functional component designed to restore the performance of your Stiga SR 6665B Lawn Tractor's cutting deck. Once correctly installed, it facilitates the smooth rotation of the cutting blades.

• Proper Function: A correctly installed bearing shaft ensures the cutting blades spin freely and without excessive vibration, contributing to an even cut and reduced strain on the tractor's engine.
• Avoid Overloading: Do not attempt to cut grass that is excessively tall or wet, as this can put undue stress on the cutting deck components, including the bearing shaft.
• Regular Inspections: Periodically inspect the cutting deck for any signs of wear, looseness, or unusual noises, which could indicate issues with the bearing shaft or other components.

6. Maintenance

While the bearing shaft itself is a relatively low-maintenance component, its longevity is directly tied to the overall maintenance of your lawn tractor's cutting deck.

• Cleanliness: Regularly clean the underside of the cutting deck to prevent buildup of grass clippings and debris, which can cause imbalance and stress on bearings.
• Lubrication: If your spindle assembly has grease fittings, ensure they are lubricated according to your tractor's maintenance schedule. The bearing shaft itself may be sealed and not require direct lubrication.
• Inspect for Wear: During routine maintenance, check the bearing shaft for any signs of excessive play, rust, or damage. Replace if necessary.
• Blade Balance: Ensure cutting blades are sharp and balanced. Unbalanced blades can cause vibrations that accelerate bearing wear.

7. Troubleshooting Common Issues

For persistent issues, it is always best to consult a qualified lawn tractor service technician.
