4. Installation (Setup)

Replacing the ground drive belt requires careful attention to detail. Always refer to your specific Craftsman Model 917250810 service manual for the most accurate and detailed instructions.

1. Preparation: Ensure the tractor is on a level surface, engine is off, and all safety precautions (Section 2) are followed. Gather necessary tools, which may include wrenches, sockets, and a pry bar.
2. Access the Belt: Depending on your model, you may need to remove the mower deck, footrests, or other covers to gain access to the transmission and drive pulleys.
3. Relieve Tension: Locate the tensioning idler pulley and mechanism. Use a wrench or pry bar to relieve tension on the old belt, allowing it to be removed from the pulleys.
4. Remove Old Belt: Carefully route the old belt off all pulleys and remove it from the tractor. Note the routing path for the new belt. Taking a photo before removal can be helpful.
5. Install New Belt: Route the new Ground Drive Belt 197253 around the pulleys, following the exact path of the old belt. Ensure the belt is seated correctly in all pulley grooves.

6. Apply Tension: Re-engage the tensioning mechanism, ensuring the belt is taut but not overly tight. Proper tension is crucial for belt longevity and effective operation.
7. Reassemble: Reinstall any covers, footrests, or the mower deck that were removed.
8. Test: Reconnect the spark plug wire and battery. Start the engine and slowly engage the drive system to ensure the belt operates smoothly without slipping or unusual noises.

5. Operation

Once correctly installed, the Ground Drive Belt 197253 will facilitate the movement of your Craftsman lawn tractor. Engage the drive system according to your tractor's operating instructions. The belt should operate smoothly, providing consistent power to the wheels.

6. Maintenance

Regular inspection and maintenance will extend the life of your ground drive belt.

• Visual Inspection: Periodically inspect the belt for signs of wear, cracks, fraying, glazing, or damage. Replace the belt if any significant wear is observed.
• Cleanliness: Keep the belt and pulleys free from dirt, grass clippings, oil, and other debris. Debris can cause premature wear and slippage.
• Tension Check: Ensure the belt maintains proper tension. A loose belt can slip, causing inefficient operation and accelerated wear. An overly tight belt can strain bearings and reduce belt life.
• Storage: If the tractor is stored for an extended period, ensure the belt is clean and free from tension if possible, as per your tractor's manual.

7. Troubleshooting

If you encounter issues after installing the new ground drive belt, consider the following:

• Tractor Not Moving: Check if the belt is properly seated on all pulleys. Verify that the tension is correct. Ensure no obstructions are preventing belt movement.
• Squealing Noise: This often indicates a loose belt or glazed pulleys. Check and adjust belt tension. Clean pulleys if necessary.
• Belt Comes Off: Incorrect routing, improper tension, or worn pulleys can cause the belt to come off. Double-check the routing diagram and pulley condition.
• Incorrect Length: While this belt is specified for Craftsman Model 917250810, variations can occur. If the belt appears significantly too long or too short upon installation, double-check the part number against your tractor's requirements. A belt that is too long (e.g., 10 inches longer) will not provide proper tension and will not function correctly.
