Step-by-Step Instructions:

1. Removing the Bottom Spindle Bearing

• Use an impact drill with the M24 socket to remove the four bolts securing the bottom spindle bearing (Part No. 1005).
• Ensure all bolts are completely removed before proceeding.

2. Loosening the Umbraco Bolts

• Locate the two 4mm Umbraco (hex) bolts securing the bearing in place.
• Use the M4 Umbraco key to loosen these bolts. This will allow you to push the bearing upwards on the shaft.

3. Loosening the Tension Bolts

• Identify the two tension bolts on either side of the spindle assembly.
• Using the M17 wrench, loosen both bolts. This will relieve tension from the belt.

4. Loosening the Motor Mount Bolts

• Locate the four bolts that secure the motor mount.
• Using the M17 wrench, loosen and remove these bolts to free the motor.

5. Adjusting the Belt

• While gently rotating the spindle, push the belt upwards. This will help release tension from the belt.

6. Tilting the Spindle Assembly

• Carefully tilt the spindle assembly sideways to create sufficient clearance for removing the belt.
• Once there is enough space, slide the belt out from the assembly.

7. Reassembly

• After removing the old belt, follow the above steps in reverse order to reinstall the new spindle belt.

Spindle Belt Tensioning Guidelines:

• The belt should have some flexibility. When pressed inward, it should move approximately 1 centimeter to allow for proper tensioning.
