  4. Install the front endbell onto the magnet. Make sure all six remote latch pins are held by their remote latches.
  5. Check the gap between the endbell and the RF coil at the 12 o'clock, 3 o'clock, and 9 o'clock positions using a 3 mm and 4 mm hex wrench. The gap should be 3 mm to 4 mm. If the gap between the front endbell and RF coil is less than 3 mm or greater than 4 mm, adjustment is required.

  6. Front endbell gap adjustment
    1. Note the areas that need adjustment and determine how much adjustment is needed.
    2. Remove the front endbell and set aside.
    3. Loosen the nut on the standoffs that will be adjusted, typically those nearest the area where the gap is incorrect. You may need to remove additional screws.
    4. Insert a screwdriver in the nylon screw and turn clockwise to reduce the gap or counterclockwise to increase the gap.
    5. Tighten the silver nuts and reinstall the screws that were removed.
    6. Reinstall the endbell and recheck the gap. Repeat until the gap is 3 mm to 4 mm.
