7. Locate the replacement magnet array and place flat on the work surface away from the
vehicle.
8. Place the previously removed shims on the top surface of the replacement magnet
array. Slide the shims around the array posts but do not allow the ends to extend
beyond the outer edges of the array.
NOTE: If the shims are removed, or additional shims added, the length of the screws
must be adjusted appropriately.

essary to make sure that they align with the vehicle.
10. Secure the array to the vehicle with the two M4 x 12 mm screws that were removed in
Step 4 with Loctite 243 and tighten each screw to 1.5 N•m [13 in•lb].
The Loctite must cure for 2 hours at 22° C [72° F] before using the vehicle.
11. Replace the vehicle, see Replace Precision Rail Vehicles on page 428.
12. Restart the path.
13. Dispose of the removed magnet array appropriately.
