1. Remove the puck with pallet from the MagneMover LITE transport system (see
Replace Pucks on page 399).
2. Remove the two M4 screws that secure the pallet and center plate to the magnet
assembly with a 2.5 mm Hex wrench and lift the pallet and center plate off the magnet
assembly as shown in Figure 7-48.
OPTIONAL
A. Remove the protective strip from the magnet assembly.
B. Clean the magnet assembly with Isopropyl alcohol to remove any residue.
C. Remove the backing from the new protective strip and place it on the magnet
assembly by centering the round hole at the end of the strip over one of the
threaded standoffs. Fold the strip around the bottom of the magnet assembly
and over the other standoff as shown in Figure 7-48. Press the strip into place
and use a burnisher, make sure that there are no bubbles.
3. If a new center plate is being installed, remove the backing and apply the glue dot to
the depression in the middle of the septum on the center plate as shown in Figure 7-48.
4. Attach the preload spacer to the glue dot.
5. If necessary, replace the spacers in the center plate as shown in Figure 7-48.
6. If necessary, replace the skis on the pallet as shown in Figure 7-48.
A. Remove the M4 screws that secure each ski with a 2.5 mm Hex wrench.
B. Clean the bottom surface of the pallet with Isopropyl alcohol to remove any
debris.
C. Install the new skis by locating them into the features on the bottom of the pal-
let.
D. Place two to three drops of Loctite 243 on the threads of each M4 x 8 mm flat
head screw. Secure the skis to the pallet with the two M4 x 8 mm flat head
screws and tighten to 0.8 N•m [7 in•lb].
7. Align the pallet with the spacers on the center plate and seat it into place.
8. Place two to three drops of Loctite 243 on the threads of each M4 x 20 mm flat head
screw. Secure the pallet to the magnet array with the two M4 x 20 mm flat head screws
and tighten to 0.8 N•m [7 in•lb].
The Loctite must cure for 2 hours at 22° C [72° F] before using the puck.
9. Replace the puck on the MM LITE transport system (see Replace Pucks on page 399).
