3.
After removing the spacer fixing bolts from the side of the already
installed magnetic way yoke, firmly hold the other magnetic way yoke
onto the positioning step, while firmly tightening the bolts. Make sure
that the magnetic way yokes do not slip into the path of the moving coil.
4.
Unscrew the rest of the spacer fixing bolts to remove the spacer. Check
where the spacer was fixed to see if there are any mounting holes. If
there are, insert bolts into them and tighten the bolts.
5.
Mount the moving coil. For details, refer to (2)Moving Coil Installation.
Note: This concludes the procedure if there is only one magnetic way.
6.
Place the second magnetic way in line with and at least 30 mm away
from the first magnetic way.
7.
Press the second magnetic way against the first magnetic way and
secure it with screws. Perform steps 1 through 4 to secure the magnetic
way with bolts. The magnetic attraction will pull the magnetic ways
together. Be careful not to get your fingers caught between the magnetic
ways.
8.
Use the same procedure to install the third and later magnetic ways as
you used for the second magnetic way.
