6. Check that the cross roller bearing is centered in the 2 v-rails by the following
method:
a) Center the retainer plate assembly on the embroidery head v-rail.
b) Carefully insert a solid instrument, such as a straight allen wrench, into the
opening at one end where the two v-rails join. Insert the instrument until
it contacts the cross roller bearing. Do not force it any further.
c) Mark the position of the instrument at the end of the embroidery head
v-rail, when the instrument is inserted to where it contacts the cross roller
bearing.
d) Repeat this on the other side of the v-rails and compare the two marks.
They should be very close to the same - within about 3/32 of an inch.
e) Repeat the above procedure for centering the cross roller bearing until the
checking verifies it is within the proper tolerance.
