unit carrier frames.

rod to the #2 lift arm (Figure 9). Remove the
pivot rod and spring from the lift arm. Repeat the
procedure on the #1 and #3 lift arms.

brackets and U-bolts 15 inches behind the center line
of the pivot knuckle (Figure 10). On lift arms #1
and #5 the brackets should be rotated to the right 10
degrees from vertical (Figure 10). On lift arm #4
the bracket should be rotated to the left 10 degrees
from vertical (Figure 10).
2. On lift arms #2 and #3, position the brackets and
