Modified Alignment Adjustment
When a machine is equipped with modified align-
ment the tower box is located on the side of the tower
with a mechanical linkage between the tower box and
the control bar.
NOTE
• All adjustments shown are made from the
tower box side of drive unit.
1. From the tower box side of drive unit, loosen the
jam nut at each end of the connection rod. See
Figures 88-1 and 88-2.
2. To adjust the distance between the control bar
and the switch pivot arm, rotate the connection
rod clockwise or counter-clockwise no more than
1/8 of a turn at one time. See Figures 88-1 and
88-2, and the adjustment chart below.
