MAINTENANCE

Machine Alignment
Floating Alignment Adjustment

When a machine is equipped with floating alignment
the tower box is located on the yoke and tower box
support with a mechanical linkage between the tower
box switch pivot arm and the yoke control rod. See
Figures 86-1 and 86-2.

NOTE

• All adjustments shown are made from the

tower box side of drive unit.

1. Adjust nuts #1 and #2 as needed. Refer to Fig-

ures 86-2 and 86-3.

CAUTION

• NEVER ADJUST NUTS #1 AND #2 MORE

THAN 1/4 TURN AT ONE TIME.

• ALWAYS RE-TIGHTEN THE JAM NUTS AND

ALLOW THE TOWER TO CYCLE TWICE
(START AND STOP) TO DETERMINE IF THE
TOWER IS STILL LEADING OR TRAILING.

2. Adjust nuts #1 and #2 until the tower is in align-

ment.

3. Continue the Three Tower Method of alignment

down the entire length of the machine making
adjustments as necessary to individual towers.
