DAMPED CONTROL HEAD ADJUSTMENT - Continued
6.
Loosen locknut (Figure 19, Item 2) approximately one-half turn.
7.
While holding locknut (Figure 19, Item 2), turn damped adjustment screw (Figure 19, Item 1) until approximately
seven threads are exposed beyond locknut (Figure 19, Item 2). Tighten locknut (Figure 19, Item 2).
8.
Start roller and set propel control lever to LOW range (TM 5-3895-379-10).
NOTE
Time rear drum for 10 revolutions in forward direction.
9.
Move propel control lever forward (TM 5-3895-379-10) until pressure is at 175 psi (1 200 kPa).
NOTE
Time rear drum for 10 revolutions in reverse direction.
10.
Move propel control lever rearward (TM 5-3895-379-10) until pressure is at 175 psi (1 200 kPa).
NOTE
If times vary more than 10 percent, more adjustment is necessary.
11.
Compare times recorded in Steps (9) and (10).
NOTE
To decrease the reverse drum speed in relation to forward drum speed, screw dampen
adjuster clockwise. To increase the reverse drum speed in relation to forward drum speed,
turn dampen adjuster (Figure 19, Item 1) counterclockwise.
12.
Adjust damped adjustment screw (Figure 19, Item 1) as necessary until the speed variation between forward
and reverse is less than 10 percent.
