4-11. Linkage Adjustment.

a. Speed Selector Linkage. The linkage must be

adjusted so that operator's control is positioned to

correspond exactly to the detent positions of the speed

selector valve. With the linkage disconnected, place

both the selector valve and the operator's control in

the neutral position. Adjust the linkage so that it can

be freely connected without moving the valve or the

control. Then try the control in each speed range

position. Make minor adjustments, if necessary, to

insure that the selector valve detent seats at every

speed range position of the operator's control.

b. Forward-Reverse Linkage. The forward and

reverse control linkage must be adjusted so that the

neutral, forward and reverse detent positions of the

valve correspond exactly with those of the operator's

control. This adjustment is made in a manner similar

to the adjustment of the speed selector linkage ( a

above).

c. Inching Control Linkage. Inching is controlled

by the inching pedal which is linked to the inching con-

trol valve in the transmission control valve. The

linkage must be adjusted so that 0 to 16 pounds of

pressure on the pedal results in only 0.0 to 0.10 inch of
