(1) Remove cotter pins and yoke pins

attaching yokes to control levers or to control valve.

(2) Loosen yoke lock nuts and adjust yokes

on rods to shorten or lengthen linkage.

(3) Linkage should be adjusted to allow the

least amount of free play. When adjustment is complete,

control valve plungers must be in the neutral position

when levers are released.

c. Switch Adjustment. Switch actuators must be

adjusted to have switch open when plungers are in

neutral position. Adjustment must be such that the

actuators close the switch with little movement of the

control lever. Disconnect battery receptacle. Refer to

figure 4-37 and adjust switch and actuators as follows:

(1) Move control levers (fig. 4-36) as if

operating lift, tilt and side shift mechanisms. Switches

(fig. 4-37) should close with an audible click after little

movement.
