servo control 19 of the main pump 18 movement between the cam plate 68 and 79 is provided solely between the slot 69 and a detent pin 80 on the lower plate 79 with this arrangement it can be seen that when the hand lever 60 is pulled back into the free wheel detent position slot 64 control cable 65 will pivot the plate 68 moving the spool of the brake valve to the left thus allowing charge pressure to reach the main control valve 24 in the alternative return of the cam 68 to a centered brake on position cannot occur until the servo mechanism 19 has returned the pump to neutral position the spool of the main control valve is controlled by a cable 82 when the hand lever 60 is in the center position the spool of the main control valve 24 is centered as shown in fig1 while the cam follower 72 of the brake valve was in the detent position 70 the brake on the winch drum remained set because no control fluid could move either the actuator 56 or 55 this occurred even though the spool of the main control valve 76 was centered enabling energization of the actuator 55 and 56 if control fluid pressure were available by having shifted out of the detent position and thus shifted the spool of the brake valve 74 to the left the control fluid pressure does reach the actuators 55 and 56 extending them and placing the winch into the freewheel position in all shifting positions the hand lever must pass through the.
