Abstract
A pre-adjusted control module comprises a bracket assembly adapted for attachment to a support structure of a construction vehicle. A control lever is pivotally mounted within the bracket assembly along with a bellcrank having a roller mounted on a first arm thereof. The roller is adapted to selectively engage either one of two notches formed on a lower end of the control lever and is biased in that direction by a tension coil spring connected between the bracket assembly and a second arm of the bellcrank. A control rod is reciprocally mounted in the bracket assembly and has its first end pivotally connected to the control lever and is adapted to have its second end connected to a self-centering valve spool of a directional control valve. A preadjusted sensing means, including a compression coil spring, is connected between the bracket assembly and the control rod to alert the operator upon approach of one of the two detent positions of the control lever, as effected by engagement of the roller with one of the two notches formed on the control lever.
