Information:

Introduction
The proportional reducing valve for the power shift pressure is located on the main pump housing. The proportional reducing valve sends the reduced pilot oil pressure to the regulators at the idler pump and the drive pump. The output flow of the idler pump and the drive pump is controlled in accordance with the power shift pressure. Power shift pressure is controlled by the machine ECM.Preliminary Test
Testing and Adjusting, "Relief Valve (Pilot) - Test and Adjust"Required Tools
