Regulated Pressure Circuits
The regulated circuit is supplied by the front dual gear pump. The pump flow passes through the regulated circuit
filter housing and onto the priority regulator valve. The pressure regulator portion of the valve maintains the
regulated pressure at 22.4 to 24.5 bar (325 to 355 PSI).
The following components are supplied by the regulated circuit: speed transmission powershift valve, odd/even
transmission powershift valve (includes creep and park brake), range transmission powershift valve (includes
FWD), PTO/differential lock valve, master clutch inching valve, brake valve, hitch valve pilot pressure, remote valve
pilot pressure and FWD clutch supply.
