The oil now becomes signal oil. Some of the signal oil flows through an orifice to spring chamber (17) that is behind flow control valve (19). Then, flow control valve (19) moves to the left. The remaining signal oil moves to resolver (11) and the signal oil flows through passage (13) to the previous control valve. Then, the signal oil flows to the inlet manifold. The inlet manifold sends signal oil to the compensator valve in order to upstroke the pump.The increased pump oil flows to inlet passage (18) and through metering slots (20) to chamber (21) and load check valve (23) opens. The oil through load check valve (23) flows to passage (22), around control valve spool (26), and out of passage (3) to the rod end of the lift cylinders. The bulldozer blade raises.Return oil from the head end of the lift cylinders comes through passage (5), around control valve spool (26), and through outlet passage (7) to the tank.Lower

This flow causes the pump to upstroke to pilot control pressure
