Port Plug Update:
Subject:
On Machete and Brahma pumps utilizing the new design Servo Solenoid Valve assembly, An incor- rect port plug was installed in the port next to the solenoid Valve. This incorrect port plug does not allow oil trapped on the back side of the servo piston to escape to tank, resulting in incomplete shifting of the servo piston and thus incomplete stroke of the pump, causing a notice- able decrease in blade speed and performance. Pumps that need updating can be externally identified by the wire exit direction on the solenoid coil, a rectangular wire

connection point on the solenoid coil, and a raised button on the port plug as shown in figure 1.
