OTHER INFORMATION :
Caution: KSB solenoid should be connected (12 V) while calibrating the pump at all points except where specifically
indicated.
PROCEDURE FOR SETTING OF LOAD DEPENDENT PORT CLOSSING (LFB)
- Adjusting governor shaft: (See 9.1 and 9.7 of VE pump Repair & Testing booklet )
Before start of calibration, screw-in governor shaft until there is a gap of approximately 3 mm from the housing flange
to the end face of governor shaft. Then calibrate pump as per calibration chart .(from 1.1 to 1.6)
- Setting load dependent port closing operation 1.7.
Loosen the lock nut of the governor shaft. Run the test bench at the specified speed (as per 1.7). Keep the control
lever in maximum position. Screw-out governor shaft slowly till the vane pump pressurebegins to fall. Then screw-in
governor shaft again by 1/8 of a turn. Lock the governor shaft by tightening the lock nut to the specified torque.
