Pump compartment (23) Locknut (24) Setscrew (25) Locknut (26) SetscrewAdjust the flow of the upper pump.
Loosen locknut (23) .
Turning setscrew (24) clockwise will increase the output flow of the pump. Turning setscrew (24) counterclockwise will decrease the output flow of the pump. A 1/4 turn of setscrew (24) will change the output flow of the pump at the following pressures.
The pressure range of the first regulator spring is 15000 kPa (2200 psi) to 23400 kPa (3400 psi). Output flow of the pump will change approximately 22 L/min (5.8 US gpm) if the output flow is adjusted in this pressure range.
The pressure range of the second regulator spring is 23400 kPa (3400 psi) to 34300 kPa (4950 psi). Output flow of the pump will change approximately 8 L/min (2.1 US gpm) if the output flow is adjusted in this pressure range.
Tighten locknut (23) to a torque of 12 3 N m (9 2 lb ft).
Adjust the lower pump. Use locknut (25) and setscrew (26) instead of locknut (23) and setscrew (24) to adjust the lower pump. Repeat Steps 1 through 3.Adjustment of the Maximum Output Flow of the Pump
Illustration 2 g00507930
Adjust the maximum output flow of the upper pump.
Loosen locknut (27) .
In order to adjust maximum output flow, turn setscrew (28). Turning setscrew (28) clockwise will decrease the maximum output flow of the pump. Turning setscrew (28) counterclockwise will increase the maximum output flow of the pump. When setscrew (28) is turned by 90 degrees, the flow changes approximately 1.5 L/min (0.4 US gpm).
Tighten locknut (27) to a torque of 55 10 N m (41 7 lb ft).
Adjust the maximum output flow of the lower pump. Use locknut (29) and setscrew (30) instead of locknut (27) and setscrew (28). Repeat Steps 1 through 3.
