Pump Control Disassembly For Cleaning
NOTE: If the Function Pump does not perform correctly after
following the pre-start start-up procedures, it is possible that a
contaminate particle has lodged in the pump control prevent-
ing proper operation. The pump control’s internal parts are
not provided as spare parts due to the close tolerances
required between the mating parts. However, the control can
be disassembled, cleaned and placed back in service should
the only problem prove to be contamination. Disassembly,
inspection, cleaning and reassembly MUST BE done in a clean
well-illuminated area.
Pump Control removal:
1.
Disconnect plug the hose attached to the pump control
Port ”X”.
2.
Remove the four (4) socket head cap screws that attach
the control to the pump. Insure that the three (3) ”0”-
rings are also removed with the control.
3.
Hydraulic fluid may drip from the pump. Wiping the sur-
face clean and installing some adhesive tape should pre-
vent oil from seeping from the pump control.
4.
Work on a clean, lint free area.
NOTE:
The pump control can be equipped with either O-rings or a
sealing plate. These components are NOT interchangeable.
5.
Remove the three (3) ”0”-rings (Parker # 2-011, Viton 90
shore)
6.
Remove both the adjustment hex caps and bonded seal
rings. (17 mm wrench)
7.
Remove both the adjustment lock nuts and bonded seal
rings. (17 mm wrench)
8.
Remove both the adjusting screws. (3-mm Allen
wrench)
9.
Remove the spring cover hex cap for the ”outer” flow
regulation adjustment this requires a 19-mm wrench.
