Washing the flow and safety valves of the GAZ-3110 power steering pump
Clean the outside of the pump from dirt
Drain the oil from the system (see “Replacing the GAZ-3110 power steering oil”)
Using a key set to “24”, unscrew the plug located above the pump outlet. (For clarity, shown with the pump removed.)
Remove the flow valve spring.
Remove the spool.
To prevent oil from leaking out and dirt from getting inside the pump, we install the plug in place.
Use a thin screwdriver to carefully remove the rubber seal from the spool.
Having wrapped the spool body in thin cardboard or a piece of emery cloth and carefully holding it in a vice, use a “10” wrench to unscrew the spool seat.
When releasing the spool body from the vice, hold it vertically so as not to lose small parts of the valve.
Remove the ball, guide rod and spring from the spool body.
We wash all parts in gasoline and blow with compressed air (from a pump or compressor).
Assemble the spool and install it in place in the reverse order.
