8.4 Reassembly
Perform the operations exactly in the reverse order, replacing all the O-Rings and
gaskets. When reassembling the cylinders, position the feed holes in the direction of the
transverse axis of the pump.
To replace the oil seals, use the protection sleeves that are available on request.
Add SAE 40 oil from the tank.
For screw tightening torques, see table torques tab.
8.5 Air bleeding
When the oil is full and the tank is open, tilt the pump according to its transverse axis,
slowly rotating the shaft. You will notice air bubbles coming out of the pump casing.
Keep topped up and continue the maneuver until no more air comes out. At this point
the pump is ready. Run it for a few minutes without pressure and top up with oil if
necessary.
(See Annex A)
Screw in the oil cap (with diaphragm where provided).
