  • Page 24 A check of the condition of the oil can show whether there has been an increased leakage. Note! Air/oil mixture can be confused with water/oil mixture. Insert a tube (or hose) into the oil hole. Cover the top end of the tube and take up a little oil from the bottom. Change the oil if it contains too much water, i.e., is heavily emulsified (cream-like), or if the oil housing contains separated water. See "Changing the oil". Check again one week after changing the oil. If the oil contains too much water again, the fault may be: that an oil screw is not sufficiently tight. that the O-ring on an oil screw or its sealing surface is damaged. that the mechanical seal is damaged. Contact a Xylem service shop. Oil quantity 2052 0.2 litres (0.21 US quarts) 2066 0.75 litres (0.79 US quarts) 2102 1.4 litres (1.48 US quarts) WARNING! If the seal leaks, the oil casing may be under pressure. Hold a rag over the oil casing screw in order to prevent splatter.

    Installation, care and maintenance 2052, 2066, 2102 Changing the oil Oil casing WARNING! If the seal leaks, the oil casing may be under pressure. Hold a rag over the oil screw to prevent splatter. Unscrew the nuts and remove the strainer (only 2052). Unscrew the oil screw. Turn the pump so that the oil hole faces down w ards. It is easier to drain the oil if another oil screw is also re- moved.

Do not pry off the impeller, since it can easily be dam- aged. If it is necessary to change the diffuser, the oil has to drained away. Only 2102 Then remove the studs and the diffuser. Installing the impeller Make sure that the end of the shaft is clean and free of burrs. Polish off any flaws with fine emery cloth.

Tightening torque: 2052 30 Nm 2066 30 Nm 2102 30 Nm Place the second impeller nut on the shaft and tighten it (= 2052). The clearance between the impeller and the oil casing bottom should be 0.2 - 0.3 mm when the impeller is tight- ened. The clearance can be adjusted with the adjusting washers.
