Caution	The rotating unit is adjusted axially by means of
	spacers 551.1. When reassembling the pump

after partial dismantling (bearing or seal replacement), the same spacer discs 551.1 must be mounted on the bearing side to reproduce the original rotor adjustment.

When dismantling keywayed nut 920.6, all relevant positions such as sequence and orientation of the contact face must be marked accordingly, to ensure identical reassembly (see also section 7.4.4).

-Undo nut 920.2 with lockwasher 931 or nut with locknut 920.6, depending on the pump size. To undo the nut, hold onto shaft with key 940.3.

-Pull off sleeve 520.1 with rolling element bearing(s) 320.1. (The shaft is centered in the sleeve without locking device.)

-Remove spacers 551.1, see text above.

Note: Pump versions V, Vx, E, Ex, F, Fx of sizes 32, 50,65 do not have a fixed bearing as this function is taken over by the motor bearings.

On pump versions Multitec V100, 125 and 150 the fixed bearing is located in the support lantern 342. Dismantling and installation shall be performed in analogy with the horizontal versions.
