Assembling bearing
1 Clean the interior of the bearing bracket properly.
1 Subsequently fit the Nilos ring (2310), the inner circlip (2300), the Nilos ring (2320)
and the adjusting ring (2375) on the pump shaft. Make sure the Nilos rings are
positioned properly!
2 Preheat the angular contact ball bearings and the inner ring of the cylindrical roller
bearing and fit them onto the pump shaft. Make sure they are positioned straight on
the pump shaft and push them firmly against the shaft shoulder. The cylindrical roller
bearing (2250) is fitted at the impeller side. The angular contact ball bearings are
fitted
in O-position
at the drive side. Ensure that the bearings are fitted straight on
the pump shaft. The Nilos ring (2310) is now fixed between the pump shaft and the
inner ring of the cylindrical roller bearing.
Let the bearings cool down!
3 Fit the locking washer (2570) and screw the lock nut (2560) on the pump shaft.
Tighten the lock nut and lock it by knocking a lip of the locking washer into the
opening of the lock nut.
4 Fit the inner circlip (2300) into the bearing bracket (2100).
5 Fit the pump shaft with bearings, starting from the motor side, in the bearing bracket.
Knock at the shaft end at the coupling side until the foremost bearing (2260) slides
through the bearing bore. After each knock rotate the pump shaft one turn to prevent
bearing damage.
6 Fit the outer ring of the cylindrical roller bearing. This ring should go into the bearing
bracket
straight.
7 Check to ensure that the oil catchers (2120 and 2125) are undamaged. Replace
them if necessary.
8 Fit the bearing covers (2110 and 2115) and fix them with Allen screws (2810 and
2815).
9 Fit the deflector (2180 and 2220).
10 Fit the shaft seal and the impeller, see paragraph 7.8.3 "Mounting a cartridge seal"
