7.9.2 Assembling bearing
!
Make sure your working environment is clean and leave the bearings in their
original packing until you are ready to mount them.
1 Clean the interior of the bearing bracket properly.
2 Mount the NILOS-Rings (2310 and 2320) on the pump shaft. Make sure they are in
the right place and position.
3 If possible, preheat the bearings to 90°C before mounting them on the pump shaft.
The cylindrical roller bearing (2250) is fitted at the impeller side. The angular contact
ball bearings are fitted in O-position on the drive side. Make sure that all bearings are
straight on the pump shaft.
!
If preheating is not possible: never knock directly on the bearing! Use a
mounting bush which is positioned against the inner raceway of the bearing
and a normal hammer. A soft hammer may loose splinters which might
damage the bearing.
4 Fit the adjusting ring (2340) and fit the outer circlip (2360).
5 Grease the bearings. See paragraph 10.1 "Recommended greases" for
recommended grease types.
6 Press the bearing holder (2240) over the two angular contact bearings and fit the
inner circlip (2300) in the bearing holder. Make sure the inner circlip falls into the
groove.
7 Mount the shaft with the bearings into the bearing bracket from the motor side. Knock
the shaft end on the coupling side until the first bearing (2250) slides through the
bearing boring.
8 Carefully knock the pump shaft further into the bearing bracket until the bearing
holder (2240) is completely inside the bearing bracket. The pump shaft with the
bearings has to go straight into the bearing bracket.
9 Mount the bearing cover (2110) and the splash ring (2220).
10 Mount the set screws (1930) and the Allen screws (2810) and adjust the axial play as
described in 7.9.
11 Mount the self-priming part and the impeller as described in paragraph 7.8 "Shaft
sealing" and paragraph 7.7.2 "Mounting the impeller".
