7.5 Disassembly and assembly Top Pull Out unit OH3
➢
The Top Pull Out unit and the electric motor of large pumps are too heavy to be lifted by
hand. Use appropriate hoisting equipment.
The pumps are designed with a Top Pull Out system. For that reason they are provided
with a "spacer"-coupling. The intermediate piece of this coupling can be removed. After
that the bearing bracket with the entire rotating part can be removed. This means that
almost the whole pump can be dismantled without having to detach the suction and
delivery piping. The motor remains in its position.
7.5.1 Disassembling the Top Pull Out unit OH3
1 Remove the guard (0270).
2 Remove the spacer.
3 Disconnect possible flushing and/or cooling lines.
4 Remove the nuts (0810) and washers (0805). Tighten alternately both bolts (0820)
until the pump cover (0110) is released.
5 Pull the entire bearing bracket (2100) from the pump casing. The entire bearing
bracket of large pumps is very heavy. Support it with a beam or hang it in a pulley
sling.
7.5.2 Assembling the Top Pull Out unit OH3
1 Fit a new gasket (0300) into the pump casing and fit the entire bearing bracket back
into the pump casing. Place washers (0805) and tighten the nuts (0810) crosswise.
For tightening moment of the nuts see paragraph 10.1.4 "Torques settings for nuts for
pump casing".
2 Reconnect the flushing and/or cooling lines. For tightening moment of the stud bolts
(2000) (2040) see paragraph 10.1.3 "Tightening moments stud bolts for drain and
seal flushing".
3 Fit the spacer of the spacer coupling.
4 Check the alignment of pump and motor shaft, see paragraph 3.4.3 "Alignment of the
coupling". If necessary, realign.
5 Place the guard (0270) on the coupling.
