Disassembly in general<br />
Maintenance<br />
The standard drawings and part lists do not include any detailed data about the<br />
type and dimensions of the fixing elements, etc.; thus, when you dismantle the<br />
<strong>motor</strong>, you should make a note of where the parts belong and mark them so that<br />
they can be easily re-assembled.<br />
Note<br />
Pay attention to the correct assignment and mounting position of the parts (such as<br />
bearings, sealing rings, pressure springs, spring washers, covers with different<br />
centering length).<br />
When you dismantle the <strong>motor</strong>, make a note of where the parts belong and mark<br />
them so that they can be easily re-assembled.<br />
Before beginning dismantling, check that the housing and the N-end bearing end<br />
shield are marked with respect to each other; if not, apply suitable markings (e.g.<br />
shallow chisel notches). The correct positioning of the brush rocker with respect to<br />
the bearing end shield and stator housing is important because of the adjustment<br />
of the neutral zone.<br />
When dismantling the bearing shield on the D-end take care that the windings<br />
protruding from the rotor housing are not damaged.Use jack screws to<br />
disassemble parts attached to the <strong>motor</strong> shaft. Before you pull-off screwed parts<br />
and components, replace two of the fixing screws in the top of the parts to be<br />
removed by long bolts or stud bolts, so that the parts are still supported after they<br />
have been removed.<br />
Note<br />
Motors with vertical designs can be dismantled in the horizontal position.<br />

6.3.3 Disassembling the bearings<br />
Disassembly<br />
Especially if the same bearing size is used on the D-end and N-end, pay attention<br />
to the correct assignment of components when dismantling (bearings, pressure<br />
springs, equalizing rings, covers with different centering length, etc.). The parts<br />
must be labeled when they are removed so that they can be correctly assigned<br />
again.<br />
