DC motor - Siemens, s.r.o.

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

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