23. Connect the brushring, as shown, 

 with the two wires which stick 

 out of the inner part of the 

 inner housing. Secure and in- 

 sulate the soldered joints with 

 heat-shrinkable tubing. Make 

 sure that the wires are long 

 enough so that it is possible to 

 repeat this procedure in case 

 the replacement of motor parts 

 is necessary. Make sure also 

 that the wires don't touch the 

 brush springs or the armature 

 when assembled. 



24. Put the brushring on the armature 

 by setting one set of brushes on 

 the commutator and gently com- 

 pressing the remaining brush 

 springs and sliding them onto 

 the commutator. 



NOTE: The commutator should remain 

 clean of fingerprints and scratches. 

 All possible precautions should be 

 taken to prevent silicone contami- 

 nation of the commutator or the 

 brushes. 



25. Put Loctite 290 adhesive/sealant 

 on the thread of the two counter- 

 sunk screws and secure the 

 brushring. 



22. Bend the brush springs yery 

 carefully so that they remain 

 like the pair of brushes pointed 

 out in the picture. Avoid dis- 

 torting. The original spring 

 position is shown on the oppo- 

 site pair of brushes. Position 

 one set of brushes on the com- 

 mutator, then gently compress 

 the remaining brush springs and 

 slide them onto the commutator. 

 The brushes have to contact the 

 commutator along the whole length 

 of the brush. If the brushes are 

 canted, di stored, or shifted, re- 

 move the brushring gently and 

 bend the brush springs as neces- 

 sary. Proceed until they fit 

 correctly and then remove the 

 brushring before proceeding in 

 the assembly.
