15. To protect the armature finish and 

 commutator surface, place some 

 0.005-inch-thick plastic strips 

 (Mylar) inside the field. They 

 should extend above the armature 

 for grasping and removal after 

 motor installation. 



16. Bend the brush springs very carefully so that they remain as shown. Avoid 

 distorting. The original spring position is shown on the opposite page. 

 Position one set of brushes on the commutator, then gently compress the 

 remaining brush springs and slide them onto the commutator. The brushes 

 have to contact the commutator along the entire length of the brush. If 

 the brushes are canted, distorted, or shifted, remove the brushring gently 

 and bend the brush springs as necessary. Proceed until they fit cor- 

 rectly and then remove the brushring before proceeding in the assembly.
