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. 57.
