If the brush holder (1) must be loosened or re-
moved from the end frame for repairs, the brush
holder must be installed again in the same position.
See Figure 7. Make alignment marks between the
brush holder and the end frame before the brush
mounting plate (4) is released. The brush holder
must be installed again in the same position.
If a new brush holder must be installed, there will
not be an alignment mark on the new brush holder.
Make an alignment mark on end frame with a refer-
ence point on brush holder that must be removed.
Install new brush holder so reference point and
alignment mark are aligned. The new brush holder
must be installed in the same position as the old
holder so the timing will be correct.
