Brush spring tension should be 44.5 to 49 N (10-11 lbs). If not, replace the springs before proceeding.
5. O-ring seal.
Important
^
The O-ring seal can easily be damaged during installation of the commutator end frame. To prevent such damage, install the O-ring seal as
described in the following steps:
A. Install the O-ring seal on the frame, field, and brush holder group so that it is against the shoulder on the field frame that will abut the
commutator end frame when installed. This is the normal installed position of the O-ring seal.
B. Carefully roll the O-ring seal out of its normal installed position up onto the major outer diameter of the field frame. Allow the seal to
remain in this position until the commutator end frame is partially installed.
