Brush Housing Final Assembly Tips
It is easier to install the brush housing assembly by sliding
the rotor assembly completely out of the other end of the
motor housing, then attach the brush housing first. After
the brush housing is installed look into the motor housing
from the opposite end to check that the positive (+) post
wires and static winding wires are positioned, not to block
the holes for the motor mounting bolts, inside the motor
housing.
After final assembly of the brush housing check that all
brush terminal screws are tight and the brush springs are
positioned properly before mounting the motor to the
pump/motor end head.
Brush Final Positioning
ONCE THE ROTOR ASSEMBLY IS IN PLACE, REMEMBER TO
PUSH EACH BRUSH DOWN UNTIL THE BRUSH FACE IS IN
CONTACT WITH THE COMMUTATOR ON THE ROTOR SHAFT
AND THE BRUSH SPRING IS PUSHING DOWN ON TOP OF
THE BRUSH.
