When replacing the carbon motor brushes, replace the top and bottom for motor balance. Also, be extra careful when unscrewing the motor cap screws if they are the original Bakelite style. Use a proper-sized screwdriver and carefully turn the screwdriver without applying too much pressure or force because it can crack and break easily. Of course, should this happen, we also have
replacement motor cap screws available.
Motor Brushes will fit models 15-91, 201, 221, 222, and
most 401s.
