If your Lucas starter has worn out and needs to be repaired, instead of replacing the starter, it may be possible for you to repair the part by removing and replacing the worn out brushes inside the commutator end plate. Removing the brushes in the starter is a job that can be done in about 30 minutes. You can remove the brushes yourself, saving you time and money.
Unfasten the two screws that hold the commutator end plate to the Lucas starter with a screwdriver and set the screws aside.
Pry the commutator end plate off the starter with a screwdriver and lift the plate up just enough to locate the field brushes inside the plate.
Detach the two field brushes from the brush box on the back of the end plate by manually and set the end plate down on a work surface.
Locate the main terminal stud on the commutator end plate and unfasten the nut with a nut driver.
Slide out the washer and insulator from the main terminal stud then remove the stud and second insulator from the end plate.
