Honda GL1000/1100 starter motor Removal/ Over haul Manual

1. Remove the three long bolts that hold the sections together and separate them. Be careful as there are a series of flat thrust washers on each end of the armature (located in the middle section). 2. The end cap basically performs no function other than to cover the brush plate and commutator area as well as center the armature shaft in a pressed in bushing located in the end of the cap. 3. The drive end contains the reduction gearing and if need be, can be disassembled to replace the bearing. This is extremely unlikely. The shaft should turn freely and normally only requires a cleaning and grease application. If the bearing in fact needs replacing, simply remove the “C” clips on either end, drive out the bearing and reinstall with an appropriate size replacement. Any decent auto parts / industrial supply should be able to supply the correct bearing. 4. Remove the brush plate from the end of the center section by removing the screw at the one brush connection. Before removing the brushes, note that one of them has an insulating sleeve over the braided wire. The replacement must go in the same brush holder. Remove the brushes and replace if necessary and clean the brush plate. ** Brake Cleaner is a good general cleaner for this entire job. 5. Remove the thrust washers from brush plate end of the armature. Count them and ensure they go back on the correct way. 6. The end of the center section that had the drive end on it has a circular plate covering it with a short splined shaft protruding through the plate. Drive the plate out by tapping the opposite end of the section on the shaft – just lightly with a rubber hammer or piece of wood to protect the shaft. Once the plate is out, remove the armature from the section. You will find more thrust washers at this end. Make sure they go back on correctly. 7. In the center of the center section there are four large Philips screws. These hold in the field coils found within the housing. Using an “impact driver”, loosen the four screws that go around the circumference of the center section and remove them. Remove the 10mm nut for the battery connection and the accompanying fiber insulating washers. With the screws and nut removed, the entire field coil assembly should withdraw entirely from the housing. There will be four (4) metal plates that the screws mounted into come falling out. They are easily replaced into the field coils when you slide it back into the housing. Do not be alarmed that you suddenly have four loose metal parts. 8. With everything out of the housing, thoroughly clean everything using the Brake Cleaner. Although the cleaner will dry without leaving a film, it is suggested that the components be dried with compressed air. 9. Get some extremely fine steel wool (“000″ of even “0000″ is better) and gently clean the metal surfaces or bars of the armature and the commutator. Blow with compressed air. 10. Using a volt/ohmeter, test for continuity between pairs of armature bars (the long ones). There should be continuity between the pairs around the entire circumference.
