In the following text there are two types of starters covered. The direct drive type is used on the 8R-C, some 1972 18R-C, and some 20R engines. The other engines covered here including most of the 18R-C's have the gear reduction starters.

  1. Disconnect the negative battery cable.
  2.  
  3. Tag and disconnect all wiring leading from the starter.
  4.  
  5. Unscrew the two starter mounting bolts.
  6.  
  7. Remove the starter.

  5. Remove the solenoid. In order to unhook the solenoid from the starter drive lever, lift it up at the same time that you are pulling it out of the starter housing.
  6.  
  7. Installation is in the reverse order of removal. Make sure that the solenoid switch is properly engaged with the drive lever before tightening the mounting screws.

Brush Replacement
DIRECT DRIVE TYPE
  1. Remove the starter.
  2.  
  3. Remove the solenoid (magnetic switch).
  4.  
  5. Remove the two end frame cap mounting bolts and remove the end frame cap.
  6.  
  7. Remove the O-ring and lock plate from the armature shaft groove and then slide the shims off the shaft.
  8.  
  9. Unscrew the two long housing screws (they are found at the front of the starter) and carefully pull off the end plate.
  10.  
  11. Using a flat bladed tool, separate the brushes from the brush holder.
  12.  
  13. Slide the brush holder off of the armature shaft.
  14.  
  15. Crush the old brushes off of the copper braid and file away any remaining solder.
  16.  
  17. Fit the new brushes to the braid and spread the braid slightly.
  18.  

Use a soldering iron of at least 250 watts.

  1. Using a radio-grade solder, solder the brush to the braid. Grip the copper braid with flat pliers to prevent the solder from flowing down its length.
  2.  
  3. File off any extra solder and then repeat the procedure for the remaining three brushes.
  4.  
  5. Installation is in the reverse order of removal.
