REMOVAL AND INSTALLATION



This procedure is to be performed with the alternator removed from the vehicle. The CS-130 alternators are non-serviceable and must be replaced as an assembly.

  1. Make scribe marks on the end housing frames to make reassembly easier.
  2.  
  3. Remove the 4 through-bolts and separate the end frame assembly from the rectifier end frame assembly.
  4.  
  5. Remove the 3 stator attaching nuts and remove the stator from the end frame.
  6.  
  7. Unsolder the connections, remove the 2 regulator attaching screws and separate the regulator and brush holder from the vehicle.
  8.  
  9. To install, assemble the regulator, brush holder and connector to the end frame. Securely solder the connection between the regulator and brush holder, and the connection between the regulator and brush strap.
  10.  
  11. Assemble the stator to the end frame.
  12.  
  13. Install the halves of the alternator, ensuring the end frames are aligned as previously removed. Secure the halves with the 4 through-bolts. After the alternator is assembled, remove the brush retainer.
