The following is a general procedure for all vans, and may vary slightly depending on model and series.

  1. Disconnect the battery ground cable at the battery.
  2.  
  3. Raise and support the vehicle.
  4.  
  5. Disconnect and tag all wires at the solenoid terminal.
  6.  

1975 and later starters do not require the R terminal. The High Energy Ignition System does not need a cable from solenoid to ignition coil.

  1. Reinstall all nuts as soon as they are removed, since the thread sizes are different.
  2.  
  3. Remove the front bracket from the starter and the two mounting bolts. On engines with a solenoid heat shield, remove the front bracket upper bolt and detach the bracket from the starter.
  4.  
  5. Remove the front bracket bolt or nut. Lower the starter front end first, and then remove the unit from the van.
  6.  
  7. Reverse the removal procedures to install the starter. Torque the two mounting bolts to 25-35 ft. lbs. (33-47 Nm).

  10.  
  11. Slide a small piece of 1 / 2 in. (12.7mm) pipe over the end of the shaft so the end of the pipe butts against the edge of the retainer. Carefully tap the end of the pipe with a hammer, driving the retainer towards the armature end of the snapring.
  12.  
  13. Remove the snapring from the groove.
  14.  
  15. Slide the retainer and clutch off the shaft.
