1. Tools needed: 7mm or 8mm socket depending on model, 12mm socket and 14mm deep socket ( helps
    to use grinder on 14mm socket to thin edge out ) Diesel Starter 14 & 17MM
  2. Remove cover from solenoid and remove plunger assembly.
  3. Use 12mm socket to remove nut from starter motor lead to solenoid.
  4. Use 14mm socket to remove nuts from battery and motor sides of solenoid then remove contacts,
    insulators and post from solenoid. Then clean dirt from inside of solenoid.
  5. Solenoid contact post on the motor side is attached to the starter contact. Secure contact in vise and
    gently tap post to remove from contact.
  6. Install new contacts into solenoid in reverse of removal. Take care to make sure that new solenoid
    contacts are level when you tighten the 14mm nut. If they aren't it will reduce the life of new contacts.
  7. Inspect solenoid plunger for wear. We recommend replacing solenoid plunger for maximum life but, if
    you reuse the old plunger make sure the surface is clean. Then reinstall plunger.
  8. Reinstall solenoid cap and bench test.
  9. Install on vehicle and you're READY TO ROLL!
