  1. Separate the two halves of the solution pump housing.
  2. Leave the base of the pump in the base unit and the drive belt attached.
  3. A 15 mm six point socket will slip snugly over the broken half of the flex joint attached to the pump shaft.
  4. Using an impact wrench, spin the broken part out of the threads in the pump shaft (turning it counter clockwise).
  5. Remove the stator and auger from the other half of the housing.
  6. Clamp the auger in a padded vise and use the 15 mm socket and impact wrench to remove the other broken half of the flex joint from the auger (turning the socket counter clockwise).
  7. The repair can be accomplished in the field by using a soclet extention or two and striking the ratchet handle sharply with a hammer to remove the broken part from the pump shaft.
  8. The other half can be removed from the auger by the same method. But leave the auger in the stator while striking the ratchet handle sharply with a hammer.
  9. Got dirty hands from doing this? Booster is as good a hand cleaner as any you will find in an auto parts store. Use it straight.
