How to Repair Broken Flex Joint
- Separate the two halves of the solution pump housing.
- Leave the base of the pump in the base unit and the drive belt attached.
- A 15 mm six point socket will slip snugly over the broken half of the flex joint attached to the pump shaft.
- Using an impact wrench, spin the broken part out of the threads in the pump shaft (turning it counter clockwise).
- Remove the stator and auger from the other half of the housing.
- 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).
- The repair can be accomplished in the field by using a socket extension or two and striking the ratchet handle sharply with a hammer to remove the broken part from the pump shaft.
- 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.
- 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.
