              Reassembly Tricks
  • When reinstalling this outer nut cover it will appear like it doesn’t fit . It needs to be attached by evenly screwing in the bolts at the same time. example: screw in one bolt half way, screw in the other 2 half way, repeat until secure.
  • Beware you may have difficulty removing roller arms from the shaft, i assure you it will come off. Sometimes its a matter of spinning the kneading motor until you have a enough space. See Step 3
  • Please note on your mechanism you may have to cut zip ties to free up the roller arm cable. please apply new zip ties as necessary.
