You can use this hand reamer to repair Taylor freezer doors with draw valves that stick or do not move freely. Over time, some freezer doors become slightly warped. By running this reamer from the top of the freezer door through to the bottom (where the star cap is), you will true up the cavity and allow the draw valve to move freely again.
This works on most Taylor soft serve models including 321, 336, 339, 751, 754, 794, 8756, C706, C707, C712, C713, C716, C717, and many more models
