We grind our own sausage and, last week, the grinder just cracked and stopped working. We ordered a new one and it will not spin. We tried our pelican head and have the same issue. It turns briefly and then stops though the main mixer still spins.
After some digging, we discovered that the screw inside the hub is coming loose (see attached). It’s reverse threaded. We tightened it up as best we could, but it keeps working itself loose after a second or two of using any attachment. Any thoughts? I thought about thread locking it, but am not sure if that screw is a failsafe feature to keep from tearing the internal gears? Any thoughts or ideas?
