Hello,

We are having trouble getting one of our encoders installed onto a Toughbox. Normally, the codewheel of the encoder installs on to the shaft well and sort of "clicks" on, however with one of our Toughboxes the codewheel slides on and doesn't stay secure at all. We have tried different wheels that work fine on our other Toughboxes so we are pretty sure it is some kind of problem with the shaft. Does anyone have any idea what this might be, and if we have to get a new shaft from AndyMark, what part it is?

Thanks
