KoP ToughBox Mini and CIMs Problem/Solution

[Tom Line]

Turning it around in the gearbox suggests that the cim motor fasteners may be drilled / tapped off center. We've used minitoughboxes each of the last several years and not had that problem.

It was noted a couple days ago that one team saw differences between the Vexpro hex bearings and the AndyMark ones.

For those teams effected, are you using Andymark Hex shaft? AndyMark Bearings? Vexpro Cims? Finding a common factor might help.

I seem to recall that the end of the shaft on the CIM was not centered in the hole of the Toughbox mount plate. Could this be another sign that the CIM mounting holes are off either on the CIM or Toughbox?

One thing to keep in mind when assembling tough-boxes is that the hole for the CIM bore is not designed to be a pilot, as the tough-boxes are designed to use a 14T CIM Pinion. Because of this, it's possible to have a small amount of misalignment between the CIM output shaft and the true 'center' of the CIM mounting hole. I remember encountering an issue similar to this in either 2009 or 2010 and we found that it was best to not fully tighten down the CIM mounting screws until the gearbox had been checked to ensure proper rotation of everything.
