Ri3D 1.0 Winch, Shift-To-Neutral, Ratcheting GearBox CAD (UPDATED!)

This is update 1 of the CAD development of our Winch Gearbox. There are a few missing details, namely the screw for the dog shifter and the 3/8″ ratcheting wrench on the cluster shaft. I’ll attempt to model a wrench soon. There are additional spacers that can be removed depending on the width of the wrench you decide to use in this application.

This is also a slightly different version than the one we are using. I attempted to create this version from fully off the shelf parts. The only custom part is the Shaft which AndyMark will be carrying in about a week. The rest is standard Modulox or AndyMark shifter components. I’ll also create a CAD tutorial on how this goes together.

Also note, on the shifter side, a bearing block has been used with the thread holes drilled out for clearance.

/Edit Added Rev 2 with a wrench and some additional hardware. I would suggest confirming your ratchet wrench’s dimensions before utilizing this configuration.
