Step 5-8
Vibra-TITE VC-3 Threadmate (Vibra-TITE) is recommended on all bolts that thread into a tapped hole.
Step 5
Press the 72T Rotation Gear in by hand. If necessary, use a dead blow hammer to lightly tap it in.
The Wheel Module Drive Shaft must be installed through the bottom side of the 3/8” Rounded Hex bearing.

Step 6
The 1/4” ID x 5/8” OD bearing can be pressed into the Wheel Module Fork by hand. Only the Fork that aligns with the Wheel Module Drive Shaft needs a bearing. Once the bearing is in place, use the #10-32 x 1 3/4”L bolts to install both forks into the module.
Step 7
The Main Drive Shaft and corresponding gear should be installed before the 3D Printed Rotation Pulley. Use the #4-40 x 7/8”L bolts to install the 3D Printed Rotation Pulley.

Do NOT overtighten the #4-40 bolts, as this will crush the 3d printed part.
Step 8
For the Non-Flipped configuration, the output shafts for the motors must be shortened for clearance. If you do not want to cut the shafts, we recommend installing the Motor Spacers.
For all configurations, the motors are installed using #10-32 x 1/2”L bolts. The pinions are bolted in using #10-32 x 1/2”L bolts.
When using the X3 Ratio Set for the Standard Configuration, the Drive Pinions on a 14T CD will collide with the Top Plate.
To prevent this, the options are:
1) (Recommended) The pinion can be cut shorter by a 1/16" and spaced down to the end of the motor shaft.
or
2) The hole can be drilled to 0.875" to provide necessary clearance for pinion.
