Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.
Press the 72T Rotation Gear in by hand. If necessary, use a dead blow hammer to lightly tap it in.
The Drive Shaft must be installed through the bottom side of the 3/8” ThunderHex bearing.
The Wheel Module Drive Shaft was updated to have a shoulder in order to get rid of the 3/8" Snapring. If your shaft does not have a shoulder, retain the 15T Bevel Gear and 3D Printed Bevel Gear Spacer with a 3/8" Snapring.
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.
If you ordered your Wheel Module Forks after 5/16/2023, make sure an updated Wheel Module Fork is used on the side with the 15T Bevel Gear. The updated Wheel Module Fork will have a pocket designed to fit a 1/4-20 Nut machined into the outside face.
The Main Drive Shaft and corresponding gear should be installed before the 3D Printed Rotation Pulley. Use the #4-40 x 3/4”L bolts to install the 3D Printed Rotation Pulley.
The 3D Printed Rotation Pulley was updated to strengthen the part and allow for longer bolts. If your 3D Printed Rotation Pulley does not have a step at the bottom of the integrated spacers that nests in the 72T Main Rotation Gear, then install the pulley using #4-40 x 3/4"L bolts.
Do NOT overtighten the #4-40 bolts, as this will crush the 3d printed part.
The #10-32 x 1-1/4"L Bolts will go through the 1/2"L Spacers and tap directly into the Falcon 500 Motors. The assembled plates with bearings from Step 4 must be installed with the flanges of the bearings facing the Top Plate.
The Drive Motor and Rotation Motor can be assembled in any order. However, they must both be installed in the way shown in the images below before moving on.
