Step 6-9

Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

Step 6

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.

The Wheel Module Drive Shaft was updated to get rid of the #8-32 bolt and printed cap. If your shaft has a tapped hole, refer to the v1 Drive Shaft image below. If your shaft doesn't have a tapped hole, refer to the v2 Drive Shaft image below.

Step 7

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.

Step 8

Use the #4-40 x .375”L bolts to install the Gear Cartridge Column. Then slide the Cartridge and Bearing Spacer on top.

The Steel Cartridge will already have the 15mm ID x 24mm OD bearings pressed in.

The Gear Cartridge Column should be flush with the Rotation Gear.

Step 9

The #10-32 x 1-1/4"L Bolts will go through the 1/2"L Spacers and tap directly into the Kraken X60 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.

For the Drive Pinion refer back to the Ratio Options page.
