# Step 6-9
{% hint style="success" %}
Vibra-TITE VC-3 Threadmate ([Vibra-TITE](https://wcproducts.com/products/threadlocker)) is recommended on all bolts that thread into a tapped hole.
{% endhint %}
## 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.
| Ratio | 2nd Stage Driven Gear |
| ----- | --------------------- |
| X1 | 18t |
| X2 | 16t |
| X3 | 14t |
{% hint style="info" %}
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.
{% endhint %}

## 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.
{% hint style="info" %}
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.
{% hint style="info" %}
The Steel Cartridge will already have the 15mm ID x 24mm OD bearings pressed in.
{% endhint %}
{% hint style="warning" %}
The Gear Cartridge Column should be flush with the Rotation Gear.
{% endhint %}
## 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.
{% hint style="info" %}
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.
{% endhint %}

For the Drive Pinion refer back to the [Ratio Options](https://docs.wcproducts.com/welcome/gearboxes/wcp-swerve-x/general-info/ratio-options) page.
