# Steps 5-8

{% 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 5

Press the 66T Rotation Gear in by hand. If necessary, use a dead blow hammer to lightly tap it in. 

The Bevel Gear Shaft must be installed through the bottom side of the 3/8” Rounded Hex bearing.

{% hint style="info" %}
The Thrust Bushing will be temporarily shipped as a printed component.
{% endhint %}

## Step 6

The 1/4” ID x 1/2” 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 1.5”L bolts to install both forks into the module.

## Step 7

&#x20;Use the #4-40 x 7/8”L bolts to install the 3D Printed Rotation Pulley. The step at the bottom of the 3D printed Rotation Pulley should sit flat with the 66T Main Rotation Gear.

{% hint style="warning" %}
Do NOT overtighten the #4-40 bolts, as this will crush the 3d printed part.
{% endhint %}

## Step 8

The Kraken X60 motor is installed using #10-32 x 1/2”L bolts. The 775pro is mounted using the M4 x 12mm L bolts.&#x20;

{% hint style="info" %}
The Rotation Pinion should be pressed onto the motor prior to mounting.

If the Neo 550 is being used as a replacement for the 775pro, use the recommended M3 x 10mm L bolts.
{% endhint %}

| Ratio Option | Drive Pinion |
| ------------ | ------------ |
| 6.00:1       | 12t          |
| 5.54:1       | 13t          |
| 5.14:1       | 14t          |
