# Getting Started

## Assembly Prep

Refer back to the  [Individual Components](/welcome/system-and-structure/wcp-stub-rollers/general-info/individual-components.md) page to ensure that all necessary parts are located before starting assembly steps.

#### Tools Required For Assembly

These tools are required for the assembly of the WCP Stub Rollers

* Snap Ring Pliers (For 1/2" Snap Rings)
* Allen Keys
  * 1/8"

## Assembly Instructions 

The following sections will cover the basic assembly instructions for the WCP Stub Rollers.

{% hint style="info" %}
The following section will use the Aluminum Stub Roller Hub (1-1/8" OD) for reference but assembly instructions are interchangeable for all the WCP Stub Roller configurations.
{% endhint %}

## Step 1

The 1/2" ID bearings will be installed as shown below. The bearings should be recessed into the Roller Hub.

{% hint style="warning" %}
Bearings may be a press fit. Use an arbor press to ensure the bearings are fully seated.
{% endhint %}

## Step 1B (Optional)

{% hint style="success" %}
This step is optional.
{% endhint %}

The inside bearing can be retained in the Roller Hub Assembly using a snap ring. This snap ring is not necessary and is only intended to be used when the rollers will be used with a shaft running throughout. This will prevent the bearing from backing out during use.&#x20;

{% hint style="info" %}
The optional Snap Ring is a 7/8" ID Internal Snap Ring ([McMaster P/N 99142A420](https://www.mcmaster.com/99142a420/)).
{% endhint %}

## Step 2

Insert the correct Stub Shaft into the Roller Hub assembly and secure this with the 1/2" Snap Ring. Refer back to the compatibility chart to ensure that the correct Stub Shaft is being used for the Roller Hub.

{% endtab %}

{% tab title="Compatibility Chart" %}

{% endtab %}
{% endtabs %}

## Step 3

Insert the assembled Stub Roller Hub Assembly into the Tube and secure using #10-32 x 1/4"L bolts.

<figure><img src="https://4135010533-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FZFpeyLzrE29cgyWyQDsF%2Fuploads%2FVJ2RAhlsgD5Jh1JyoZ5u%2FStub%20Roller%20-%20Step%203.svg?alt=media&amp;token=9872eff5-f4ad-43d0-a5fe-3dfd6a028867" alt="" width="563"><figcaption></figcaption></figure>

## Step 4

Thread the bolt through your desired mounting surface and into the Stub Shaft. Use the Stub Shaft Wrench to hold the Stub Shaft in place while tightening the bolt.&#x20;

{% hint style="warning" %}
The table below will show what bolt to use for each Stub Shaft length. Lengths are determined using a 1/4" thick mounting surface, anything thicker than this will need a longer bolt.
{% endhint %}

| 1-3/4"L Stub Shaft | 2-1/4"L Stub Shaft    | 2-3/4"L Stub Shaft |
| ------------------ | --------------------- | ------------------ |
| #10-32 x 2"L Bolt  | #10-32 x 2-1/2"L Bolt | #10-32 x 3"L Bolt  |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.wcproducts.com/welcome/system-and-structure/wcp-stub-rollers/assembly-instructions/getting-started.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
