Remove the Original 14mm Hexes
Before you can install the 17mm hex adapters, you need to remove the original 14mm hexes. To do this, you will need:
- A 5mm hex wrench
- A pair of pliers
- A small hammer
First, use the 5mm hex wrench to loosen the set screw on the hex adapter. Once the set screw is loose, you can use the pliers to remove the hex adapter from the wheel hub.
If the hex adapter is stuck, you can use a small hammer to tap it loose. Be careful not to hit the hex adapter too hard, as you could damage it.
Once the hex adapter is removed, you can repeat the process for the other three wheels.
| Step | Action |
|---|---|
| 1 | Loosen the set screw on the hex adapter using a 5mm hex wrench. |
| 2 | Use pliers to remove the hex adapter from the wheel hub. |
| 3 | If the hex adapter is stuck, use a small hammer to tap it loose. |
| 4 | Repeat the process for the other three wheels. |
Clean and Prepare the Axles
Before you begin the conversion process, it’s essential to thoroughly clean and prepare your axles. This will ensure that the new 17mm hex hubs fit securely and perform optimally.
Materials you’ll need:
| Item | Quantity |
|---|---|
| Soft-bristled brush | 1 |
| Cleaning solvent | 1 |

2. Next, you need to install the 17mm hex adapters. To do this, first apply a small amount of thread lock to the threads of the adapters. Then, screw the adapters into place by hand. Once the adapters are hand-tight, use a 5.5mm wrench to tighten them further.
3. Finally, you need to install the wheels onto the 17mm hex adapters. To do this, simply push the wheels onto the adapters until they snap into place.
| Part Name | Quantity | Size | Thread Pitch | Length |
|---|---|---|---|---|
| 17mm Hex Adapter | 4 | 17mm | M12 | 10mm |
| 5.5mm Screw | 8 | 5.5mm | M4 | 10mm |
| Thread Lock | 1 | Small bottle | N/A | N/A |
Secure the Adapters with Retaining Screws
The last and crucial step involves securing the adapters onto the wheel hex. This requires the use of the retaining screws that come with the adapter kit. These screws play a vital role in keeping the adapters firmly in place, ensuring a secure connection between the wheels and the axles.
To install the retaining screws, follow these steps:
- Place the wheel hex onto the adapter.
- Align the holes on the wheel hex and adapter with the corresponding holes on the retaining screws.
- Insert the retaining screws into the holes and tighten them using a screwdriver or hex key.
- Ensure that the screws are securely tightened to prevent the adapters from coming loose while driving.
- Repeat this process for all four wheels.
Here’s a table summarizing the key steps for securing the adapters with retaining screws:
| Step | Description |
|---|---|
| 1 | Place the wheel hex onto the adapter. |
| 2 | Align the holes on the wheel hex and adapter with the corresponding holes on the retaining screws. |
| 3 | Insert the retaining screws into the holes and tighten them using a screwdriver or hex key. |
| 4 | Ensure that the screws are securely tightened to prevent the adapters from coming loose while driving. |
