How to Install the Tonnerrey T8 Front Axle Washer Correctly
Where does the T8 front axle washer go?
The front axle washer must be positioned correctly between the front wheel axle hardware and the fork dropout area. The exact washer and axle arrangement differs between the T8 Dual Motor and T8 Single Motor versions, so always follow the instructions for your specific model.
Why Correct Washer Installation Matters
The front axle washer is part of the hardware that helps position and secure the front wheel assembly. Correct placement helps the axle sit properly at the fork dropout and supports stable wheel installation.
Incorrect placement, missing hardware or an improperly seated axle can affect front wheel alignment and may also interfere with proper brake rotor positioning.
Do not ride the bike if the front axle, washer or axle nut is loose, missing or incorrectly positioned. If you are unsure about the installation, stop and contact Tonnerrey support or a qualified bicycle technician before riding.
Identify Your T8 Version First
The T8 Dual Motor and T8 Single Motor use different front axle configurations. Do not assume the washer arrangement from one version applies to the other.
T8 Dual Motor
The Dual Motor version uses a powered front hub and a dedicated axle retaining washer / plate at the front fork dropout.
T8 Single Motor
The Single Motor version uses a conventional front axle assembly with washers and nuts positioned on both sides of the wheel.
Front Axle Washer Installation
Use the following reference images to identify the Dual Motor axle retaining washer and confirm its installed position.
Identify the Axle Washer
Before installing the front wheel, identify the black axle retaining washer / plate shown in the image. Confirm that you have the washer and axle nut hardware ready before positioning the wheel in the fork.
Confirm the Installed Position
Once the wheel is seated in the fork dropout, position the retaining washer so it sits flat and securely around the axle area as shown. Install the axle nut over the washer and secure the assembly.
Because the T8 Dual Motor uses a powered front hub, make sure the front axle is fully seated and the retaining hardware is positioned correctly before tightening the axle nut.
Front Axle Washer Installation
The Single Motor front wheel uses an axle with washers and nuts on both sides. Use the reference photos below to check the order and final installed position.
Check the Axle Hardware Order
Before installing the wheel, verify that the washers and nuts are present on both sides of the axle. Keep the hardware in the correct order while preparing to install the wheel.
Confirm the Final Position
After placing the wheel into the fork dropouts, position the washers and nuts on both sides. Make sure the washers sit flat and the wheel axle is fully seated before tightening.
Front Wheel Installation Checklist
Regardless of version, the front wheel should be installed in a controlled sequence so that the axle, washers, brake rotor and axle nuts are all positioned correctly.
Place the Front Wheel Into the Fork Dropouts
Carefully guide the axle into the fork dropouts and make sure the wheel sits fully and evenly in position.
Guide the Brake Rotor Into the Caliper
As the wheel is installed, make sure the brake rotor enters the brake caliper correctly rather than sitting outside or against the caliper body.
Position the Correct Washer Hardware
Install the washer or retaining plate in the correct position for your T8 version. The Dual Motor and Single Motor layouts are not identical.
Install and Pre-Tighten the Axle Nuts
Thread the axle nuts into position and pre-tighten them while checking that the wheel remains centered and fully seated.
Confirm Wheel and Rotor Alignment
Before final tightening, visually confirm that the wheel is centered and the brake rotor runs through the caliper correctly.
Secure the Axle Hardware
Fully secure the axle nuts according to the appropriate Tonnerrey installation instructions. Both sides should be secure before the bike is ridden.
Install Protective Nut Caps if Supplied
After the axle hardware is secured, reinstall any protective axle nut caps included with your T8.
Common Front Axle Washer Installation Mistakes
Missing the Washer
Do not install or ride the bike with required axle washer hardware missing.
Using the Wrong Layout
Do not copy the Single Motor washer arrangement onto the Dual Motor version, or vice versa.
Washer Not Sitting Flat
Make sure the washer or retaining plate is properly seated rather than angled or caught on the fork dropout.
Axle Not Fully Seated
The axle should sit fully inside the fork dropout before the hardware is finally tightened.
Brake Rotor Misalignment
Confirm that the rotor is correctly positioned inside the brake caliper during wheel installation.
Riding Before Rechecking
Always perform a final wheel, axle and brake check before the first ride after installation.
Post-Installation Safety Check
Take a few minutes to inspect the front wheel assembly before putting weight on the bike or beginning a ride.
Watch the Correct Installation for Your T8
Use the video that matches your bike version before completing the front wheel installation.

If the Washer Position Doesn't Look Right, Stop Before Riding
If the front axle hardware does not match the examples above, the wheel does not sit correctly in the fork, or you are unsure whether the washer is installed properly, contact Tonnerrey support before riding the bike.
