4. Installation Guide
While specific instructions are not included with the product, the installation process for these bolt toppers is generally straightforward. It is recommended to use a few drops of silicone adhesive on the stem of the cap to ensure a secure fit and prevent them from dislodging due to vibration.
Recommended Installation Steps:
- Prepare the Surface: Ensure the bolt heads you intend to cover are clean and free of grease, dirt, or rust. Use a degreaser or alcohol wipe if necessary, and allow to dry completely.
- Select the Correct Cap: Identify the appropriate size and shape of the cap for each bolt head. The caps are designed to fit snugly over the bolt.
- Apply Silicone Adhesive: Apply a small amount (a few drops) of high-quality, clear silicone adhesive to the inside rim or stem of the bolt topper cap. Avoid excessive adhesive that could squeeze out and be visible.
- Position and Press: Carefully align the cap over the bolt head and press firmly until it seats securely. Twist slightly if needed to ensure an even distribution of the adhesive and a tight fit.
- Cure Time: Allow the silicone adhesive to cure fully according to the manufacturer's instructions (typically 24-48 hours) before operating the motorcycle. This will ensure maximum adhesion and prevent the caps from falling off.
- Inspect: After the curing period, gently check each cap to ensure it is firmly attached.
Note: This is an aftermarket custom item. Professional installation is recommended if you are unsure about the process.
5. Maintenance
These bolt toppers require minimal maintenance. Regular cleaning with a soft cloth and mild soap and water is sufficient to maintain their appearance. Avoid abrasive cleaners or harsh chemicals that could damage the plastic finish.
Periodically inspect the caps to ensure they remain securely attached. If a cap becomes loose, carefully remove it, clean both the cap and the bolt head, and reapply silicone adhesive as per the installation instructions.
6. Troubleshooting
Common Issues and Solutions:
- Caps do not fit:
- Ensure you have selected the correct size cap for the specific bolt head.
- Verify that your motorcycle model and year fall within the compatible fitment range (2007 and UP Harley Davidson FLT / FLH).
- Check for any obstructions or debris on the bolt head preventing a proper fit.
- Caps fall off:
- This is typically due to insufficient or improperly cured silicone adhesive. Reapply silicone adhesive following the installation steps carefully, ensuring adequate cure time.
- Ensure the bolt head was clean and dry before initial application.
- Excessive vibration from the motorcycle can also contribute; ensure a strong adhesive bond.
- Caps crack during installation:
- This indicates the cap is either too small for the bolt or excessive force was applied. Do not force the caps. Select a larger size if available, or confirm compatibility.
