4. Installation
Replacing the name plate and fixing screw is a straightforward process. Ensure you have the correct part (Left or Right) for your shifter.
Tools Required:
- Small Phillips head screwdriver
Procedure:
- Identify the correct part: Verify if you need the Left (Y0F498010) or Right (Y0F398020) name plate. The part number is usually printed on the packaging.
- Locate the existing screw: The name plate is typically secured by a single small screw on the side of the shifter body.
- Remove the old screw: Carefully use a small Phillips head screwdriver to unscrew and remove the existing fixing screw. Keep the screw safe if you intend to reuse it, though a new one is provided with the name plate.
- Remove the old name plate: Gently lift and remove the old name plate from the shifter body.
- Position the new name plate: Align the new name plate with the corresponding slot on the shifter body. Ensure it sits flush and correctly covers the internal components.
- Insert and tighten the new screw: Place the new fixing screw into the designated hole. Using the Phillips head screwdriver, carefully tighten the screw until it is snug. Do not overtighten, as this can strip the threads or damage the plastic name plate.
- Verify installation: Check that the name plate is securely in place and does not wobble.
5. Maintenance
Proper maintenance ensures the longevity and performance of your shifter components.
- Regular Cleaning: Periodically wipe down the name plate and surrounding shifter area with a clean, damp cloth to remove dirt and grime. Avoid harsh chemicals that may damage the plastic.
- Check Screw Tightness: Occasionally check the fixing screw for tightness. If it feels loose, gently tighten it with a Phillips head screwdriver. Do not overtighten.
- Inspect for Damage: Inspect the name plate for any cracks, chips, or excessive wear. If damage is present, consider replacing the part to prevent further issues or exposure of internal components.
6. Troubleshooting
This section addresses common questions and issues related to the name plate and fixing screw.
Common Issues & Solutions:
- Name plate is loose or rattling:
Ensure the fixing screw is properly tightened. If the screw is stripped, it may need to be replaced. If the name plate itself is damaged, it should be replaced. - Missing name plate or screw:
Replace with the appropriate original Shimano part (Y0F498010 for Left, Y0F398020 for Right).
Compatibility Questions:
- Is this compatible with ST-R7120 (12-speed 105)?
Yes, these name plates and screws are compatible with both ST-R7020 and ST-R7120 series shifters. - What model should I choose for Shimano 105 disc?
For the left shifter (ST-R7020-L / ST-R7120-L), choose part number Y0F498010. For the right shifter (ST-R7020-R / ST-R7120-R), choose part number Y0F398020. - Is this compatible with GRX RX-600?
These parts are specifically designed for Shimano 105 ST-R7020/R7120 series. While some users have reported successful installation on GRX, official compatibility is not guaranteed, and GRX RX-600 may use different specific parts. Always verify part numbers for your specific component.
7. User Tips
- Always use the correct size screwdriver: Using an ill-fitting screwdriver can strip the screw head, making removal difficult.
- Do not overtighten: The fixing screw is small, and overtightening can damage the plastic name plate or strip the threads in the shifter body. Tighten until snug, then stop.
- Keep spare parts: Given their small size, these parts can be easily lost during maintenance or in the event of a crash. Keeping a spare set can be beneficial.
- Check part numbers carefully: Ensure you order the correct left or right part number (Y0F498010 for Left, Y0F398020 for Right) to ensure proper fit.
