4. Setup

1. Secure your bicycle: Mount your bicycle securely in a repair stand to ensure stability during the removal process.
2. Identify bottom bracket type: Confirm that your bicycle's press-fit bottom bracket uses 22-24mm spindles and is compatible with the YC-1858-22N tool.

5. Operating Instructions

Follow these steps to safely remove press-fit bottom bracket cups:

1. Insert the tool: Carefully insert the BIKE HAND YC-1858-22N tool through the bottom bracket shell from the side opposite the cup you intend to remove.

2. Engage the cup: Push the tool until its flared ends expand and securely snap behind the bearing cup. You should feel a distinct click or increased resistance, indicating that the tool is properly seated and gripping the cup.
3. Remove the cup: Using a rubber mallet or plastic-faced hammer, strike the head of the removal tool firmly and squarely. The impact will drive the bottom bracket cup out of the shell. Repeat strikes as necessary until the cup is fully dislodged.

4. Repeat for the second cup: If your bottom bracket has two separate cups, reposition the tool to remove the second cup, following the same procedure.

6. Maintenance

• Cleaning: After each use, clean the tool thoroughly to remove any grease, dirt, or debris. A clean cloth and a mild degreaser can be used.
• Storage: Store the tool in a dry environment to prevent rust and corrosion. Keep it away from excessive moisture and extreme temperatures.
• Inspection: Periodically inspect the flared ends of the tool for any signs of wear, bending, or damage. Replace the tool if significant damage is observed to ensure proper function and safety.

7. Troubleshooting

• Tool fingers bending: If the tool's flared ends (fingers) bend during use, it may indicate that the bottom bracket cups are extremely tight, seized, or that the tool was not fully engaged behind the cup. Ensure the tool is properly seated before striking. If significant bending occurs, the tool's effectiveness may be compromised, and replacement might be necessary.
• Difficulty removing cup: If a bottom bracket cup is difficult to remove, ensure the tool is correctly and fully engaged. Applying a penetrating oil to the interface between the cup and the frame may help loosen seized components. Use firm, controlled strikes with the mallet. Avoid excessive force that could damage the frame or the tool.
