FAQs
What type of DT Swiss hubs is this tool compatible with?
This tool is exclusively for DT Swiss Ratchet drive rear hubs, such as the 240s and 350 models.
Can I use this tool on DT Swiss pawl drive hubs?
No, this tool is not compatible with pawl drive hubs. A different tool (HBDT5266) is required for those systems.
How should I secure the tool for use?
The tool is designed to be fitted into a vice for stability. Ensure the vice does not crush the tool.
What happens if I overtighten the vice on the tool?
Overtightening the vice can damage the tool, potentially leading to cracks or deformation. Grip it firmly but avoid excessive pressure.
Can this tool be used for installing bearings as well as removing them?
Yes, the tool is designed to assist with both the removal and replacement of the inner bearings located behind the ring nut.
Where can I find the model number of my DT Swiss hub?
The model number is usually printed on the hub shell itself or can be found in the original documentation for your wheelset or bicycle.
Troubleshooting
Tool does not fit the ring nut.
Verify that your hub is a DT Swiss Ratchet drive system. This tool is not compatible with pawl drive hubs or other brands. Ensure you are attempting to engage the correct part of the hub's internal mechanism.
Ring nut is extremely difficult to remove.
Ensure the tool is securely and squarely engaged with the ring nut. Confirm you are using the tool in a stable setup, such as a vice. Apply steady, consistent force. If the nut is cross-threaded or seized, professional assistance may be required.
Tool appears to be damaged after use.
Inspect the tool for cracks or deformation, especially if excessive force was applied or if the vice was overtightened. Discontinue use if damage is evident to prevent further damage to the hub or potential injury.

Setup, Compatibility & Care
Compatibility: This tool is strictly for DT Swiss Ratchet drive rear hubs. This includes common series like the 240s, 350, and bearings found in many DT Swiss complete wheelsets that utilize the Ratchet system. It is NOT compatible with DT Swiss pawl drive systems (for which the HBDT5266 tool is needed) or hubs from other manufacturers.
Setup: For workshop use, the tool is designed to be inserted into a vice. Ensure the vice jaws grip the tool firmly but do not overtighten, as excessive pressure can damage the tool itself. Once secured, align it with the ring nut on the DT Swiss hub for bearing removal or installation.
Care: After use, clean the tool with a dry or slightly damp cloth to remove grease and debris. Store it in a dry place, away from corrosive elements. Regularly inspect the tool for any signs of wear or damage, particularly around the gripping surfaces.
