The DT Swiss XM 1700 SPLINE [paid link] wheels are a reliable and durable choice for mountain bikers who demand performance and quality. Over time, the bearings in the hub may wear out due to exposure to moisture, dirt, and the natural wear from constant use. Replacing the bearings is crucial to maintain smooth performance and ensure the longevity of the wheels. This guide provides a detailed, step-by-step process for replacing the bearings in your XM 1700 SPLINE [paid link] wheels.

Tools Required

  • Bearing press [paid link] or puller tool
  • Small hammer (for tapping bearings into place)
  • 2mm and 5mm Allen wrenches [paid link]
  • Grease (preferably waterproof)
  • Clean rag or paper towels
  • Small flathead screwdriver
  • 10mm wrench (for the locknut on the freehub)
  • Hub-specific bearing removal tool (if required)
  • Socket wrench (for disassembly of wheel components)
  • Bearing cleaning solution (optional)

Disassembling the XM 1700 SPLINE Wheel

Before you can replace the bearings in the DT Swiss XM 1700 SPLINE wheels, you’ll need to disassemble the wheel hub. This involves removing the freehub, axle, and any internal components.

  1. Remove the wheel from the bike: Begin by removing the wheel from your bike using your standard quick release or thru-axle system. Make sure your wheel is secured before starting the work.
  2. Remove the freehub body: Use a 10mm wrench to remove the locknut on the freehub. This will allow you to slide the freehub body off the hub. Be careful with this step, as there may be small pawls or springs inside that could fall out.
  3. Extract the axle: Depending on the hub configuration, you may need to use an Allen wrench [paid link] to remove the axle from the hub shell. For the XM 1700 SPLINE, this is typically done by loosening the 5mm Allen bolt at the non-drive side of the wheel.
  4. Clean the components: Use a rag to clean off any grease, dirt, or debris from the hub shell, axle, and freehub body. This ensures that no contaminants get into the bearings when you remove and replace them.

Removing the Old Bearings

The next step is to carefully remove the old bearings from the hub. You can either press them out or use a bearing puller tool, depending on what you have on hand.

  1. Identify the bearings to replace: The XM 1700 SPLINE wheels have a set of bearings located in the hub shell. Typically, there are two bearings on the non-drive side and one bearing on the drive side (depending on the wheel configuration). Identify which bearings need replacing.
  2. Press out the bearings: Using a bearing press [paid link] tool or a bearing puller, gently remove the old bearings from their respective positions. It’s important to apply even pressure to avoid damaging the hub shell. If you don’t have a bearing press, you can use a small hammer and a soft tool (like a dowel or small rod) to tap the bearings out from the opposite side.
  3. Clean the bearing seats: Once the bearings are removed, thoroughly clean the bearing seats with a rag to remove any dirt or grease that may have accumulated. A bearing cleaning solution can help remove grime that is hard to reach with just a rag.

Installing New Bearings

Once the old bearings are removed and the hub is clean, you can install the new bearings. Proper installation is key to ensure smooth rotation and longevity.

  1. Grease the bearing seats: Apply a thin layer of high-quality grease to the bearing seats in the hub shell. This will help the new bearings fit more smoothly and prevent corrosion from moisture. Be sure not to use excessive grease, as it may interfere with the bearing’s performance.
  2. Install the new bearings: Position the new bearings in the hub shell and use a bearing press to install them. Apply even pressure to push the bearings into place without damaging the hub. If you’re using a hammer, tap the bearings gently using a soft punch. Make sure they sit flush with the hub shell.
  3. Check the alignment: Once the bearings are in place, check their alignment by rotating the hub manually. The hub should spin smoothly without any grinding or resistance. If you notice any issues, recheck the bearings’ position and alignment.

Reassembling the Wheel

With the new bearings installed, you can begin reassembling the XM 1700 SPLINE wheel. It is crucial to ensure all components are reassembled correctly to guarantee optimal performance.

  1. Reinstall the axle: Place the axle back into the hub shell. Secure it in place by tightening the 5mm Allen bolt at the non-drive side of the hub.
  2. Reinstall the freehub body: Carefully slide the freehub body back onto the hub, ensuring that the pawls and springs are properly seated. Reinstall the locknut using a 10mm wrench to secure the freehub body in place.
  3. Check for smooth rotation: After reassembling the wheel, rotate the hub manually to ensure the freehub is engaging properly and that the wheel spins smoothly. If there is any resistance, you may need to adjust the installation or check the bearings again.

Final Check and Testing

After replacing the bearings and reassembling the wheel, it’s important to check everything one final time before reinstalling the wheel on your bike.

  1. Spin the wheel: Rotate the wheel by hand and listen for any unusual noises. A smooth, quiet spin is the sign of a successful bearing replacement.
  2. Install the wheel back on your bike: Reinstall the wheel on your bike, ensuring the axle is properly secured and the wheel is true. Double-check the brake pads to ensure they are aligned correctly with the rim or disc.
  3. Test the bike: Ride the bike to ensure everything is functioning correctly. Pay attention to the smoothness of the wheel’s rotation and listen for any signs of issues. If you notice anything off, inspect the wheel again or take it to a mechanic.

Conclusion

Replacing the bearings in your DT Swiss XM 1700 SPLINE wheels is a straightforward process that, when done properly, can restore the performance and longevity of your wheels. By following these step-by-step instructions, you can ensure that your bike remains in peak [paid link] condition and that your wheels continue to perform at their best. Whether you’re a seasoned mechanic or a beginner, replacing the bearings is an essential part of maintaining your wheel’s functionality and your overall cycling experience.
