Tools Required
- 8mm and 10mm wrenches
- Torque wrench [paid link] (with proper settings)
- Suspension fluid (specific to Fox rear shocks)
- Fox Racing Shox seal kit
- Shock pump
- Small flathead screwdriver
- Pliers
- Clean, lint-free cloth
- Latex gloves
- Compressed air (optional)
- Suspension grease
Preparation and Disassembly
Step 1: Remove the Shock from the Bike
Before you begin the rebuild process, the shock must be removed from the bike. This involves loosening the mounting bolts at both ends of the shock using an 8mm or 10mm wrench, depending on the model of your bike. Ensure that the suspension is completely unloaded before removing the shock.
Step 2: Clean the Shock
Once the shock is removed, clean the exterior using a lint-free cloth. This is an important step as dirt and debris can compromise the shock’s performance and introduce contaminants during the rebuild process. Avoid using harsh chemicals; instead, use a mild soap solution and warm water to wipe down the shock.
Step 3: Release the Air Pressure
Before disassembling the shock, you must release the air pressure. Use a shock pump to carefully deflate the shock. Be sure to do this slowly and in a controlled manner to avoid any injury or damage to the shock components.
Disassembling the Shock
Step 4: Remove the Air Sleeve
The Float DPS shock features an air sleeve that needs to be removed in order to access the internal components. To do this, use a small flathead screwdriver or a dedicated seal driver to gently pry off the air sleeve from the main body of the shock. Take care not to damage the seals during this process.
Step 5: Remove the Damper Assembly
Once the air sleeve is off, you will need to remove the damper assembly. This can usually be done by loosening a retaining bolt at the top of the shock, allowing you to pull out the damper. Carefully inspect the damper for any signs of damage, excessive wear, or leakage. You may need to replace seals or the damper itself if it shows significant wear.
Step 6: Remove the Old Seals
The Fox Float DPS uses a variety of seals, which can wear out over time and cause the shock to lose performance. Using your fingers or pliers, remove all old seals, including the main shaft seal and any internal o-rings. It’s essential to replace all seals to ensure a proper rebuild and avoid future leaks.
Rebuilding the Shock
Step 7: Clean the Components
Before installing new seals and reassembling the shock, thoroughly clean all components. Use a clean, lint-free cloth to wipe down the damper, air sleeve, and other parts. You can also use compressed air to blow out any remaining debris, but be cautious not to damage any delicate components.
Step 8: Install New Seals
Using a Fox Racing Shox seal kit, replace all seals that were removed during the disassembly process. Carefully install each new seal, ensuring that it sits properly in its designated groove. Take care not to damage the seals as you install them, and make sure that they are properly lubricated with suspension grease to prevent wear and ensure smooth operation.
Step 9: Reassemble the Damper and Air Sleeve
Once the seals are installed, you can begin reassembling the shock. Start by reinstalling the damper assembly back into the shock body. Tighten the retaining bolt to the recommended torque specification to ensure that it is securely in place. Next, slide the air sleeve back onto the shock body, ensuring that the seals are properly seated.
Filling the Shock with Suspension Fluid
Step 10: Add Suspension Fluid
With the damper and air sleeve in place, it’s time to add suspension fluid. Refer to the manufacturer’s specifications for the correct type and amount of fluid required for your Fox Float DPS Performance rear shock. Add the fluid to the shock, ensuring that it is evenly distributed within the shock body. You can use a syringe or dropper to carefully measure and pour the fluid in.
Step 11: Reinstall the Shock Shaft
Before finishing the reassembly, carefully insert the shock shaft back into the shock body. Make sure the shock shaft is aligned properly and that the seals are seated correctly. Be cautious not to overfill the shock with fluid.
Reassembly and Testing
Step 12: Reattach the Air Sleeve and Shock Body
Once the fluid is added, reattach the air sleeve to the shock body and tighten it securely. Make sure all components are properly aligned, and no seals are pinched. After the air sleeve is in place, you can use a shock pump to add air back into the shock. Ensure that the air pressure is adjusted to the manufacturer’s recommended settings.
Step 13: Test the Shock
Before reinstalling the shock onto your bike, perform a quick function check. Compress the shock manually to ensure it moves smoothly and without any resistance. Listen for any unusual sounds, such as air bubbles or rough movement, which may indicate that further adjustments are needed.
Step 14: Reinstall the Shock onto the Bike
Once you are satisfied that the shock is functioning correctly, reinstall it onto the bike by reversing the steps from the removal process. Ensure that all bolts are tightened to the manufacturer’s torque specifications.
Troubleshooting Common Issues
Lack of Rebound or Compression Damping
If you notice that the shock’s rebound or compression damping is not functioning properly, it could be due to worn-out seals or improper fluid levels. Ensure that all seals are replaced and that the correct type and amount of suspension fluid are used. If the issue persists, inspect the damper assembly for internal damage.
Air Leaks
Air leaks can occur if the seals are not properly installed or if there is damage to the air sleeve. Carefully inspect all seals for damage and ensure they are installed correctly. If the issue continues, you may need to replace the air sleeve or damper.
Shock Not Holding Air Pressure
If the shock loses air pressure rapidly, this could indicate a problem with the air valve or the seals around the air sleeve. Perform a full inspection, including checking the air valve and seals for any signs of wear or damage.
Customization and Optimization
The Fox Float DPS Performance shock can be customized for a wide range of riding conditions. By adjusting the air pressure and tuning the rebound and compression settings, you can tailor the shock’s performance to suit your needs. It’s important to fine-tune these settings based on rider weight, terrain, and riding style.
For optimal performance, ensure that you regularly maintain the shock and replace seals as necessary. Customizing the air pressure to match your riding style can significantly improve your comfort and control on the trail.
Compatibility with Other Drivetrain Components
The Fox Float DPS Performance rear shock is compatible with a wide variety of mountain bike frames, as long as the frame design allows for the correct shock size and mounting configuration. When rebuilding the shock, it’s essential to check the shock’s compatibility with your frame, as an incorrect fit can lead to poor performance or even damage to the frame or shock.
Ensure that the shock’s travel, mount type, and overall dimensions are suitable for your bike’s specifications before rebuilding and reassembling.
Conclusion
Rebuilding your Fox Float DPS Performance rear shock at home is an achievable task with the right tools and knowledge. By following the steps outlined in this guide, you can restore the shock to its original performance and extend its lifespan. Regular maintenance and proper troubleshooting can help you avoid common issues and ensure that your shock continues to perform at its best, whether you’re racing down trails or cruising through rough terrain.
