This guide will walk you through the necessary steps to change the oil in your Float X Factory [paid link] rear shock, ensuring you get the most out of your ride.
Tools Required
- 8mm and 10mm socket wrenches
- Torque wrench [paid link]
- 3mm and 4mm hex keys [paid link]
- Oil bath or clean container for draining
- Suspension fluid (Fox Float Fluid or equivalent)
- Clean rag or towel
- Isopropyl alcohol (for cleaning)
- Silicone grease
- Fox Float X Factory oil change kit (if available)
- Shock pump (optional for re-pressurization)
Disassembly of the Float X Factory Shock
Before you begin, it’s important to remove the shock from your bike to ensure a clean, efficient oil change. Here’s how to do it:
- Remove the Shock from the Bike
Use a 5mm hex key [paid link] to remove the bolts securing the shock to the frame. Keep track of the hardware so you can reassemble it later. - Set the Shock on a Clean Surface
Place the shock on a clean, flat surface to prevent dirt and grime from contaminating the internal components.
Draining the Old Oil
With the shock removed, it’s time to drain the old oil and prepare for the oil change.
- Remove the Air Sleeve
Using a 10mm socket wrench, remove the air sleeve from the shock body. This will give you access to the oil reservoir. Carefully pull off the sleeve, and be mindful not to damage any seals during removal. - Drain the Old Oil
After removing the air sleeve, pour the old oil into a container to discard it properly. Gently tap the shock on the side to help ensure all the oil is drained from the body. - Clean the Shock Body
Use a clean rag or towel to wipe down the shock body. Make sure to remove any old oil residue or dirt. You can also use isopropyl alcohol to clean areas with heavier residue.
Cleaning the Internals
Before you add fresh oil, it’s important to ensure the shock internals are completely clean.
- Clean the Shaft and Piston
Use a clean cloth and isopropyl alcohol to wipe down the piston and shaft. This ensures there are no contaminants inside the shock body that could affect the new oil’s performance. - Inspect the Seal and O-Rings
Carefully check the seals and O-rings for wear and tear. Replace any damaged or worn seals with new ones from your Float X Factory shock kit. Proper sealing is crucial for preventing air and oil leaks.
Adding Fresh Oil
Now that the shock is clean, it’s time to add fresh oil.
- Fill with New Oil
Use the appropriate amount of Fox Float Fluid or equivalent suspension fluid, as recommended by the manufacturer. Pour the oil into the shock body slowly, making sure it fills all internal cavities. Be cautious not to overfill. - Lubricate the Shaft with Silicone Grease
Apply a small amount of silicone grease to the shaft to help ensure smooth operation and prevent any future wear. - Reassemble the Air Sleeve
Once the shock is filled with oil, carefully reinstall the air sleeve back onto the shock body. Make sure the seals are seated properly and the sleeve is securely fastened.
Reinstalling the Shock
After the oil change is complete, the next step is to reinstall the shock onto your bike.
- Reattach the Shock to the Bike
Carefully align the shock with the frame mounts and reattach it using the hardware you removed earlier. Use a torque wrench [paid link] to tighten the bolts to the manufacturer’s specified torque setting. - Check for Leaks
Before fully tightening the bolts, it’s a good idea to perform a quick visual check for leaks. Gently compress the shock to see if any oil leaks from the air sleeve or seals. - Repressurize the Shock
Use a shock pump to add air pressure to the air chamber of the shock. Set the pressure according to your weight and riding preferences. Be sure to check for correct pressure once it’s installed on the bike.
Testing and Final Adjustments
Once everything is reassembled, it’s time to test the shock and make any necessary adjustments.
- Test the Shock’s Performance
Perform a few test compressions to check the shock’s performance. Ensure that it rebounds properly and that the suspension feels smooth and consistent. - Adjust the Settings
Fine-tune the shock’s rebound and compression settings to your riding style and terrain preferences. Start with the factory settings and make gradual adjustments as needed.
Troubleshooting Common Set-Up Issues
While performing the oil change on your Fox Float X Factory shock, you may encounter some common issues. Here’s how to troubleshoot:
- Leakage After Reassembly
If you notice oil leakage after reassembling the shock, ensure that the seals and O-rings are properly installed and undamaged. A small amount of silicone grease can help create a better seal. - Poor Rebound or Compression
If the shock doesn’t rebound properly or feels sluggish, double-check that the oil level is correct and that no air bubbles are trapped in the shock body. Air bubbles can affect the shock’s performance. - Excessive Sag
If the shock feels too soft and the sag is too much after the oil change, you may need to adjust the air pressure. A shock pump will help you find the correct pressure.
Conclusion
Changing the oil in your Fox Float X Factory rear shock is an essential maintenance task that will help keep your bike’s suspension running smoothly and efficiently. By following these detailed steps, you can perform the oil change with confidence, ensuring your shock performs at its best for longer. Regular maintenance of your shock will also reduce the chances of major issues developing down the line.
