The RockShox Recon RL Gold [paid link] is a highly regarded suspension fork known for its smooth performance and adjustable features. To maintain its optimal functionality and extend its lifespan, performing regular oil changes is crucial. In this guide, we will walk you through the process of changing the suspension fork oil in the Recon RL Gold [paid link], ensuring that you get the best performance from your bike.
Tools Required
Before starting, make sure you have the following tools and supplies ready:
- 5mm Allen wrench [paid link]
- 10mm Allen wrench [paid link]
- Suspension fluid (appropriate weight for your fork)
- Clean rags or paper towels
- A fork seal driver
- T20 Torx wrench [paid link]
- Oil drain pan or container
- Grease (for lubrication)
- Large syringe (for oil refilling)
- Torque wrench [paid link]
- Bucket for cleaning parts
Preparation
1. Remove the Fork from the Bike
- Use a 5mm Allen wrench to detach the fork from the frame.
- Remove any front wheel and brake calipers if necessary.
2. Clean the Fork
Before proceeding with the oil change, it’s important to clean the fork to avoid dirt and debris from entering the internals during the disassembly. Use a clean rag to wipe down the stanchions, crown, and lower legs.
3. Set Up a Work Area
Place the fork on a clean, flat surface. Ensure you have ample space to work and lay out the necessary tools. A workbench or sturdy table will help with the stability of the fork during the disassembly.
Disassembly
1. Remove the Air Spring
The air spring is the first component to be removed to allow access to the fork’s internals.
- Loosen the air valve using the 5mm Allen wrench to release the air pressure.
- Remove the top cap using a 10mm Allen wrench. This should reveal the air spring assembly.
- Carefully pull the air spring out of the lower leg.
2. Remove the Damper Cartridge
The Recon RL Gold features a motion control damper, which needs to be removed to drain and replace the oil.
- Unscrew the rebound knob from the lower leg using the T20 Torx wrench [paid link].
- Remove the damper by loosening the bolts at the bottom of the fork using a 10mm Allen wrench. Once loosened, carefully pull out the damper cartridge.
3. Drain the Old Oil
Place the fork upside down in the oil drain pan or container to allow the old suspension oil to fully drain out. Allow it to sit for several minutes to ensure complete oil drainage.
4. Remove the Fork Seals
Using a fork seal driver, carefully pry out the seals at the bottom of the fork. Clean the seals thoroughly before reinstallation to ensure they are free of dirt or contaminants.
Cleaning and Inspection
1. Clean the Internals
Use a clean rag to wipe down all internal components, including the damper, stanchions, and the inside of the lowers. Inspect the parts for any wear or damage, particularly the damper and seals. If you notice any issues, consider replacing the worn parts before proceeding.
2. Inspect the Seals
Before reinstalling the seals, inspect them for any signs of damage or excessive wear. If the seals appear damaged, replace them with new ones to maintain the performance of the fork.
Reassembly
1. Install the New Oil
- Use a large syringe to carefully inject the recommended amount of suspension oil into the lower legs. Refer to the RockShox manual for the exact volume of oil required for your specific fork model.
- Ensure the oil is evenly distributed within the lower legs to avoid air pockets.
2. Reinstall the Damper Cartridge
- Slide the damper cartridge back into the fork, making sure it fits securely. Tighten the bolts at the bottom of the fork with a 10mm Allen wrench, ensuring they are torqued to the manufacturer’s specifications.
- Reinstall the rebound knob and secure it tightly using the T20 Torx wrench.
3. Reinstall the Air Spring
- Carefully slide the air spring back into the lower leg.
- Secure the air spring by tightening the top cap with the 10mm Allen wrench.
- Re-inflate the air spring to the desired pressure.
4. Replace the Fork Seals
Install the cleaned fork seals back into the lower legs using the fork seal driver. Be careful to seat them properly to prevent oil leaks.
Final Checks
1. Reinstall the Fork onto the Bike
- Reattach the fork to the bike frame using the 5mm Allen wrench. Ensure the fork is securely fastened.
- If you removed the brake calipers or front wheel, reinstall them at this stage.
2. Perform a Quick Test
With the fork reinstalled, perform a quick test by pushing down on the handlebars. Ensure that the fork is moving smoothly and that there is no unusual resistance or noise. If the fork feels too soft or too stiff, you may need to adjust the air pressure or oil level.
3. Check for Leaks
After reassembly, check the lower legs and air spring area for any signs of oil leaks. If you notice any leaks, tighten the relevant bolts and seals. If the issue persists, you may need to recheck the seal installation or consider replacing worn seals.
Troubleshooting Common Oil Change Issues
1. Fork Still Feels Too Soft or Too Stiff
If your fork doesn’t feel right after the oil change, there may be an issue with the air pressure or oil level. Double-check the air pressure settings according to your rider weight and riding style. If the issue persists, you may need to drain and refill the oil to ensure proper volume.
2. Oil Leaks
Oil leakage after an oil change usually points to improperly installed seals or loose bolts. Make sure the seals are installed correctly and that the bolts are torqued to the specified value. If the problem continues, replacing worn seals may resolve the issue.
Conclusion
Performing an oil change on your RockShox Recon RL Gold suspension fork is a straightforward task when following the proper steps. Regular maintenance, including oil changes, will help keep your fork running smoothly and enhance your overall riding experience. By understanding the process of disassembly, cleaning, and reassembly, you ensure that your fork continues to provide exceptional performance for years to come.
