Rebuilding the Argyle DJ [paid link] fork can enhance its performance, extend its lifespan, and maintain its smooth feel for aggressive riding. In this guide, we’ll walk you through the process of rebuilding your Argyle DJ suspension fork, from disassembly to reassembly, and troubleshooting common issues.

Tools Required

  • 8mm hex wrench
  • 10mm hex wrench
  • 5mm hex wrench
  • 2.5mm hex wrench
  • 2mm hex wrench
  • Suspension fluid (specific to RockShox models)
  • Fork oil (specific to RockShox models)
  • Soft-bristled brush
  • Rags or cleaning towels
  • Plastic container for parts
  • Torque wrench [paid link]
  • C-clamp or vice
  • 32mm socket (if required for damper removal)

Disassembly of the Argyle DJ Suspension Fork

Before starting, make sure to clean the area where you’ll be working and gather all your tools. You’ll want to be in a clean and well-lit environment to ensure that parts are not lost or damaged during the process.

  1. Remove the Fork from the Bike
    • Start by removing the front wheel, brake caliper, and the fork from the bike. Use a 15mm wrench to remove the wheel axle and the quick release or thru-axle if applicable. For the brake caliper, use the appropriate wrench to remove it from the fork.
  2. Release the Air Pressure
    • Use a shock pump to release any air pressure from the fork. Be sure to do this step slowly and carefully to avoid any damage. Make sure the air is fully released before continuing.
  3. Remove the Lower Legs
    • Use an 8mm hex wrench to remove the screws that attach the lower legs to the fork stanchions. Once loosened, carefully slide the lower legs off. Keep the parts in a plastic container to avoid losing any washers or bolts.
  4. Remove the Damper and Spring
    • The damper and spring components will need to be removed next. Using a 10mm hex wrench, remove the damper from the fork. Afterward, use a 2mm or 2.5mm hex wrench to disconnect any retaining bolts for the spring and remove it from the fork. Take note of the order in which parts are assembled for reassembly later.
  5. Clean the Parts
    • Use a soft-bristled brush to clean any dirt and grime from the fork stanchions, damper, and springs. Wipe all parts with a clean rag and ensure no dirt remains on the components.

Rebuilding the Argyle DJ Suspension Fork

Now that the fork is disassembled, it’s time to rebuild it and put everything back together.

  1. Check All Components for Wear
    • Before reassembling, thoroughly check the seals, bushings, and any moving parts for wear. If any components appear damaged or excessively worn, consider replacing them with OEM parts from RockShox to maintain optimal performance.
  2. Apply New Suspension Fluid
    • Refill the fork with fresh suspension fluid, ensuring the correct type and amount as specified by the manufacturer. This is essential for maintaining smooth compression and rebound damping. Carefully pour fluid into the fork according to the instructions in the manual.
  3. Reassemble the Spring and Damper
    • Carefully insert the spring and damper back into their respective places in the fork. Make sure that the damper is properly aligned and the spring is seated securely. Reattach any bolts and retainers to ensure everything is firmly in place.
  4. Reinstall the Lower Legs
    • Slide the lower legs back onto the stanchions and align them properly. Use the 8mm hex wrench to tighten the screws that secure the lower legs to the stanchions. Be sure to tighten the screws evenly and to the correct torque specification to avoid any issues with the fork’s performance.
  5. Add Fork Oil to the Lowers
    • Pour the appropriate amount of fork oil into the lowers, as specified by RockShox. This oil helps lubricate the internals and maintain smooth movement. Be precise with the oil amount to avoid overfilling, which could lead to reduced performance or leaks.

Adjustments for Optimal Performance

Once you’ve reassembled your Argyle DJ suspension fork, it’s time to fine-tune it for optimal performance.

  1. Set Air Pressure
    • Using a shock pump, adjust the air pressure in the fork according to your weight and riding style. The recommended pressure can vary depending on rider preference, but a good starting point is usually between 90-120 psi for most riders.
  2. Rebound Adjustment
    • The Argyle DJ fork typically features a rebound adjustment knob. This knob controls how quickly the fork extends after compression. Set the rebound damping to a level that feels comfortable for your riding style. A slower rebound helps with stability, while a faster rebound offers quicker responsiveness.
  3. Compression Adjustment
    • Some versions of the Argyle DJ fork come with compression adjustment. This controls how the fork responds to larger impacts. Turn the compression dial to your desired setting for the type of riding you intend to do. Stiffening the compression is useful for aggressive riding, while a softer setting provides better sensitivity on smaller bumps.

Troubleshooting Common Set-Up Issues

Even after a proper rebuild, issues may still arise with the fork. Here are a few common problems and their potential solutions:

  1. Fork Feeling “Sticky” or “Grindy”
    • This may be due to insufficient lubrication or dirt buildup inside the fork. Open the fork again, clean all components, and reapply fresh suspension fluid and oil to ensure smooth operation.
  2. Leaking Air Pressure
    • If the fork is leaking air, check the seals and valves. A damaged seal may need to be replaced to restore air retention. Make sure that the valve is properly seated and there is no debris preventing it from sealing correctly.
  3. Uneven Suspension Travel
    • Uneven travel can be a result of incorrect oil levels or a problem with the damper or spring. Recheck the oil levels, and inspect the spring for any signs of damage or wear.

Compatibility with Other Drivetrain Components

The RockShox Argyle DJ suspension fork is designed to work seamlessly with a variety of drivetrain setups, especially in dirt jump and slopestyle bikes. However, always check compatibility between your fork’s axle, wheel, and your bike’s front dropout. The fork uses a standard 20mm axle, which is commonly used in dirt jump bikes. Be sure to check if your wheel and axle match the specifications of the Argyle DJ fork to ensure proper functionality.

Conclusion

Rebuilding and maintaining your RockShox Argyle DJ suspension fork is a crucial task to ensure its performance and longevity. By following the steps outlined in this guide, you’ll be able to disassemble, clean, and reassemble your fork with ease. Additionally, adjusting the settings and troubleshooting common issues will keep your fork in optimal condition for aggressive riding. Always be sure to use the correct parts and tools, and perform regular maintenance to extend the life of your suspension fork.
