4. Setup and Installation
Installation of the GDOOL PX9200-18 shock absorbers typically involves replacing existing units. Basic tools such as a small screwdriver or hex wrench may be required.
- Preparation: Ensure your RC vehicle is powered off and stable. Remove the wheels if necessary to access the shock absorbers.
- Removal of Old Shocks: Locate the upper and lower mounting points of the existing shock absorber. Carefully remove the screws or pins securing the shock to the chassis and suspension arm. Retain any washers or bushings if they are reusable.
- Shock Oil Filling (Important): It has been observed that these shock absorbers may arrive with insufficient or no shock oil. For optimal performance, it is recommended to fill each shock with appropriate RC shock oil (e.g., 25W to 50W, depending on desired damping characteristics).
- Carefully unscrew the top cap of the shock absorber.
- Slowly fill the shock body with shock oil, leaving a small air gap at the top.
- Gently compress and extend the shock shaft several times to remove any trapped air bubbles.
- Top off the oil if necessary and then carefully re-install the top cap, ensuring a tight seal to prevent leaks.
- Installation of New Shocks: Align the new GDOOL PX9200-18 shock absorber with the upper and lower mounting points. Secure it using the provided screws/bushings or the original hardware if compatible. Ensure the screws are tightened securely but do not overtighten.
- Ride Height Adjustment: The ride height can be adjusted by rotating the threaded collar on the shock body. This can typically be done even after installation. Adjust all four shocks evenly for balanced suspension.
- Final Check: Once all shocks are installed, gently compress the suspension on all corners to ensure smooth movement and proper damping.
5. Maintenance
Regular maintenance will extend the lifespan and performance of your shock absorbers.
- Inspection: Periodically inspect the shock absorbers for any signs of damage, such as bent shafts, cracked plastic components, or oil leaks.
- Cleaning: After use, especially in dirty or dusty conditions, clean the exterior of the shocks to prevent debris from entering the seals. Use a soft brush and mild cleaner if necessary.
- Oil Check and Refill: Over time, shock oil can degrade or leak. Check the oil level and condition regularly. If damping performance decreases or leaks are observed, replace or refill the shock oil as described in the "Setup and Installation" section.
- Seal Replacement: If persistent leaks occur after refilling oil, the internal O-rings or seals may need replacement. This typically requires disassembling the shock.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Shocks are leaking oil. | Insufficiently tightened cap, damaged O-rings/seals, or manufacturing defect. | Ensure top caps are securely tightened. If leaks persist, disassemble, inspect, and replace O-rings/seals. Refill with appropriate shock oil. |
| Poor damping performance (too bouncy or too stiff). | Incorrect shock oil weight, low oil level, or air trapped inside. | Verify shock oil level and type. Refill or replace oil, ensuring all air bubbles are removed during the filling process. Adjust ride height if necessary. |
| Shock shaft is bent or damaged. | Impact from aggressive driving or collision. | Replace the damaged shock absorber. |
