Yes, light lubrication is recommended for the YIKONG YK4107 RC Car Parts 11T Driving Gear (Part No. 21035), but don’t apply too much. During installation or routine maintenance, apply a thin layer of gear grease to the gear teeth to help reduce friction and wear, allowing the drivetrain of your YIKONG YK4107 RC Car to operate more smoothly.
If you frequently drive your YIKONG YK4107 RC Car in sand, mud, or wet conditions, it’s a good idea to clean the gear first and then reapply a small amount of grease. Keep in mind that excessive grease can attract dirt and debris, which may affect gear performance, so a light coating is all that’s needed.
In my experience, regular maintenance makes a big difference. After every run with the YIKONG YK4107 RC Car, especially in sand or mud, I clean the area around the 34T Driven Gear (Part No. 21033) to keep dirt and debris from getting between the gear teeth and causing unnecessary wear.
I also apply a small amount of grease to the 34T Driven Gear from time to time. It doesn’t need much—just enough to keep the gears meshing smoothly. When driving the YIKONG YK4107 RC Car, I also try to avoid frequent full-throttle launches or long periods of heavy-load crawling, since those put extra stress on the gear. With these simple maintenance habits, the 34T Driven Gear (Part No. 21033) should last much longer and continue to perform reliably.
Replacing the C Hub Set (Part No. 21002) on the YIKONG YK4107 RC Car is fairly straightforward. First, remove the original C hubs from both sides of the front axle, then take off the steering knuckles, bearings, and related hardware. Install the bearings and other components into the new C Hub Set, and reassemble everything using the original screws and factory mounting positions. Make sure the left and right C hubs are installed on the correct sides to ensure proper steering and suspension movement. After installation, check that the steering moves freely, all screws are securely tightened, and perform a low-speed test to confirm everything is working correctly.
If the gears feel too tight after installing the Rear Portal Housing on your YIKONG YK4107 RC Car, don’t assume there’s a problem with the parts right away. In many cases, it’s caused by the installation. Check that the gears are installed in the correct positions, the bearings are fully seated, the grease hasn’t been applied excessively, and the screws are tightened evenly. If one side is overtightened, it may slightly deform the portal housing and cause the gears to bind. Rechecking and adjusting the installation will usually restore smooth gear operation.
Where can I buy a metal rear portal housing upgrade for the YIKONG YK4107 RC Car?
If your YIKONG YK4083/V3 RC Car Wheels (Part No. 14150) have factory-glued tires, the easiest way to separate the tire from the wheel is by heating the glue. This method is generally safe for the wheel when done carefully.
You’ll need a heat gun (a hair dryer can also work, but it takes longer) and a cloth or heat-resistant gloves. Hold the heat gun about 5–8 cm (2–3 finger widths) away from the glued edge of the wheel and heat it evenly for 3–5 minutes. Once the glue begins to soften, gently lift the edge of the tire and slowly work it loose while continuing to apply heat. Avoid using excessive force.
If some sections are still firmly attached, simply heat those areas a little longer and continue separating the tire gradually. After one side is removed, repeat the same process on the other side.
Once the tire is completely separated, allow it to cool slightly before removing the foam insert. In most cases, the glue is only applied around the outer bead of the wheel, while the center groove is not glued. By heating the bead evenly and taking your time, you can usually remove the tire without damaging the YIKONG YK4083/V3 RC Car Wheels (Part No. 14150).
Note: This method will usually preserve the tire and foam insert, but the wheel itself will most likely be damaged beyond reuse. If you already plan to replace the wheel and only want to keep the tire and foam insert, this is a suitable method.
In general, they don’t require oiling, but light lubrication can be applied if needed. When installing the Rear Wheel Axles (Part No. 13150) of the YIKONG YK4083/V3 RC Car, you can apply a thin layer of grease on the areas that contact the bearings or drivetrain components. This helps reduce friction and wear, making the drivetrain run more smoothly.
I’d start by checking the simple things first. Make sure the connector on the YIKONG 17g Shift Servo (Part No. 13119) is plugged in securely and that the wiring isn’t loose. Then check whether the shift linkage is stuck with dirt or mud, or if the shift fork has moved out of position. If everything looks fine, see if the battery voltage is too low or if the servo gears are worn out. If the servo doesn’t respond at all, there’s a good chance the YIKONG 17g Shift Servo (Part No. 13119) itself has failed and needs to be replaced. In most cases, checking these items in order will help you find the problem quickly.
The YIKONG YK4103 RC Car Parts Shims (no.13069) are thin spacers used to adjust the clearance between components. They are typically installed in locations such as gears and bearings where axial play needs to be adjusted. The shim size is 8 × 5.1 × 0.2 mm.
The main purpose of the YIKONG YK4103 RC Car Shims (13069) is to reduce unwanted clearance, improve gear mesh, prevent side-to-side movement of components, and reduce abnormal wear and noise. This helps the drivetrain of your YIKONG YK4103 RC Car run more smoothly. If you notice excessive gear backlash or obvious play, you can add shims as needed to achieve a better fit. However, avoid using too many shims, as excessive preload may affect the normal operation of the parts.
No. The YIKONG YK4102 RC Car Parts Aluminum Hex Nuts 13057 only need to be tightened until they are secure. Overtightening is not recommended, as it may damage the threads or make the nuts difficult to remove later. Once installed, check that the wheel spins freely without excessive play. After driving your YIKONG YK4102 RC Car for a while, it’s also a good idea to recheck the hex nuts to make sure they remain tight.
Yes. Replacing the Bodyshell Cage 13024 on the YIKONG YK4101 RC Car is a straightforward job. Simply remove the original bodyshell cage and its mounting screws, position the new Bodyshell Cage 13024 over the factory mounting points, and tighten the screws. After installation, check that the cage is securely fastened and does not interfere with other body components.
