• Shock Absorber Mid-Section Assembly

• O-ring seals

• Other internal components

Arrange the parts in order to simplify reassembly.

Step 3: Install the New Shock Absorber Cylinder

Transfer all internal components into the new YIKONG YK4061 RC Car Shock Absorber Cylinder (26032).

During assembly, make sure:

• The inside of the cylinder is clean.

• The O-rings are installed correctly.

• The shock shaft moves smoothly.

• All components are fully seated.

Proper assembly ensures reliable sealing and consistent damping performance.

Step 4: Refill with Shock Oil and Bleed the Air

Fill the cylinder with the appropriate amount of shock oil.

Then:

• Slowly cycle the shock shaft several times.

• Allow trapped air bubbles to escape.

• Top off the oil if necessary.

This process ensures smooth and consistent damping performance.

Step 5: Reassemble and Test

Reinstall the Upper Lid and then:

• Check for oil leaks.

• Verify smooth rebound action.

• Reinstall the shock absorber on your YIKONG YK4061 RC Car.

After installation, perform a low-speed test drive to confirm the suspension is operating correctly before returning to normal use.

Important Tips During Replacement

For the best results, remember to:

• Keep all components clean.

• Avoid scratching the inside of the cylinder.

• Replace worn O-rings whenever necessary.

• Do not overtighten the Upper Lid.

• Use the correct shock oil.

• Inspect the shock for oil leaks and proper rebound after installation.

Proper installation and maintenance will help maximize the service life of the suspension system on your YIKONG YK4061 RC Car.
