R/C Car/Truck Shock Maintenence

Intro: R/C Car/Truck Shock Maintenence

In this instructable i will show you how to do routine maintenance on your R/C car or trucks shock

The Stuff You Will Need:
-Shock oil ( I used 30wt)
-R/C Shocks (No duhhh =) )
-Paper Towels
-Pliers <-- hope i spelled it wright

Step 1: The Fun Begins

Remove the spring retainer from the piston. Then remove the spring from the shock.

Step 2:

Remove the clamp at the top and any other peaces left on the body of the shock. (see pic 1)

Attach a peace of tissue paper to your pliers(see pic 3).

After grabbing the piston with the pliers remove the bottom connector.

When you have removed that remove the dampener.

Look at the fourth photo for more detail on what to remove.

Step 3: Empty the Sucker Out

Empty out the shock fluid by removing the top cap of the shock.

Then remove the piston and wipe it clean.

Step 4: All Apart

This is all the peaces you should see when you are done taking the shock apart.

Step 5:

Put the clip on then fallowed by the retainer.

Step 6:

Put the piston back in

Step 7:

Put the dampener back on then the bottom connector.

Step 8:

Expand the piston out then fill the shock up with the shock fluid. Dont fill it to the rim because as the piston moves up the piston rod will displace some of the oil there for it will over flow.

Step 9:

Slowly move the piston up and down to eliminate bubbles. Repeat this step as many times as needed. There can be some minor spillage when you are preforming this step.

Step 10: The Last Step

Close the cap, put the spring back on and then put the lower spring retainer back on.

You have successfully re built your car or trucks shocks .

!!!!!Congratulations !!!!!!

    One question shouldn't there be a little rubber seal that fits onto the shock before the top cap is screwed on? Also you always want the oil to overflow a little when you put the cap back on. This is to ensure that there is no pocket of air in the shock.

    Actually it is generally a good idea to leave about 1/5 of the shock empty. if you overfill the shock it can damage the piston and the o ring. You can tell if you've overfilled the shock if you compress it without a spring on it rebounds more than 1/4 of the way.

    Hi guys,

    I'm a forigner here as in that I dont run 4x4's and so on. I'm actually working on making a custom set of landing gear for a high end 8 motor drone. The payload is pretty expencive and the all up weight is around 8kg. Sorry I dont know what that is in pounds.

    Anyway in my quest to set this up I decided the best way to dampen the harsh effect of the landing jolt thats experienced by all to often hard landings was to employ a landing gear that used a shock absorbing arm to take the jolt, basically soften that initial contact. Ive chosen a metal shocky thats quite big but Ive also discovered that they dont come with any oil. Which brings me to you guru's. I need to know what oil to use. Obviously shocky oil..... der..... but the grade I have no idea about. I dont want it to the shocky to be really hard, damn, its hard to explain. So Im turning to you guys to share your knowledge.

    Many thanks

    Brett

    The Higher you expect to be falling from, the lower the weight you are going to want to use. For example, on an RC Car, 35 weight is better for jumping, whereas 60 weight is better for Street racing. Basically the harder the fall, the lower the weight.

    Shocks and springs are part of the suspension in RC vehicles. Oil-filled shocks give RC vehicles more stability over rough terrain. Without the oil the shocks compress and rebound too quickly and fail to absorb or dampen the bumps in the road. When you feel that your shock absorbers aren't performing properly you can check the fluid level and add more oil to the shocks.

    Nice clear steps - how often does this need to be done?

    You did spell "pliers" correctly, but you've used the wrong "peace" (piece)

    Thanks for the reply, I guess "tanks" means "of fuel". Are these just cheap, or is there something in the design that they are supposed to be serviced regularly? L

    Sometimes dirt gets in the shock that can cause the oil to leak out. By changing the shock oil you can get rid of the dirt and prolong your shocks life
