Thanks man
Unfortunately it doesn't come with oils
I got the car and the remote
And a few spare parts.

i Not found in this time what oils are recommended for it.
Look in your manual. Or email the manufacturer. Or you should be able to find out with an internet search.
 
Don't put oil on the ring and pinion gears at the motor. Get that off there if you did. Those run dry, because they will collect dirt.

For diff housings, I use Mobil 1 synthetic grease. Diff fluid or grease in the differentials themselves, which varIes from RC to RC. Sealed diffs get fluid. Non-sealed diffs get grease. Diff fluid is a tuning thing, and nobody can really tell you what is best. It depends on your RC, your driving style, the terrain, mods done to the RC, etc. Same goes for shocks.

Start with the factory fluids, and adjust from there.
I just put WD 40 and silicone sprayon the engine gears to prevent rust.That's fine of course. I noticed that even silicone spray sticks sand to itI haven't put any oil on it yet.
 
I'll try to search, but I don't think there's any information about it online.
I checked the manufacturer's instructions on the page I received with the machine, and apart from spare parts and a general explanation,
there was nothing related to oil.
 
You can always look up other, more popular RC's similar to yours, same weight, same scale, same type, etc. Use their more thorough manuals to get you a baseline to test, and go from there.

How can you tell if they are sealed or not?
The only detailed information I was able to find about her Car is on this website.

I will also ask the manufacturer..
need to contact the manufacturer itself in China
But we will try. :]
 
Sealed diffs will have an o-ring or gasket that keep the diff sealed up tight. Others, like some ilof the Traxxas 2wd stuff are not sealed.

Note the blue gasket

This is a piece of garbage, and even the grease will leak out. Traxxas Slash diff.

ok thanks
I saw a material that is suitable for everything, including gears for bearings for diff sealed
in one package deal

Is it worth it?
With me using this so maybe I don't have to mess around with all kinds of different types of oils
 
I have never tried Cow RC stuff. I never could get used to the name 🤣

But yes, a lot of people like their stuff. To overpriced for me, as the stuff I buy works just fine.

It's like Green Slime o-ring and shock lube. It's like $10 for a tiny little tube of it. It is actually polymer 400 greade, which is a grease designed for use on farm tractors. They put a tiny bit in a bottle, jack the price up 3000%, and sell it to unsuspecting RC hobbyists. That being said, a $10 tube will last you forever, so no real biggie.

But $26 for an 8oz tub of grease? Yeah, I'm not that naive 😉
 
So maybe I should try
400 grade polymer
of using tractors

It may last a long time and do a good job?

Have you thought about trying?
 
I was able to open the wheels as it is a hex 17MM
When I rotate the area there is a noise of sand crunching
It is apparently from the area of the bearing.
The area is also dirty with sand

Am I allowed to spray water there and then wd40?
Or is silicone oil better?
Or do not spray water on the bearings and WD 40
together

I opened it and there is sand on the bearings
I cleaned as much as possible..
. Can I spray WD 40 on it?
 
Wipe bearings seal off, and if they feel a little "crunchy" you can try to clean and/or relube them, or just replace them. A lot of people don't want to waste their time with bearing maintenance. 🤔
 
You really shouldn't have grit in the bearings, being it is pretty new. But it happens. If there is grit in them, I wouldn't bother servicing them, because they're obviously crap. Fast Eddy is popular, but I tend to stick with Winter Evening bearings out of Alaska. They're good bearings and cheaper. If he doesn't have your kit, he will out together a kit for you. You can find him on ebay, but they also sell them on Amain and other shops.
