Question about rc

[Daniel C]

So I have this rc that I ended up getting as a payment for a small job and I need a gear that goes on the motor that fits to what I think they call the spur gear but I'm not shure what kind of rc this is so can anyone help with that?

I have no idea what this kit is but the gear you're after is called a pinion gear.

Ok that still helps and I do appreciate that. So do you mabey know of anywhere else I might could gather that knowledge of the right size and tooth count? I asked this question before here but forgot what was said and I can't get back to the post that was about that. I can't even remember the members name now that helped me. To much going on lately. I have this rc and a two wheel drive with the same problem. Both are ready except the electronics and that pinion gear. The two wheel drives 540 8t will be here tomorrow. Thanks again Graywolf74

You need to look at the spur gears on those kits and find out what gear pitch they are in order to know what gear pitch pinion to order. The typical ones are Mod1, 32P, 48P. You should see stamped into the spur gear some sort of Module, Mod, or P number. Once you get that then check back and we'll tackle the next step.

I looked it over really good and no number or no stamp at all. I went on to Amazon and found a set of pinion gears. I'm hoping one will work. I haven't bought them yet I thought I would see what you think first.

Its really hard to tell from a pic. Usually the pitch is stamped on the spur gear but then again most spurs are plastic and this one is probably after market. With no stamp and no ID on the kit itself its going to be down to trial and error. (BTW, did this come with a body of any kind? If so is there any labels or stickers on it that my provide a clue as to its manufacturer?)

Anyway, back to the trial and error part. What I would do is buy 1 pinion of each pitch. 32p, 48P, and a Mod1. You could probably skip Mod1 initially, this looks like a 1/10 scale electric kit which probably means its not Mod1. Most likely its 32P or 48P. Lets hope its not one of the less common pitches like Mod .6 or Mod .8 but lets not get to far ahead of ourselves. As I was saying buy one of each and just find the cheapest ones you can as this will mostly be for testing purposes. Once youve tried them together and see which one seems to correct than we can temporarily test with it. Once you get the pinion on there and the mesh seems correct then run it. Watch and make sure you're not seeing metal shavings around your spur and pinions gears after a few packs. If you start seeing metal shavings then you have gears of 2 different pitches that are very close but not 100% matched. For example 48P and Mod .6 are so close that just mounting them up may seem like they mesh but after running them together youll start to see signs of incorrect wear like metal shavings.

You know after having said all that it suddenly occurred to me that the easier thing to probably do is take the kit to your local hobby store and have a tech or someone really knowledgable to look at it. They can probably tell you what it is without you having to guess. They probably even have some spare pinions to test it out with for you to double check. IDK why I didnt think about that first but either way should get you were you're trying to go. You local hobby shop (if they have a really knowledgable tech) may even be able to ID the car for you which you're going to need to know sooner or later in order to find replacement parts.
