12T pinion not fitting

[Kera]

Hi guys,

I received a robinson 12T pinion for my wheely king crawler but it doesn't seem to fit any good... The pinion is so small that the motor bumps on the top of tha tranny before I have a good mesh. (I run a 96T spur btw)

Anyone experienced this and has a solution ?

Let me know if it is confusing, I'll try to post some pics.

Thanks

That is a common problem with that gearbox
If you compare the AX 10 48P top gear

witch the 17mm/D 15T Modul 1 on the WK

You may have an idea of why it don´t fit



The WK top gear is larger and so the small pinon´s will only fit on a much larger spur gear
One of my friends use modul 0.5 100T spur vith an 11T pinon

i just took my dremel to the top of the tran. You don't need much off the top. worked great for me.

That's the same thing that I did with mine . . . .

Thanks for the explanation Snoop, and the feedback guys. I think I'll dremel the top and see how it works.

Slowly byt surely ! "thumbsup"

Just did it and it's working great.

The first run with my new Novak 55T and the 96/12 spur/pinion was amazing. What a change ! :)

Thanks again for the tip.

i had the same problem. same pinion and spur and motor. a lil dremeling changed a lot for the better! glad it worked for you!

Good idea, may have to do that with mine next time it's apart. Love the avitar too"thumbsup"

I would have just ran a larger spur, but a dremel works too.

would have ran a bigger one. but i still cant find one bigger then the 96T. do you know of one?

[The Real Dogman]

If you change to 32p gears you can go bigger dia gears and get a good mesh!!

I got 100-110 I think and the max with stock chassis is about 104 teeth. Allows a tiny pinion from the same place.

that were I got it. I didn't even look at who makes it. I've never seen one before so I just ordered it and didn't even look. They had up to 150T I think.

Anybody got pictures after dremeling ?

all i did was take the motor plate off and use a flap wheely on the dremmel and sanded the top off it is really quite easy. i now have 90/14 gears waiting for the 96 spur to come in mail. i had to grind the motor plat alot too

[clod & bruiser]

dang 150t....thats like -.5 mph

[nathanlima]

sorry it took me so long to make it back on this guys. I've been out of the state. All i did was sand it flat with the screws. you will have to make room on the motor plat too so the motor can go down.

Kinda hard to see. but it looks as though you were able to sand enough off without breaking thru the plastic exposing the gears?
Iam still waiting for the local hobby shop to get in some 12t gears.
Thanks for the pics it helps!!

[Kera]

Yep you dont need to expose the gears.

[Spot(T)]

Thanks to you all for the info and the pictures. Now I have a WK with 96/12 gearing, at full throttle it can reach a fast paced walk :-).
