Hey

I recently brought a SC10 2wd and have been driving it around and over a few jumps but nothing major and no major crashes. Then all of a sudden it starts making a gear stripping noise and i have stripped down and re-oiled the diff and stripped down the whole rear end twice now and and i cant seem to find the problem . Any help would be very appreciated.

thanks

did you check the spur/slipper

hey thanks for the reply and yes i have checked the slipper and spur gear and it is all in good condition with now wear marks or anything like that

is the noise just a click or an actual stripped gear sound.

if click its the diff. call associated and tell them you need new diff gears.


if not check gear mesh

If it has a the gear diff, then it is improperly shimmed. My brother got a brand new SC10RS and when he accelerated it made a stripping sound. We called Associated and they said that it wasn't shimmed right. They said they were going to send us shims with instructions but never did. Anyway, we went back to where we bought it and they gave us a brand new one and it didn't make the noise.

Email your address to AE and they will send you a shim kit. I added 1 shim on each side and it has worked flawless ever since.

these shims, exactly where do they go?

My daughters SC10 is doing that click click click sound, but when I took apart the gear diff, the only shims I saw were under the sun gears (the bigger internal gears, 2 of them) under the pin. On my 1/8 scales usually see a shim behind each of the smaller gears as well or at least we put those there when converting old rc8s to electric.

I recently had a buddy's sc10 rs doing this. A .01mm shim behind each planetary gear (smaller ones) fixed it up. Pretty common issue with the recent sc10.

thanks, that was what I was trying to do myself but didn't have small enough shims, every thing just locked up.

Do you have a part number on the shims themselves?

you can also add a shim behind one or both of the sun gears

no, I just had a kyosho gear shim set, don't know the number. I pulled a few out of there.

AE will send you the kit with instructions to you at no charge. It is very easy and probably a perfect time to set your gear diff up with new lube anyways. I have raced mine 15 nights plus practice since I installed the shims with no issues.

i fixed mine with more grease when it did it to me. but i still caled anyways and they sent me a complete rebuild kit

thanks.

Gave them a call and they are sending out shims.

They were however unable to identify a part number for the shims or the actual size exactly. No go on shims at the LHS either. Time to dig through the parts bin.

Funny, I was told the gear diff would be so much easier than the ball diff LOL.
