- It did this with the Ball Diff and the Gear Diff - And with the old Tranny case, and the new Tranny Case. - Checked Spur and Pinion, perfect, pads, plates, fine. - The only thing I see is the Topshaft is wobbling a bit. But it goes into the tranny smoothly. - All bearings are solid and free spinning. It's odd to me. It drives great, It's not causing any drag either. Only an extremely obnoxious "broke" noise. |
Gearing for my first off road race ever.
Good day!
I just bought an sc10 2wd last sunday and have been busy fixing all the things wrong with it. I am going to a my first off road race this weekend and would like some help with gearing. The motor is a castle 4600 4 polel and the speedo is a mamba max pro and it has a ball diff. The spur is an 81 tooth. The track was started to be put down today so the surface is anyones guess. Here is the layout of the track. http://www.rctech.net/forum/10360644-post109.html Thanks, Neil. |

Can you take a quick video so we can hear the noise. Check the motor plate screws, if one is too long it could rub the slipper...

Transmission Screws are floppy loose, and the noise remains. Not the motor either.

I couldn't see the video on my phone but make sure the inside slipper plate isnt rubbing the motor plate.
It's not a metal screech grind. You'd have to listen. it's plastic tap at high speed is the best I can describe it. |

check you diff and make sure you not missing something..it also sounds like a spun rotor on your motor...check your motor
the motor spins great, no sound. |
It may sound great under load but it may cut loose with the pinion connected to the spur. Its a pretty horrific sound when I have heard it. Have you tried a different motor yet?

Its a huge load compared to just a pinion. Re-reading your post, if you have a bent top shaft it will make quite a racket too. We're throwing out suggestions here. Don't knock 'em til you've tried 'em.

Well your safe. A real addict would be in the car driving 4 hours to find another track. A true addict will get their drug at any cost

I said in my original question, that the ball diff and my brandnew gear diff both were present during this noise.
the motor spins great, no sound. I am 80% sure it is the Mesh from the top shaft to the idler. I have this same noise in my B4.1 tranny after I replaced the Idler and top shaft along with new Avid bearings. also tested with old bearings. Even installed old parts back in noise gone. new parts noise back. Not sure 100% what it is with the gears but I am pretty sure its the idler to top shaft gear mesh. I also tested it with 2 different ball diffs and 2 different gear diff's same noise |
I bought a Factory Team SC10 and it came with plastic rear hubs, was it supposed to come with aluminum? I thought it was just like the B4.1
