Got it tunes in right.. Now i am having transmission problems. I took it all apart and everything seems to be in place. Replaced slipper clutch (72 count), new bell housing (21 count) got mesh down properly too. BUT... When I hit the throttle, it revvs up and nothing moves. Got slipper clutch to the max torque just to make sure its not slipping. Truck moved some but nothing like it should.. Also, Brake/acceleration servo is not pulling on the brake side hard enough.. So I have no brake. I am htinking this is an adjustment on my JR X3 Pro remote but am looking into it. right now, I'm still a week into this re-build project and truck has no more than 5 minutes of run time. I am so lost on the tranny problem.. Everything looks to be great! But no movement.. at least not like you would expect..
That's the issue with getting a used R/C, it can be overwhelming. But, don't worry, don't give up, once you get it you will love it. You said when you throttle up nothing moves, is your clutch bell moving, even at an idle? That's the first step, if that is not spinning then you have clutch/flywheel issues. If it is spinning we move down the line, ok so Clutch bell is spinning, is the spur gear spinning? You said the mesh was good, and if the clutch bell is spinning the spur should be. Ok! spur gear is spinning lets see, what about the pegs that hold the spur gear? I have actually never taken it apart before so I don't know what to expect.
Correct me if I'm wrong, But I'm pretty sure when you take that nut and spring off the spur gear, you get rubber pegs that are smooshed in between those plates on the spur. and I have read about those pegs wearing out, maybe that is your issue? Ok, good pegs and spur! Now to the tranny. You said you got the truck to move, How did it act? was it just jerking forward? or was it rolling? Hear any weird noises? Have you played with the wheels at all. Spin both of the front tires at the same time, hear any clicking? Feel resistance? Do it to the rears afterwards, same deal, clicking? resistance? other noises? When you are spinning both the front tires, what are the rears doing? What about when you are spinning both rear tires, what are the fronts doing? Roll it around on all wheels on the floor, Do you hear any bad noises from the tranny or diffs? If you can do all that with any problems your tranny is probably fine. The diffs in my Tmaxx click pretty bad and I didn't notice anything until I pulled the diffs out of the truck and played with them.
About your throttle and brake problem. I would reset the transmitter to all default and then your going to have to adjust the linkage if it is still not correct. Adjusting the throttle/brake linkage is a pain, I still don't like to mess with mine.
Whew, that is one wall of text. Just trying to be thorough, I want you to get this truck running.
