whats the difference from the old and new spur gear?

MartynD

I thought it was diff gears too thick, not the spur gear...

Haven't seen anyone report the spur was too thick..

Neil

Sorry I meant the ring gear its the one with the diff balls in it. You can take your calipers and measure the thickness of the ring gear. I dont know what the spec is offhand but the overly thick one was causing my diffs to lock up midway through the run. If you have some spares from your old tc3 they will work fine.

oh maybe i read wrong so whats the difference then?


from the old and new diff gears.

MartynD

The new ones and the ones you would buy as parts are not as thick, permitting the balls to ride properly on the rings.

In the kits the diff gears were slightly too thick not allowing the balls to ride on the rings properly, associated has acknowledged the problem, if you believe yours are too thick, if you call AE with proof of purchase I think they will help ya out.

Ive tried this on my tc3 and I dont think I did it right. The problem im seeing is that the ball stud will "drop" down into the knuckle and only screw in on the last few threads so its weaker. Sometimes I can just pull the whole thing out, thats how I know they are stripped or they just wont tighten. But I will mess with it and see if I can get it all fixed w/o having to go to aluminum. Or at least till I quit hittin stuff

MartynD

Try using CA at least to make it last until u buy alu

That will help , that may be why guys running 27t and I'm running 17t is faster then me.

MartynD

Try going with a larger pinion before changing the spur gear...

Check AE's recommended gear chart as a starting point. Also could be your motor needs a rebuild.

Javen13

are you running the same pitch gear as the other guy because 10teeth is a pretty big jump

just wondering what shims everyone is running under the hinge pin mounts? Stock setup or? I did actually search the forum so dont go nuts if its already been asked. Running rubber on ozite on smooth moderatly tight track setups.

That other person may also be running 64 pitch gears too.

So here's something I came across talking to a lot of different people on the TC4. Flex is an issue, that's been talked about over and over again. One driver even said he is able to flex the graphite arms in his hands. Would it be possible to simply retrofit the TC4 with FT TC3 arms and use the TC3 Swaybar mounts? Seems like it "should" fix some of the problems. Any thoughts?

hey guys,
i did alot of testing today with the BMI TC-4 carbon fiber chassis kit.testing went very well.the car carried alot more coner speed and was extremely consistant.i ran it with a 8x2 and i could almost drive it with my eyes closed.it was so smoothe and did respond very well to even the most slight adjustments.my only complaint with the car is that its pretty brittle.on occasion that i tagged a pipe it was almost certain of breaking.it took me a bit to get it set up but once i got it she was so nice.all that i am lacking now is a swaybar.even without running a swaybar on the front or rear on high bite asphalt,it still didnt scrub the sides of the chassis on the bottom.it carried so much speed through the corners without getting squirley and was very,very consistant.the car felt the same every lap and i could hit the same lines every time.i am very pleased with the car and feel that this kit is ready to go to production as long as carpet testing went as well.
