If you have turned out the bottom pivot ball you have increased the track width (could be over 200mm). I can tell you now, if your a millimeter off when you did it, your car will be all over the place thats why its better to leave the bottom ones fixed and play only with the top ones.

With your question, yes, they will have some slop. The pivots need to rotate freely or your suspension won't work. I spent endless hours trying to get them slop free and still allow the balls to pivot easily, never could achieve this. Alittle slop will not hurt.

Im not sure what your actually what your actually adjusted, the pivot balls when adjusted will not change the slop, its the only the retainer that do (ie the large hex type that requires the large allen key to adjust)

Actually nevermind, i'm stupid, I was missing some extra parts. Got it figured out now, thanks.

Let me guess ..... The little concave plastic spacer that goes inside between the pivot and retainer - I always do it

guys
I know that I need to use a digital caliper to set the kawahara micro centax.
What else do you suggest in way of building this?
And also the kawahara negative diff what diff oil to use
and what setup for the whole car you have found to be the best starting point.
using foams on a very smooth aspalht.
no traction compound though on the track.

I'm hoping the MTX3 tranny will fit the MTX-2. I've got the Kawahara 2 sp on it now, but I keep having problems. First, it developed a "wobble". Almost like the shaft had worn down were the bearing rides. I was in the process of figuring whether the shaft was worn or the bearing race had worn down, when the damn bearing in the housing seized on me. I'm thinking (right now) hopefully it was a bearing problem all along. So now I just ned to get the bearing out and replace it to make sure.

If the MTX-3 tranny will fit the MTX-2, it might give me some different gearing options as well.

I put 5000 weight oil in the negative diff. I also had to decrease my rear toe in because of the traction this thing put down coming out of the corner. Our track is medium to low bite, but I'm only running about 0.5mm of rear toe in. Any more than that, it pushes the front too much. You're probably gonna have to play a little to see what works for you, depending on your track and car setup. BTW. start with the factory settings, it's a pretty good "neutral" setup.

thanks teksrq,
how about the micro clutch any special way of building it?
is there a thing I need to watch out for when building it?

stefan

it's the shaft buddy.

I had the same problem. The shaft material is too soft.

I was lucky to find a replacement shaft, but I'm looking into an alternative solution.

Also, the bearing in the second gear bell is crap. Replace it and it will be much better.

tekrsq

Can't help you there. I'm using the Mugen centax.

gooseman271

yup

tekrsq

Damn, you think it's the shaft? I haven't had a chance to pull it all down and measure it yet. Where did you get another shaft? I've been told by everybody that deals Kawahara there are no replacement parts.

stefan

Once you got the two spur gears off, you'll see the damage with your bare eyes (if it's as bad already than mine)
The one-way bearing wore a groove in the shaft so bad, that I couldn't get it off anymore.

Try Castle Hobbies (RC Imports), they are the importer off Kawahara. They usually have spare parts.

I have problems with the K 2 speed also. Remember I asked about the squealing noise? Well it appears that the shaft has worn too small in diameter and the 1way bearing is slipping.

Sydewynder

Where did you find a replacement shaft for the K 2 speed? Help me stefan!!!

Sydewynder

Didn't start anything. Just stated my opinion. People need to read that thread from the beginning.
