Cuando aprieto queda una holgura considerable entre la cabeza del tornillo y la seta, incluso las arandelas las puedes mover con las manos pero la campana queda pegada literalmente a la masa, no se mueve libremente hacia delante o hacia atras... estuve viendo y repitiendo el montaje una y otra vez y nada. Si alguno sabe lo que puede estar pasando se lo agradezco... muchas gracias! Un saludo!
puede ser que el cono largo, parte numero T2707 no este fabricado bien. Avia alguien aqui que anterior mente reporto que esta parte tenia el aujero fuera del centro. Fijate mirando a esta parte asi al aujero, si el aujero esta a un costado de unos de los lados entonces es esta parte que te esta dando problemas. Suena como que ay algo que no esta exacta menta entrando bien, o esta mal fabricado.

otra cosa que puede ser, fijate si parte T2705 esta apretado asi adentro de parte T2704, la primera ves que arme el centax no aprete esta parte bien adentro.

First race weekend: good news, car handled great! Bad news, I went through two sets of NT1 diff gears in the rear. Has anyone figured out how to shim the NT1 gears?

You old bugga you.. YOU SAID YOU WOULDNT!!! Looks like you and I will have to have an ancients race, MTX4 versus G4...

Congrats Greg, I'm so happy, just thinking of B and Grandpa building a schmick car together... It's not just about the racing!

Ahhhhh I got it now.... You make a bet with him if he didnt come off for 20 minutes... Nice move B! G was happy as a HAM in SPAM that night, well deserved

Super happy for you both.

PS: Greg, wont ever forget my first meeting where you showed me the inner hex on the ball joint and made me realise these things are for real!

nt1 plastic pinion gear tool fits perfectly but only works for 15 16 20 and 21 teeht, no 14 or 19

a friend of mine mentioned to me that the nt1 gears are a bit taller so he had to compensate using .6mm shims in total (.3 each side) if i recall correctly

Did you blow metal, or plastic NT1 gears?

I used KM diff gears and race this weekend without a problem.

There is just too much force for these gears to hold ! They were all blowing with electric brushed motors(7t), they can't handle 4.5t brushless motors, so what makes you think they will last with 1.2+ horsepower .12 motors ! My Nikko gear diffs looked way tougher .......

The gear diff cases , the screws, and the gears need to be made in thick balanced titanium 6al4v, for the system to last long ! It also needs balancing after every build, using the same bearings that will be installed in the car. It seems that the current internal gears get out of balance with all the experimental shimming going on here: at a certain speed the internals eat each other up !!!

Diff balancing, as rotating mass is very important ! Symmetry around the diff axis changes with shimming and adding different weight oil. It gets really complicated when adding centrifugal forces to that mix, resulting most of the time in a blown diff, after all efforts have been exhausted . I say stick with a spool up front, and a solid ball diff in the rear ! Or if you must use a diff, try to learn from the Russians with their Awesomatix sealed, oil filled, and adjustable ball diff running 16 ceramic balls !
