Stripped Gears On Tnx??

       Remove this ad - become a site supporter!
I bought a nitro tnx 4wd, and after the regular break in, on the first ride about 15 mins in, the transmission gear this a common problem?? i am new to the Hobby, i always has electrics, but nitro is a new world to me. Luckily it came with a replacement, but should i stock up on these things, or is it possible to get one not made out of plastic??

you mean the big gear (spur gear)? it can be prevented if the the clutch bell and that big gear are properly meshed together

It can be common on the TNX for this to happen. Biggest thing is to make sure you have all the engine screws tight as well as keep an eye on the rest of the chassis screws as they can back out and cause the chassis to flex and change the gear mesh that way. Also even though you can't really adjust the mesh there's still enough play in the holes that when you go to tighten the engine down push it towards the front left corner of the truck for the right mesh.

There isn't a steel replacement but you don't really want one anyways. But I would stock up on atleast another pair just make sure when you do that you try to find a shop that has the new style of spur for the tnx. It's the same part number but Tamiya has now actually widened the spur for more durability. If you want more info on the TNX come on over to

The main cause of stripping the SPUR gear is the 4 bolts that attach the gearbox to the need to tighten them every few runs( a good rule of thumb is to go over all screws on any machine after every couple of runs)

Since the TNX has a set gear mesh and cannot be adjusted(TNX has a SET Gear mesh) threadlock the bolts that attach the engine to the chassis....check every so often.

I have read and heard of stripped SPUR Gears, but I have ran 2 TNX'S for more than 6 months with out stripping a spur gear. The 2 sources of the problem are listed above.

i went to a local hobby shop, and they gave me 2 replacements at 26 bucks for both.... and the guy told me that the engine was perfectly matched with the tranny, like the gears are anyways...and i never tightened them...he did also tell me because of a 4wd truck i have to try not to hold the gas on while i land from jumps because of the power of the engine will cause it to strip....he said to loosen the nut holding it on while driving off road so the clutch would spin a ltitle instead of stripping.
