I installed a cvrx on my TNX and it keeps chewing up the spur gear.I bought four in two weeks.I don't know if i'm overtighten' them.I even bought the Terra Crusher gears because they are supposed to be better.I know guys with TM's on their TNX and they aren't having this trouble.I'm just seeking advice if anyone can help it will be appreciated.Thanks

is everything the same? such as bell same tooth as stock, and you might have been buying the 44t spur gear one when the stock one is 43t, i dont know if its enought to mess with mesh. but it may

The guys with the TM's are running the Terra Crusher gear,and they haven't had any problems.

99% of all spur gear failures are due to improper gear alignment and mesh.

is your chassis flexed?

True, but if the three engine mount bolts are the least bit loose, the bolt holes will allow for a small amount of side-to-side movement. It doesn't take much to strip a spur.

I own a TNX and want to get the Terra Crusher spur gear...anyone know the part # on Tower Hobbies? I looked on Tamiyausa.com and I think the spur gear is part #50960 but i don't see it on Tower. I'm 'bout to place an order and would like to get this in so ASAP would be much appreciated. Thanks

I can't find it by itsself, but here is a tranny gear kit that has it included.

That is the only way you can get that spur gear. Even though the gear mesh isn't really adjustable there is enough play in it to set the mesh right. Set a piece of paper between the gears, set the mesh, pull out paper. It should look like a set of stairs without any tears in it..
