I bought a Tornado S30 off ebay as a project to rebuild. I have a Redcat Backdraft 3.5 buggy and love it I plan on getting the 8E soon as well as a few other Redcat cars seeing as I am an authorized dealer
. I am putting it back together and I am installing the differentials and the ring and pinion gears dont seem to be meshing together to well. They seem to be grinding bad. I dont see any shims or anything of that nature. Are there supposed to anything like that? Is there any way of telling how the mesh is between the gears?
There is a shim kit for your diff. I'm not sure of the part number, try sending Nitrosports a pm, he sells them. The gears shouldn't be tight, it's almost like setting your spur mesh. Also need to make sure your bearings aren't loose and giving you some slop in the pinion. They're not that dificult to figure out, there's really only three ways they feel when setting them up. Either tight, loose, or just right. Even one shim will make a difference.
