Setting Gear Mesh?
 

How do you properly set the gear mesh? I already chewed up a spur!

take a piece of lined paper and put it inbtween the spur and pinion and jm it down tight and tighten the screws.... then u should have a perfect mesh

Sometimes, it's not a static mesh that the issue. You can have a perfect mesh when the truck is standing still, but if the motor mount flexes with jumps or whatever, the mesh will be affected. A solid, consistent is VERY important to the life of any spur. What kind of motor mount setup do you have?

Another thing to consider is that most spurgears have got an off-centre hole in them. The paper trick works in an ideal world, but with an off-centre hole the paper needs to be on the place where the gears are as close as possible.

Can you please stick to one account? or use one only? this is rather confusing.. :)

put a thin piece of paper between the gears and push them together. then tighten it up.
