No, it won't work that way. You should shim them so as the gears can still move freely but don't move side to side in the gearbox. I've found it to be a bit of a black art as they do need to move from side to side a "little" bit to rotate properly.

Basic idea is do one, close up the gearbox and put your finger in there and make sure it spins fine without excessive sideways movement. Then the next, then the next. If you google it there are plenty guides.

Make sure when testing that you screw the box shut for each adjustment, holding it shut isn't as accurate, if you have shimmed tightly without it shut tight you risk binding and or a less efficient build. There doesnt have to be equal shims on anything particularly as shims are different sizes. Take particular care when setting the sector and bevel gear as they interact with other parts aswell.
