Ive had to replace the gears in my quad engine s a fair few times, its usually the drive dogs that wear, the case hardening wears off and once its through that they become worn and slip out of gear.

They use a combination of two gears so if it is that you have to replace two at a time so the corrisponding gears will be fixed

Good engines though mine are so reliable compared to other makes and bits are pretty cheap too
