I was jsut reading a small sheet by systema on how to adjust a motor. Systema said that their was to fit a motor in properly with a bevel gear is to put nothing in the gearbox except the bevel gear and attach the motor and then adjust it till theres no more noise.

So, I'm used to just putting everything together and shooting the gun off till i think its sounds good, that generally works but I want to know the best way.

So i tried the new systema method; After adjusting the the motor the sound is really smooth. After looking at how the gears interact on to why it sounds so smooth, the bevel gear is not completely all the way in...maybe 3/4 of the pinion gear is actually interacting with the bevel gear. Is this correct or should the whole pinion gear be inserted with the bevel gear?

I am wondering because when the whole pinion gear is touching, but (not all the way in pressed against the bevel) there is alot of sound but when 3/4 of the way touching it makes perfect sound.

Then, I am concerned that the pinion gear is now having to do more power to turn the gears because it is not 100% touching.

So my question is, Does the pinion gear have to be 100% touching the bevel gear to have 100% efficiency?

Thank you for the input,
