"The noisiest part of your geartrain is the motor/bevel interface, due to the way the two gears come together under pressure. If your motor cage is perfectly aligned to your gearbox shell, you'll have a good interface angle between the bevel and pinion. Once you've accomplished this, it's a matter of adjusting the bevel height to establish a perfect mesh between the two. You test this by rotating the bevel gear once the box is assembled without any other gears installed. Shim tiny bit by tiny bit until you have exactly enough shimming to reduce any lateral play.

It's a staggering amount of work, sadly. More by a wide margin with these gears than with any other kind of gear. However, if you're looking for precision, it's worth it. In my custom PK-S rifle, this bevel set gives me almost instant trigger response, an almost silent gear lockup under full-auto at near 30 r/sec rate of fire. I've had less than exciting performance with helical gears in the past, but with the fact that motor and bevel gears can be shimmed in two dimensions rather than just one, this mod is one I HIGHLY recommend as an effective way to reduce the noise of your gearbox, but mind that installation is extremely advanced.

"These gears are very quiet and mesh very well if you know how to shim properly.
