ENGINE GEAR - O-TYPE

The engine drives the gun with the help of gears. The gears have two types of fastening, type O and D. Their variation and placement depends on the design of the motor shaft. AD type motor gears are fastened from the side with a caterpillar screw, while O type ones are fixed by strong pressure.
In the case of electric airsoft guns, the wrongly adjusted motor height can greatly shorten not only the motor gear but also the life of the motor. This should be set up by a competent mechanic.

IMPORTANT: Before buying, make sure that the motor needs an O or D type gear!
