Installation of Pinion Gear & Gearbox:
It will be necessary for you to install the pinion on the shaft if you are using a gearbox.
When installing motors into the E-flite gearbox, it is very important that your gear mesh is correct and the gear’s
mesh is smooth with no binding. The E-flite gearbox features adjustable slotted mounting holes so that you can
ensure your gear mesh is correct. Remember, if your mesh is too loose or too tight, it may strip the gears.
One suggestion may be to insert the polybag included with the motor or a small piece of paper in between the
pinion and spur gear as you are installing them. Tighten and secure the screws to the gearbox. Always make
sure the screws are long enough so they have properly seated into the motor. You can easily pull the polybag
or paper out by rotating the shaft until it comes out. Be certain to check the mesh at multiple points on the spur
gear before finalizing the motor mounting position in the gearbox. To extend the life of your gearbox, we also
recommend using a small amount of grease, such as lithium grease, on the spur gear.
Once a pinion is installed on the shaft, it will be necessary to remove the pinion from the motor shaft if you want
to use the motor with a gearbox that uses a different module of spur gear. If not, the gears may bind and the
motor will not operate properly. We recommend using a gear puller for this step (EFLA212) for the safest
removal of the pinion gear. Never reuse a pinion gear that has been removed from a shaft.
Installing Pinion Gear
1. Align pinion on end of shaft and press fit using a vise for proper installation.
2. Support the aft bearing and shaft using a small hardwood block to prevent both from separating from the
case.
3. Be careful you do not crimp the motor wires in the process and make sure they are safely out of the way.
