Speed 400 motor
I have been flying nitro for a long time, but bought a little electric for one of my kids. With the plane, I purchased a speed 400 motor and with it came two pinion gears. How do I press one of these gears onto the shaft? Also, is there a proper way to break in a motor like this and does it ever need lubricated?
Thanks,
Paul

RE: Speed 400 motor
Here's some info gleaned from elsewhere. Pictures don't seem to be in the correct order.... Can't recall who posted it orgininally:
Pinion Installation
1. Use a large C-Clamp to press the pinion onto the shaft as shown
2. Press the pinion to the point were it is flush with the end of the motor shaft.
3. Use a 400C pinion or something with a hole larger than the motor shaft (2mm) to complete the next step.
4. This image shows using a 400C pinion (it does not matter which one) to press the 300C/350C pinion further down the Feigao motor shaft. This process will work with GWS motors also.
5. This image shows the pinion properly positioned on the Feigao motor

RE: Speed 400 motor
To add to the above, you want to ensure that when you are pressing on one end of the shaft, the restraining force is being applied to the other end of the shaft, not the case or the bearings.
Using a pinion with a larger hole can be used to press the pinion further down the shaft.
If you are going to lubricate the motor, use only a tiny little bit on both ends of the shaft where it goes in the case. I don't apply the oil from the can. I put some on plastic wrap and then use a wire from a twist tie to pick some up before applying. Use a light machine oil or something like 3 in 1.
You can break them in in a glass of (preferred) distilled water. Hook up the motor to a D cell battery and let it run for 10 minutes in the glass (Just the motor and part of the leads goes into the glass, not the battery!). The water will get discolored. Drain the glass, fill it up again and run it for a short while to clean out the rest of the dirty water.
Let it dry well, then lubricate as above.
