The top to bottom is about 1/16 of an inch. So, should I replace the bearings?
I got a lot of noise with a 30:1 dc motor so I thought that it must be too much play with the gears and axles. I ordered a standard dc motor and the is far less noise. However, I still think that there is too much axle play. But, I am not going to do any thing about it. That is why I bought a second 312.
