How often do you check you bearings?

I just grenaded the front bearing on my Neu 1512 1.5yf. How often should I check the bearings?
Thanks,
Brian

Honestly, when they grenade. I should and will start being a little more careful about checking due the expensive motors I have

i tare down my motors for cleaning and relube bearings on my motors every couple of runs, but im overly careful with all my motors, not just the bearings

Any particular lube you use? a link would be nice.

Thanks

You have to be careful regarding the bearings. If they blow out the race the rotor can become loose enough to hit the inner coils which would be bad news. You can grab the end of the shaft/pinion and try to move it, when the bearings wear out you will feel movement, a new bearing or one in good shape should have zero movement.

in and out or side to side?

That would be side to side, any movement in this direction could mean the actual balls or races are wearing out. Normally what happens is the bearing gets dry (no oil/grease) or dirty. Then the friction and heat cause the cages (these hold the balls in the proper position) to fail, which leads to major bearing failure. With In and out movement there is a little more play, even if there is movement in this direction when the motor energizes it will self align (center the rotor betwween the coils). Of course you don't want excessive movement here either, but a little is ok.
