In a different thread, I posited that the front motor bearing on my 10EE is lubricated by fluid in the backgear/speed-reducer. One person commented that it isn't. Now that I have the motor apart, I have to question this again.
Here is a photo of the rear of the speed reducer. It has a slot in the lower left that runs from the interior, and it is below the oil level in the box. If you fill the box according to the sight glass, oil will flow out of the slot.
The next photo is of the front of the motor. Notice it has a matching slot and a channel that runs to the bearing. (Red straw in photo shows the channel.)
It is interesting that the top edge of the "oil channel" in the motor appears to be ABOVE the oil level of the gear reducer, so if it was suppose to provide oil to the bear then something is not quite right. On the other hand, the rear bearing of the motor has a grease fitting, but the front has none. If the lubricant in the speed reducer was NOT intended to oil the front bearing, then how did it get lubed?
