Magic bullet motor died will no work when cup pushed down . Nothing seems to be broken off

SOURCE: My Magic Bullet has broken. I need to know how to get it fix.

This happened to me, and I was told by the company that I had to purchase a brand new base, that the plastic turning device can not be repaired. If it is under warranty, you may not have to pay anything but shipping, and maybe not that either. If you do not have the number to the company, go on-line and and search for it. Call the company and report what the problem is.

i had the same problem,broken plastic drive gear.
solution ; sacrifice one of the blender choppers bases you use the least (usually the flat cutter)
hold the cutter blade with pliers or in a vice if you can and unscrew the rubber gear off the shaft in a clockwise direction -- CLOCKWISE--DIRECTION-- easy huh.
Now insert screwdriver to suit,(coss,phillips or flat blade type) into centre hole in underside base of power head drive unit. Hold unit firmly and now unscrew broken gear or brass centre piece left behind CLOCKWISE again off spindle.
Finally screw rubber gear back onto motor spindle in ANTI clockwise direction. DO NOT over tighten. Rotation of motor and drag caused by blending action tightens assembly with use.
Done. for pics follow this link
