Do you mean when you try the balance wheel, it kinda rocks back & forth slightly? If so, then from my experience this is caused by hardened grease around the worm gear, bushings, etc. Quick way to find out if the motor is the cause is simply remove the motor housing (those two screws Leon mentioned), internals should now spin freely
ps: i suspect hardened grease
