bally 1090 hopper locked up tight

[puckhead]

just buzzes on a payout. the wheel is jammed solid. releasing the brake does nothing  cant turn the hopper wheel by hand at all. . no stuck coins. do the gear boxes jam or go bad? if i try to turn the armature it spins freely.

thanks

old style hopper with the motor off to the side?


if so, you should be able to push on the nubs sticking out of the pinwheel and move the disc in both directions a little due to the lash/slop in the gears.  if you can't budge the pinwheel, time to take the thing apart.   The shaft could be cruddy or the dirt that accumulates at the bottom/behind can bind things up.


you won't be able to move the pinwheel once the gear lash is gone due to the gearbox torque.


the shaft sticking out the end of the motor armature/rotor shouldn't spin freely ... spinning that should slowly turn the pinwheel.  If the pinwheel did bind up, the motor may have lost some gear teeth.


the hopper motor is 120V, so you can attach a power cord to the motor winding lugs and plug it into the wall to see what happens.  If that works, check the payout relay contacts for burning/pitting/adjustment.  The payout relay switch wires are usually white and white/blue and there's two switches in parallel.  The white/blue goes to the hopper motor winding.

one of the 3 guide bearings for the hopper wheel cracked. i need another bearing . anybody have one??
thanks

oops ... you did say brake, didn't you ... so new style/snow hopper.


the bally part number the hopper bearing is M-1689.  Probably won't help unless one of the slot places keeps inventory with the bally numbers.  May be easier to just measure one of the ok ones and get a generic bearing.

its a snow hopper, but not a generic roller bearing. the outer race had a small groove machined into it, thats the guide groove for the hopper wheel.  i could flip the bearing, but  needs a groove machined into the flipped side.

Check for a jammed coin.
