If the shafts wobble from being loose, that will cause intermittent operation, if you can reseat them firmly they will work, if not, you need motor block 6105.100 to repair these.


I think they are the type where the drive shaft is rigidly fixed in the motor but I’m not sure. Is there a way to tell by a serial number or something?

Neither metal shaft appears loose or wobbly in any way.
