The smoke smells a bit like the cleaning solvent. But that may be due to the fact that I have been at this most of the day and can only smell that any more. The motor housing is getting very hot after 10 mi utes of running. Hotter than it should I' m afraid.
Well, I would not have taken the motor completely apart, but since you did, I'm gonna suggest a couple things.
First: Make sure it's back together so the armature shaft does not bind. It should turn effortlessly.
Second: Make sure all the wiring is properly connected. A bad connection will reduce the current the motor is getting and can get hot.
Third: Make double sure the bearings are greased. Getting too hot after 10 minutes sounds like a lube problem to me.
Fourth: If none of this helps, you might have to take it back apart and start over. If all is well it should stop smoking.
Is the smoke decreasing any? 10 minutes of all out running, no stop, smoking motor is too long. A minute is plenty going full steam for testing. Does the motor operate the FW properly under load or is it slow and sluggish? Good luck.
Hi Kittys. If it's getting hotter than it should, there isn't enough (or any) grease in the motor's bearings. If it smells like solvent, you probably didn't clean all of the solvent off.
I'd be most concerned about the overheating: Solvent won't kill it but lack of grease will.
Too all the newbies this is where it's at concerning anything about sewing machine repair. Can't beat it.
