I cannot get this motor apart!
 

I got the bracket but the troubleshooting continues on my Pfaff 130. The pulley is tight and I tried cleaning it well and oiling the ends and it was still very tight. I've removed the brushes and the 2 long screws and the two halfs should now pull apart. And that is not happening. I have tapped all around the center hoping to encourage it and it's stuck fast.

Are there any tricks anyone can share that would help? Maybe something like Miriam's spool trick and smack it with a hammer? :D

I don't know much about Pfaffs. Usually if I smack wood against metal it doesn't harm the metal. But you are on you own.

Pictures of the uncooperative motor would be helpful. I don't know how Pfaff motors are assembled.

Maybe they “setzen sie zusammen”?

Yeah, I used a bit of the wooed against metal. They are a normal universal type configuration but once I took out the long screws, it was a battle to separate the halves. The stupid part is the pulley was tight and then after I removed the screws it loosened up. However, the long screws have nuts on the ends and the nut on one side is under the Pfaff label which wouldn't come off. I finally got it apart last night and it involved using a clamp with wood blocks and a chisel...to a screwdriver, to other objects to wedge in the slowly expanding opening and twist.

Once I had it open I cleaned it, checked it over, and it was a nightmare to close. Now that it's closed, something it rubbing. I think one of the wires may have slipped into the way.

So I am going to have to open it up again today. *sigh

my least favorite thing on SMs working inside of cramped motor cased. brittle crowded, etc. But you'll get it cause tou're determined. Those old Hamilton Beach motors look intimidating, but wasn't so bad, as these things go, IMO.

I have a similar problem but on a 221K "Featherweight". Both the motor and the pulley are bakelite and I've tried two nights of putting Kroil around the area where the shaft goes through the Bakelite pulley (being careful it can't run towards the motor windings etc). I could (with a lot of patience and in tiny increments) get the other shaft out of its end but the pulley end doesn't want to budge. I've completely removed the screw that goes through it into the shaft and, as near as I can tell, this shaft doesn't have the "flat spot" like US-made motors.

Does anyone have some more ideas on how I might get it off without shattering the bakelite on either the motor or the pulley, please? I'm afraid of prying/twisting under the pulley with a screwdriver (or two - to even out the pressure) as I know these are renowned for being brittle and it only takes a split second for it to be too late.

Thanks in advance for any help or tips anyone can give.

This might sound unusual, and others have raised an eyebrow whenever I give this advice, but it works from personal experience. Take a clove of garlic, the fresher the better, and press it firmly against the stuck part until you see a drop of clear oil transfer to the part. Then, wait a few minutes remove the part. This method works on vehicles for me, even better than penetrating oil, so I don't see why it wouldn't work here.
