Imperial 520 Sewing Machine Repair

I have a vintage Imperial 520 Sewing Machine whose mechanism is stiff, and wont run freely, to the point where only cranking by hand works - too much for the motor.

I have narrowed down the problem to the drive shaft that spins the bobbin holder 180 degrees - it’s quite stiff. I tried 3in1 motor machine oil, but that made it worse.

I’d like to take it apart and give it a good cleaning, but there is a cam attached to the shaft by some kind of pin (see image, center, a little out of focus)

.

So, my question is how do I get that pin out (or otherwise remove the shaft, and then how do I clean and properly lubricate that shaft?

Thank you.

@jonathonmckay you need a drive pin punch for that. Something like this you get them relatively cheap at home depot etc. After that check your shafts for any sign of having been rubbing against a worn bushing etc. Use some grease to lubricate since oil will most likely sling off when you use the sewing machine.

Had a look at the link you provided. I'm guessing I use those to basically bash ... uh, tap the pin out with a hammer. Thanks, I'll give it a shot.

Yep, give it a try and happy bashing. Some of those are tight....

Totally worked!

Actually, I used a nail set. A couple taps with a light hammer, and the pin popped out far enough I could remove it by hand. Cam needed some convincing to come off, but used the same tools and I'm set!

Thank you!

@jonathonmckay that is great. Thank you for accepting my answer. Now the fun part. As you continue to work on your sewing machine, make a guide for it. https://www.ifixit.com/Guide/new that way others can maybe fix their machine as well. Those are speciality guides that will be really useful.
