I believe they are 1/16"

That's what comes up in the description.  I don't envy anyone who gets into this part of the machine.

Hello, @DanishMan

Can you tell me where this ball bearing part (91-019 657-05) goes? Is it housed inside that bushing part 91-019 656-05? I have to change my presser bar. I still haven't disassembled it yet, but now as it is I can't see this ball bearing part. Do you have any photos of this ball bearing 91-019 657-05? Perhaps when you were installing the little balls for the bearing?

Best Regards,

Hugo

I would suggest you use some sticky grease as part of the assembly process. I have had to use grease, tweezers, and a dental pick to assemble needle bearings.

Hi Hugocraft

Sorry for my late response.

If you just remove the presser bar, the metal balls will fall out.

91-019 657-05 is housed inside 91-019 656-05. 

It has been a long time since I did change the metal balls of a machine, but I am going to pick up a 145 on Monday.

As I remember the ball size is 1/16 inch.

You can probably retain the metal balls inside the ball bearing part, if you insert a temporary piece of the same dimension as the presser bar.

Cheers

Søren
