Hello ,

would someone know how to disassemble this pulley? I specify that there is no more screw which retains it

thanks.

Well done! I put a 250mm pulley on my 69. Brilliant with a 45mm on the servo.

Let me guess, the screw in the middle of the wheel? I have forgotten that one a few times, wondering why it wouldn't come off after taking out the set screws

this is exactly what I am doing, however, on the servo I did not find a 40 / 45mm pulley. if you have an address to give me I am interested

On aliexpress the pulleys are widely available. I recently purchased this one in particular and have found it to work quite well, plus they are extremely affordable. So far I have not found anything I can fault it for. Probably these are the exact same pulleys you buy from shops in the west, except now you buy straight from the manufacturer and thus they cost 10x less.

45mm seems to be the smallest size available, and as far as I know the shaft diameter is pretty standard on sewing machine motors, so it should fit yours as well.

Sorry, I lied, It's a 40mm pulley not 45mm. I don't remember where I got it, I had it already but It had a shoulder on it that I had to chop off before I could get the securing nut on it.

on my machine the shaft diameter is 13 mm and it's difficult to find this diameter on the pulleys that we see everywhere.

how did you solve the problem?

Servo shaft diameter? Can't remember my details because I did a similar conversion on my Durkopp239 but they are out there. You can even buy pulleys that you can bore out yourself.

Try Googling 40mm/45mm sheave instead of pulley.
