Can Anyone Recommend A Supplier For Sewing Machine Repair Parts?
I have a old Singer Stylist 500 series (532) sewing machine that has finally given up the ghost. I am looking for two replacement parts.
1. Rotating hook drive shaft bevel gear, part no. 103363
2. Rotating hook drive shaft gear, part no. 153490
If anyone could provide a website or address or phone number to a place where I could buy these parts, I’d be very grateful. The owner is very attached to this machine and she doesn’t want a new one.

Try Ron Anderson at A1 Sewing: http://www.a1sewingmachine.com/
If Ron says the parts are no longer available, you might try the yahoo group wefixit — maybe someone has a donor machine.
Try http://parts.singerco.com. They have both industrial and home model machines and parts. If you Google Singer Stylist parts there will be several references, but try this one first. It might have what you want.
