All the gears have a set screw. You just are not seeing the whole picture.
The plastic is molded to a metal part that fastens to the shaft with a or 2
set screws depending on the gear.

> Repair - bevel gear / timing Singer 2112
> Hi!
> Anybody here savvy about repair?
> My sewing machine jammed in use, and I found that the timing had
> slipped. I opened it up and noticed that the bevel gear on the
> horizontal shaft is turning freely despite the shaft. There is no set
> screw there - I think the timing adjustment is on the helical gear set
> screw elsewhere on that shaft (true or not?). So the bevel gear must
> not be meant to slip. Is there a torque-limiting clutch that can be
> adjusted, or is something stripped? I see several screws that might be
> adjustments.
> I don't have the money for a repair shop these days, and I don't have
> the service manual, and the answer is not apparent, so I would
> appreciate any help that is available.
> Thanks!
