Be careful with that — the machine is already going to be mostly metal, but they made that part plastic for a reason. Most presumably, because it would be difficult to oil it as needed as time goes on.

I have a vintage Bernina with a plastic cam gear that also can break over time — still going strong! People have figured out how to mill new ones from plastic, and are experimenting with strength of resin-cast and 3D-printed versions.
