Be sure that the new gear is the same pitch. X.04 used brass while X.03 used plastic. I think the brass are 2 start while plastic are single start.

I was thinking the same thing. Plastic and brass can't always be swapped.

Mod edit. Topic moved to more appropriate section of the forum.

The only way of changing the plastic worm for a metal worm is also by chaining the gear wheel to one that is compatible with the worm, unless a third party supplier makes an exact metal equivalent of a plastic X03 worm
