Kato 4-6-4 problems

[NP284]

I have a Kato 4-6-4 that recently broke down and I'm trying to get it back in operation. I've searched the internet for gears with not much luck. Can anyone out there recommend a place to purchase the worm and drive gear for this or anyone with the parts I can purchase? Many thanks for responses

You can give Con Cor a try. They're the ones that originally imported them. Other than that, you'll probably need to find a donor engine.
