Please help!!! I have a kato 2-8-2t (BR 86) I use as a tank engine on my logging layout. The spur gear between the worm gear and the drivetrain has stripped in one place (not all the way). Any ideas out there for repair/regearing. I have already contacted Kato and they sent me to some places in germany but no luck for replacement parts. I have thought about building up the area w/ JB weld and re-filing the gear teeth, anyone with other ideas?
