    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?

    Northwest Shortline (NWSL) ( is a recommended source for gears and motors. However, I don't how good your chances are of replacing just the one gear - you may have to replace the whole set. is another recommended supplier. There is another fellow in Germany that does regear and remotor kits - I don't have his link on this computer. Also, I have heard good things about the makers of the Bull Ant drive (Hollywood Foundry, and similar products in Austrailia.

    I'm not sure about the JB Weld being the right hardness for a repair, but I don't see that you have much to lose. I don't see where the JB will cause any harm to the other gears, as long as all the grit was cleaned out before you tried to run the loco again.

    Another source of ideas and help might be the Yahoo remotor and regear group -

    I hope you can get it running again.

    I would think Northwest Shortline as Fred mentioned would be your best bet.
    You will need to find the Gear pitch and count the teeth
    This site may help.
    I have had some success repairing teeth on gears but I would only recommend it as a last resort.
    Is the gear metal or plastic?
    Years ago I built up the teeth on an old Chrysler flywheel with a welder and filed them to shape. It worked.

    Contact Northwest Shortline they are good at helping and if you do not have the ability to provide the detailed gear info you can send them the bad gear so that they can make one.

    The only draw back is that if it is a special it may cost more than you expect as they make the special gears by hand so to speak.

    I needed a gear for a Con-Cor 4-8-8-4 cost was $65.00, I think I got 2 for that price they had to make them special.
    I sent them the info on the gear, they sent me a quote (by e-mail) I had them make them, they fit with no problems.

    Gear replacement

    It looks as if I'll have to go the NWSL route, since kato was unable to help. I just recieved a second BR 86 in the mail from a ebay auction, thought about molding and casting another gear from the good one out of the new loco. I'll be giving NWSL a call on monday, just hate spending half as much as a new loco for a gear. Thanks for the assistance.

    It could be that some one before you has already ordered this gear in that case perhaps NWSL has the blanks & program for cutting it.
    I would think if that is the case the cost may be less?
