HORIKAWA ATTACKING MARTIAN MOTOR DRIVE GEAR ???

5 posts in this topic

Hello !  I was hoping to consult Alphadrome members store of knowledge--I just got a silver attacking martian from the sixties on Ebay for $50  I took it apart only to find that the only thing wrong with it is the small gear that attaches directly to the motor was shattered into a million pieces:blub: it was a plastic gear which is weird because all the other ones are brass or metal--Does anyone know the size and # of teeth that small gear has ??? I would like to try to replace it with one from ebay. The motor runs great and as far as I can tell everything should work !!!  Thanks in advance for any help anyone can give me !!!!!---Rich

Probably an 8 tooth gear.

Thanks for responding--I think I am going to try to replace it with a brass gear if I can find one small enough-Thanks again-Rich

It would be best to buy something like this which are good quality and will press fit easily on the motor drive shaft, pressing on a brass one would be a bit tricky with the motor still in position. Most of us here would use a plastic/nylon gear.

Thank you MRH !!! I  was worried about getting a brass gear on---this looks like the best compromise with the gear being reinforced ! I was thinking a regular plastic gear probably would not last very long !  Thanks again for your help !   Rich
