Gearbox ID

Post by tim.sanderson »

Hi all. I've been reading these forums for a while (mostly vintage kyosho & yokomo sections), but just signed up as a member today.
A few of us on another forum have been trying to id this kyosho gearbox. I thought the answer might be found here. :)
One theory is it's an incorrectly assembled Ultima gearbox...
Any ideas?

I'm guessing incorrectly assembled. Although I'm only using an Optima gearbox as comparison (and going from memory), it looks like some screws would not be going into the proper screw-holes. It looks like the large motor side-plate is on the wrong side. I'd venture that the gearbox should be bolted onto the other side of that side-plate. Don't quote me on that, though. :)

it looks to me like someone tried to assemble the gearbox in a mirror fashion, either to run it in a 'front drive' scenario, or with a mid motor configuration.

the motor plate looks reversible, and those standoffs look like they might be hand made.

That was one of my initial thoughts, too.

It's the stock Ultima gearbox to use midmounted motor.
