I inherited a speedster from my father in-ĺaw. There is a shift lever in the middle of the floorboards. Incorrectly assumed it was for a Ruckstell. Have not had time to truely look at things and today I noticed the diff. is factory but has a unit attached to the front. Any ideas what I have? I will be able to get pictures later.

almost for certain will be found to be this: https://mtfca.com/phpBB3/viewtopic.php? ... or#p172290

It could be a Moore or a Rocky Mountain 6 speed.
How 'bout some pics?

It might connect to a Warford auxiliary transmission attached to the rear of the transmission.

Sorry for the poor angles. I am working inside a tent with too many things piled up around it. Here is what I have.

I do think Scott is correct. Looks like I got me a Planitor. Now the fun starts...

It’s a Planator. It provides direct and 50% speed between the drive shaft and rear axle. It uses many model T parts. There is one completely custom sliding gear and one highly modified axle gear. All the others are regular T rear axle gears.
They work well but the 50% speed reduction is a little too much. JMHO

You know, Tony, I normally would not disagree with you, but you might want to consider the effect of retaining hill climbing ability while maintaining the ability to really GO when joined with a high speed ring/pinion and in direct drive. Too high a ratio can be a real dog in the mountains with a standard Ruckstell, but this would be a game changer. I think it would more replicate the extended range that a Warford gives but with only two speeds (which is a deficit in flexibility, for sure).

Given that this is on a speedster, this just might be the ticket...a Fordor, maybe not so much!

That’s my experience with the period 3-speed Warford in my speedster: the 50% under (albeit with standard rear gears) is perfect for going up and down 14-15% grades in Ford high.

Of course the Warford’s 25% over is pretty nice for flatlands and gentle downgrades…

Interesting as I had a Planator on the Town Car and found I really had to slow down more than I thought necessary but of course it depends on what you are use to. I believe the Ruckstell is about 60% reduction and they modified the KC Warford to duplicate that reduction on the their design.
It’s very personal and on the odd occasion when the Ruckstell won’t pull a steep hill, I agree with you
