These differential gears were in a Ruckstell differential I recently acquired. None of the gears had any markings. Anyone have any info on these?

They are Scurlock differential Gears, They were made by Ruckstell. They were Auxiliary parts for the Snow Flyer units. Would you be interested in selling them. Been looking fore a set for my snow unit. PM me.

If you have the complete page can you see the date. this would have before (note Patents pending) ruckstell acquired the patent rights. My info. comes from a 1928 Snow Flyer parts list.

It would be neat to see if these could be reproduced. How do the internal splines work into this arrangement? The original side gears are smooth and a press fit.

These remind me of Mopar's limited slip differentials.

Dave, the differential & gears in the advertisement Jim posted are for TT trucks. TT axle shafts are splined, also note the TT differential has four spider gears. The T car has three.

As far as having them reproduced; I've examined how they work, and the forces and loading on the spider shafts as well as the gears themselves look to be very excessive. As a matter of fact, I wouldn't be surprised if lots of these broke and tore up the rest of the rear end in the process.

It kind of looks like a poor design to me... (way too small for what it is supposed to do) However, I think the TT version might work just fine in a TT that doesn't actually get loaded with anything.

I'm not sure I understand how they are supposed to work. Looks like you could still have one wheel spinning and one sitting still. Anyone care to shed more light on these?

Here are the T and TT Scurlock gears,
