I know that the steering ratio in 26/27 changed to 5 to 1. Which changed the size and number of teeth in the center steering gear.
Why aren't the shafts of previous years compatible...is there any way to convert a previous year shaft to a '27 shaft?
Thanks ahead of time,
The central gear and 3 planetary gears are changed for 5:1 ratio. The earlier cars are easily changed to 5:1 by changing out these gears and the steering shaft. Note that the shaft must be changed also, since the centers between the planetaries and the central gear change. BTW, the 5:1 gears will fit into the earliest brass gear housing just fine. I'm currently running this set-up in my 12, for better jack-knife control.
Thanks, Seth.....appreciate the diagrams!
Sorry......didn't mean to leave you out Scott!
Appreciate the answers.
