1910 EMF Pinion Gear Information

[redbaron1930]

Hello again;

   Now that I have a solution for my axles and bearings, I will need to get a new pinion gear for the car. The one I have now (with missing teeth) has or had 13 teeth. My 1912 operators manual says it should be a 3.5 to 1 gear ratio with the ring gear (which has 42 teeth). This would indicate that the pinion gear should only be 12 teeth, so I am not sure but i might have a modified model t gear in the car now (which has failed). My question is does anyone know what the proper gear is and possibly have a picture of the correct one?

 

  Thanks

The parts book shows 3 different ratios.

These pictures are of a scanned copy of the original 1912 parts book.

Good enough to know what was going on!

Layden;

   Thanks for this information, it certainly makes it clear that a 42/13 was an option for that year.

 

Thanks again

Glad to hear that you found a solution to your axle and bearings problems!  Hope you also find a solution to your ring & pinion needs.
