  • Low Ratio
  • I have seen a couple of these over the years stamped on the transmission But have not had an opportunity to open one up to check out the differences. Can anyone shed some light on this. The couple I have seen have been 9n's so I assume it may have been an early special order? I would also assume that it had to do with trans gearing cause if it had to do with pinion gear I would think it would have been stamped on the rear housing lip not trans lip

  • HiYa Kirk-
    I have seen this before and have concluded it is not a factory 'special' but rather someone's marking of perhaps a Sherman or other auxiliary transmission system on their tractor. No documentation exists to verify this so I highly doubt it is OEM. Further proof is the hand stamping numbers and characters. FORD Hand Stamps used the capital letter "I" for the numeral #1, and the #6 was a lower case letter 'b' and the numeral #9 was an inverted lowercase letter 'b'. Additionally, look at the number '3' stamped on the housing and compare it to the number 3 used in the official FORD Hand Stamp kit. They are different fonts. Also, the 0 (zero) and 8's are questionable as well. So, that is how I see it. The 3 and the 6 are NOT the same for sure. The 1 is NOT an "I". You can't dispute the facts.

  • First one for me.
    That's on a 9n?
    Early with the straight cut gears or later?

  • I believe the one in the photo is a 1940 9N which would be straight cut gears
