I bought an f12 in 1993 that was advertised as an f14. The serial number on the tag and the block serial number indicated it was a 1937 f12 but it had all the attributes of an f14: steering post, oil breather, head and transmission changes. I bought an overdrive for an f12 and it would not fit. The bevel transfer gear for the true f12 had a larger OD than the f14 with a different pitch diameter and a different number of teeth. The fewer teeth on the smaller f14 transfer gear mated with the larger gear it matched up with would give the tractor a slower speed. The r.p.m. of the motor was speeded up to give more horse power at the same speed. Good luck on finding the proper overdrive. I saw one at Kings tractor auction that went really high. Dal Wolf
