Hi guys- can anyone tell me the difference between the Heislers that fit an F12 and an F14?

Thanks

The number of teeth on the input pinion gear and the PTO gear are different. F12 has a 16 tooth pinion gear and 20 tooth PTO. F14 has a 14 tooth pinion and 18 tooth PTO. There is a difference because they slowed the F14 gearing down to match the same standard speeds of the F12.

If you're lookin for a unit and happen to come across one I have copies of an owners manual and contact with a guy who's been through and rebuilt a lot of these units.
