Anyone know the gear ratio of a f2400 4wd steer axle? Or how to figure out an open diff ratio? I picked one up for cheap ($50) with the steering cylinder and orbital valve, and want to try an use it for a custom 4x4 project.

Thanks for the reply. Unfortunately that's the front drive axle. I'm looking for the rear/steering axle ratio. I think its a double reduction design, ring and pinion for the input and then again bevel gears at the wheels.

You can ball-park it by marking the output & input shafts and turning the input shaft while counting the revolutions and counting the revolutions of the outputs. Not exact, but we've used it to tell the difference between say a 4:11 ratio, a 4:56 ratio, and a 5:38 ratio.
Yes it is double reduction
Seeing 17and 23 gears which make a 1.76:1 but unsure what the axle side is doing

after about an hour of research, there is actually 3 gear reductions, the input has a gear box, the ring and pinion, and the bevel gears. total reduction is ll.09 to 1. there is two versions of the first stage gear box input/pinon gear shaft, they both use the same bull gear and gear case so one would assume the ratio would be the same.
Thanks for the help y'all. Now I gotta do some math to figure out what rpm hydraulic motor I will need to match the ground speed with the rear drive axle.
