Frequently Asked Questions

What is the difference between the 8N non-adjustable and adjustable steering gearbox parts?

The early 8N used a non-adjustable steering box, while the late 8N built around 1950 to 1952 switched to an adjustable style gearbox. Nut and shaft assemblies differ between the two, so the 8N3575A fits the early non-adjustable box and the 8N3575B fits the adjustable style. Confirm which gearbox your tractor has before ordering.

Which sector gears fit a Ford 9N and 2N?

The 9N and 2N use separate right-hand and left-hand steering sector gears, part numbers 9N3526 and 9N3527. We also carry the matching gearbox shaft, part 9N3525, and the steering column cover assembly for these models. These parts are specific to 9N and 2N and do not interchange with 8N or later boxes.

Do these gearbox parts fit both manual and power steering tractors?

We carry parts for both. There are manual steering nut and shaft assemblies for the 8N, NAA and Jubilee, along with a power steering nut and shaft assembly for the 600, 800, 601, 801, 2000 and 4000. Match the part to your steering type since manual and power components differ.

How do I know which worm shaft or sector arm fits my hundred series tractor?

The NCA3575A manual steering worm shaft fits the 600, 601, 640, 641, 650, 800, 801, 840, 841, 850 and four cylinder 2000 and 4000 models, while the NCA3590A sector arm covers the late adjustable 8N, NAA, Jubilee and hundred series. Fitment can depend on serial number, so match the part number to your gearbox or call (800) 909-7060 for help.
