Frequently Asked Questions

Which transmission input drive shaft fits a Ford 8N or a Ford 801 tractor?

The two series use different input drive shafts. Broken Tractor offers SKU 2N7017A for the 9N, 2N, 8N, NAA, 500, 600, 700, 800 and 900, and SKU 311203 for the 4-speed 601, 701, 801, 901 and four-cylinder 2000 and 4000. We also carry the matching input shaft tube, SKU 311202, for the 601, 701, 801, 901 and four-cylinder 2000 and 4000. Confirm your model before ordering, because input shafts and tubes vary by series.

Will Ford 4-speed transmission gears fit a Select-O-Speed tractor?

No, the main shaft and countershaft gears we carry are made only for the 4-speed gearbox and do not fit Select-O-Speed transmissions. For example, the main shaft second gear (SKU B9NN7A381B) fits 4-speed 8N, NAA, 600 through 900 series, 2000, 3000 and 4000 tractors. Check that your tractor has the 4-speed before ordering.

What PTO shaft assembly fits a Ford 9N, 2N or 8N tractor?

Broken Tractor carries the 1-3/8 inch 6-spline PTO shaft assembly (SKU 9N700-38), the PTO shaft assembly SKU 9N700-18, and a PTO shaft conversion kit (SKU FD07-F002), all listed for the 9N, 2N and 8N. Ford NAA and Jubilee owners have a separate option, the 1-3/8 inch PTO shaft assembly SKU NAA700-38, which includes the shaft, housing and bearings.

Which transmission countershaft fits my Ford NAA, 8N or 800 series tractor?

The countershaft depends on the model. SKU 8N7111 fits the 8N, SKU NAA7111C fits the NAA and Jubilee, and SKU NDA7111C fits the 600, 601, 800, 801, 900, 901, 2000, 3000, 3400 and 3500. If you are unsure which one your tractor uses, match the SKU to your model or call (800) 909-7060 to confirm with the parts team.

What PTO coupler and PTO stop fit a four-cylinder Ford 600, 800, 2000 or 4000?

The PTO coupler SKU NCA717A fits 600 series, 800 series and four-cylinder 2000 and 4000 tractors. The PTO stop SKU NAA722A fits the NAA, Jubilee, 600, 800 and four-cylinder 2000 and 4000. We also offer a PTO countershaft and coupler kit, SKU FD07-G001, listed for the 600, 601, 700, 701, 800, 801, 900, 901 and four-cylinder 2000 and 4000.
