Product Overview
Steering that skips teeth, binds, or leaves too much wheel play often comes from worn gears—and loose bushings can be what destroyed the teeth in the first place. This kit addresses both wear points together.
The three-piece package includes a pinion gear, sector gear, and two steering bushings for compatible Deere 100-series platforms. Serial breaks matter on several D and X models, so verify before ordering.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, dimensions, electrical or mounting configuration, installed options, and previous repairs can affect fitment. Compare the removed part and equipment information before purchase.
Frequently Asked Questions
Q: Why are bushings included with the gears? A: Worn bushings let the shafts move out of mesh, which can accelerate tooth wear on new gears.
Q: Why do some models show a serial limit? A: Deere changed steering parts during production, so later machines can require a different kit.
Q: How do I confirm fitment before ordering? A: Match the original reference number, equipment model and serial number, dimensions, connector or mounting details, and the product photos. Pay close attention to any listed serial breaks.
Q: Is this made by the original equipment manufacturer? A: No. This is a new aftermarket part. Brand names and model numbers are used only to identify compatible equipment.
