This fork bushing is a sleeve that fits into the front axle assembly of the host tractor. It provides a bearing surface for the steering linkage fork, allowing the fork to pivot smoothly under load. Wear on the bushing bore introduces play in the steering linkage, which causes imprecise wheel tracking and accelerated wear on the adjacent pivot pins. The part is machined to the same internal diameter and wall thickness as the original sleeve, so it seats in the axle housing without shimming. On installation, ensure the bore is clean and free of debris before pressing the bushing into place.
