Claim:
Rockshaft bearing block structure for rotatably mounting a portion of a rockshaft for an implement frame, the rockshaft having a rotational axis, a circular cross-section and a rockshaft thrust surface extending radially outwardly of the circular cross-section, the bearing block structure comprising: first and second bearing block sections, the sections including first and second arc-shaped cavities; first and second arc-shaped bearing block inserts received in the respective first and second arc-shaped cavities, the inserts rotatable mounting the rockshaft for rotation about a rockshaft axis, the inserts bearing against the circular cross section; wherein the bearing block inserts include a thrust flange extending axially outwardly of the bearing block sections and radially outwardly of the circular cross section; connector structure releasably securing the first and second bearing block sections and the inserts around the rockshaft with the thrust flange located between the thrust surface and the bearing block sections, the rockshaft thrust surface bearing against the thrust flange to limit axial movement of the rockshaft relative to the bearing block sections, the first and second bearing block sections releasable to remove the inserts from around the rockshaft without need to remove the rockshaft from the implement frame; and wherein the rockshaft connector structure includes a bolt-receiving bore portion, and the inserts include a notch received against the bolt-receiving bore portion.
