7.4 Link Arm Pin Replacement

The John Deere link arm located between the black tee frame and the boom must have the top
pin replaced. Remove the Top pin from the arm and insert the supplied pin (P04). Replacing

this pin removes some free movement on the boom and will improve performance. Figure 17
shows a link arm, but this is often an aluminum color. The bottom bolt must be tightened to
266 ft-lbs (350 Nm).
