4.5.5 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
(B18). Replacing this pin removes some
free movement on the boom and will
improve performance. Figure 20 shows a
link arm, but this is often an aluminum
color.
