16. Assemble linkage as shown in photos and clamp leveling valve bracket to
frame crossmember in location shown so that linkage geometry matches photo.
Make sure leveling valve is as close to crossmember as possible to provide axle

time. Center leveling valve by inserting a 11/64” drill bit through hole in arm and
body of leveling valve. When satisfied with linkage geometry, REMOVE drill
bit.
