Place third mark 21½ in. ± 1/32 in. (64.6 cm ± 0.8 mm) rearward of center mark.
Position each straightedge (1) against hub face (2) of front axle. Straightedge must be parallel to ground with its
center mark placed at axle centerline.
Measure and record distance between two rear marks of each straightedge (1). This is dimension A of
illustration.
Measure and record distance between two forward marks of each straightedge (1). Distance between two
forward marks should be 5/16 in. ± 1/16 in. (7.9 mm ± 1.6 mm) LESS than dimension A. This is dimension
A - 5/16 in. of illustration.
NOTE
During adjustment, ensure that distances from each straightedge to centerline of front
drawbar are equal, as indicated on illustration.
If distance between two forward marks of straightedge (1) is out of tolerance, adjustment must be made in
