Take the six bearings (7J627) and coat the inside
bearing surfaces with grease.
Center the rockshaft, with the link ears rearward,
on top of the frame directly above the wheel
arm assemblies as shown in Figure 2a-T. Place
a bearing (7J627) on each end of the rockshaft
above the 10 x 4 frame tube aligning them with the

tube with the inner bearing in the inner most set
of holes. Verify that the rockshaft link ears line
up with the wheel arm link ears. Bolt this bearing
in place with 3/4-10NC x 6” capscrews, lock
washers and nuts. The other bearing should line
up with top bearing used for the rockshaft (3rd
set of holes). Bolt this bearing in place with 3/4-
