11 and 13 Shank Walking Beam
Position the wheel arm assemblies under the
frame as shown in Figure 2a-T2 and 2b-T2. Note
that the inner wheel hubs are forward of the machine
and the longer end of wheel arm pivot tubes is
outward.
Take the six bearings (7J627) and coat the inside
bearing surfaces with grease.
Place one 7J627 bearing per wheel arm on
each end of wheel arm pivot tube. Position the
assembly under the 10 x 4 frame tube with the
outer bearing in the outer most set of holes. The
other bearing should line up with the 3rd set of
holes. Bolt them in place with 3/4-10NC x 6”
capscrews, lock washers and nuts. (Hardware
is in box 7J857 for 11 shank machines and box
7J858 for 13 shank machines)
Center the rockshaft, with the link ears rearward,
on top of the frame directly above the wheel
arm assemblies as shown in Figure 2b. Using
the same type of bearings (7J627) as the wheel
arms, position them on each end of the rockshaft
above the 10 x 4 frame tube aligning them with the
appropriate set of holes. Verify that the rockshaft
link ears line up with the wheel arm link ears. Bolt
them in place with 3/4-10NC x 6” capscrews, lock
washers and nuts.
