Assembly
This section covers the proper assembly of the implement. The reference numbers on the
figures give you an indication of the order of assembly. For a complete breakdown of any part not
shown in this assembly section, refer to the parts manual for proper location. Refer to the Appendix
for proper bolt torque values.
Center Frame, Torque Tube & Walking Beam Assembly
After uncrating the machine, place the
center frame (1) Figure 1, in the center of your
work area on stands. Pin the torque tube (2) to
the center frame with the 1¼ x 6 pins (3) and
1¼ x 7 pin (4) in center. Secure them with 3/8 x
2¼ GR 8 hex bolts (5) & lock nuts.
Slide the pivot spindle of the walking
beam assembly (6) into the sleeve at the end of
the torque tube wheel arm. It is a good idea to
put some form of anti-seize on the spindle
before you insert it. Line up the hole in the
spindle with the hole in the sleeve and secure
with 5/16 x 4 hex bolt (7) with lock washer and
hex nut.
When both walking beams have been
installed, bolt on the center transport tires (8),
using 1/2” or 5/8” lug nuts (9). See Section 3
Replacement Parts for proper transport parts
and sizes for your machine model.
