SECTION 2 – SET-UP OF CENTER SECTION
NOTE: Drawing for steps 6 through 9 is on next page.
6. All liftarms will be centered beneath cylinder attach brackets.
– Use 3/4” u-bolts for 4x4 to attach liftarm pivots (8T4100) to frame.
– Slide pivot pin (8T3640) through liftarm and liftarm pivots. All liftarms use the same pivot
pin.
– Insert 7/16 x 3-1/2” bolt in retaining bolt holes. Secure with locknut.
7. Install walking tandem assemblies to bottom of rear liftarms.
– The left hand side of the center frame uses a left hand assembly (8T4166) and the right hand
side uses a right hand assembly (8T4168).
– Slide pivot pin (8T3620) through walking tandem assembly and liftarm.
– Insert 7/16 x 3-1/2” bolt in retaining bolt holes. Secure with locknut.
– Install 8T4190 (left) and 8T4192 (right) mud guards as shown. Secure with 3/8” u-bolts and
flange nuts.
7a. Install walking tandem assembly to bottom of front center lift arm.
– Check inside surface of walking tandem assembly (8T4132). A 3-3/4” diameter surface around
the 1-1/2” dia. pivot hole must be smooth and burr-free. Remove any welding spatter or
roughness prior to further assembly. Install snap rings (8K1920) past grooves of lower pivot
tube. Install V-seals over lower pivot tube until solid side is against snap ring. Protect lip of
V-seals during assembly.
– Install walking tandem assembly to the bottom of center liftarm. Mount so right axle is towards
front. Insert pivot pin (8T3620) through walking tandem assembly and liftarm. Retain
with 7/16” x 3-1/2” bolt and locknut.
– Push V-seals against walking tandem assembly and secure by placing snap ring into
groove.
8. Hang cylinders in the appropriate location.
– Use pins and rollpins provided with cylinders.
– Use 5” x 10” (8T1050) on left hand side of center, 5-1/2 x 10” (8T1055) on right hand side of
center, and 6” x 10” (8T1060) on center wheel assembly.
– The front center lift arm (8T4130) has two cylinder attach locations. If chisel plow will have
a full set of mounted harrows, use rear cylinder attach hole. Cylinder attach location can be
changed based on final adjustments. Connecting front center cylinder to rear hole will lower
front end of chisel plow in transport position.
9. Install 8K1105S (8 bolt) axle and hub assembly into each walking tandem. Apply good quality
anti-seize to axles before installation. Retain axle into receiver tube with 1/2 x 3-3/4” bolt and
locknut.
