SECTION 2 – SET-UP OF PART 2 WING
NOTE: Drawing for steps 6 through 11 is on next page.
6. Center liftarm under cylinder attach brackets.
– Use 3/4” u-bolts for 4x4 to attach liftarm pivots (8T4100) to frame.
– The pivot closest to the center will be attached with 3/4” x 6-1/2” bolts and a trip assembly.
See page 2-17 Step 2 for further information.
– Slide pivot pin (8T3640) through liftarm and liftarm pivots.
– Insert 7/16” x 3-1/2” bolt in retaining bolt holes. Secure with locknuts.
7. Install wheel spring liftarm support brackets onto bottom of liftarms.
– Use spring support (8T4177) on left wing liftarm. Use 8T4178 on right side. Install 1/2”x7-1/2”
bolts through support bracket and 8T4174 bolt plate. (Third hole towards rear).
– Locate bracket so cross bolts are 3-1/2” above center of pivot pin.
8. Install walking tandem assembly to the bottom of the liftarm.
– The left hand wing will use a right hand assembly – 8T4168.
– The right hand wing will use a left hand assembly – 8T4166.
– 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.
9. Hang cylinders in appropriate location. Use pins and roll pins provided with cylinders.
– Rod end of cylinder (positioned down) attaches to liftarm.
– Use 4” x 10” (8T1040B) on left hand wing.
– Used 3-1/2” x 10” (8T1035) on right hand wing.
10. Insert 8K1100 (6 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.
– Install a right hand wheel spring support (8T4179) onto the front receiver tube on the right hand
walking tandem. Install an 8T4178 on left hand walking tandem. Install an 8T4175 support
on rear tubes of both walking tandems.
– Install 1/2 x 4-1/2” bolts to hold the spring support and axle onto the walking tandems. Secure
with locknut.
11. Install eyebolts and springs between spring supports on each wheel assembly. The spring assist
assembly is designed to keep walking tandem parallel to the bottom of the chisel plow
frame when machine is raised up. This will reduce interference when folding machine into
transport. Adjust lock nut on eyebolts so walking tandem stays in parallel position when wing
is raised. Maximum extended length of spring is 11-3/8”.
