assembled, adjusted and lubricated before use. Illustrations to assist with the assembly process are provided in “Standard Specifications” on page 2-1. They show proper disc gang, wing stabilizer bracket, and light mounting bracket spacing. Illustrations in this section show proper assembly procedures. Remove paint from grease fittings. Replace any grease fittings that are damaged or missing. Be sure to return screws, clips, etc., to their original locations.

To insure alignment of assemblies, leave the nuts loose until completion of final assembly. Use lock washers or flat washers as specified. Spread all cotter pins.

After completion of final assembly, tighten all nuts evenly to prevent misalignment, distortion or binding.

Tighten all screws and nut s to the recommende d torques

(See “General Torque Specifications” on page 2-4.).

Be sure to bleed the hydraulic system of all air in lines after inst allation. Failure to bleed the syst em of all air can result in improper machine operation.

Assembly Instructions

Disc blades are extremely sharp. Exercise extreme care when working on or near disc blades. Do not allow discs to roll over or fall on to any bodily part. Do not allow wrenches to slip when working near disc blades. Never push wrenches toward disc blades. Do not climb over machine above disc blades. Fail ure to stay clear of disc blade edges can cause serious personal injury or death.

Do not attempt to lift heavy parts (such as the frame, disc gangs, rock shaft, and pull hitch) manually. Use a hoist or a fork lift to move these parts into position.

To prevent accidental lowering:

1. All hydraulically elevated equipment must be locked out using the cylinder lockouts:

2. Lower equipment to the ground while servicing or when it is idle.

Failure to take measures to prevent accidental lowering may result in serious personal injury or death.

Disc Gangs

Disc blades are extremely sharp. Exercise extreme care when working on or near disc blades. Do not allow discs to roll over or fall o nto any bodily part. Do not allow wrenches to slip when working near disc blades. Neve r pus h wrenches toward disc blades. Do not climb over machine above disc blades. Failure to stay clear of disc blade edges can cause serious personal injury or death.

1. Attach the disc gang assemblies to the center section using 3/4-10 x 2-1/4, 3/4-10 x 8, 3/4-10 x 9 grade 8 hex head cap screws, and hex lock nuts (See Figure 3-1.) Use a 3/4-10 x 9 grade 8 hex head c ap screw, manifold mounting bracket, and hex lock nut on the center front screw of the left rear gang for all sizes.

2. Install a 1/2 x 2-1/4 grooved alloy pin in the end of each hinge pin.

3. Assemble each wing gang to the center frame gang using the hinge pin, 1-3/4 thrust washer, and 1-1/4-7 hex lock nut allowing the blades to sit on the ground.

4. Assemble rh/lh light brackets.

The thrust washer is positioned on the rear side of the inner hinge on the front gangs, and on the front side of the inner hinge on the rear gangs.

Mounting Center Frame Tires and Wheels

Install the tire and wheel assemblies on the center section. The center frame tires uses 235/75R17.5 tIres with 8-bolt walking dual wheels and 4” slip-in spindles.

1. Make sure that all mounting surfaces are clean and free of rust, dirt or paint. A wire brush may be used to clean these surfaces (See Figure 3-1.)

2. Position the inner disc wheel over the studs, being careful not to damage the stud threads. Make sure that the disc wheel is flat against the mounting surface. There will be a wheel spacer on the hub and it needs to be mounted between the hub and the inner wheel.

Do NOT put wheel spacer between the wheels.

3. Position the outer disc wheel being careful not to damage the stud threads. Be sure the valve stems for both the inner and outer tire are pointing away from each other (facing outward). Align wheel holes when mounting.

4. Install the flange nut and tighten to 50 foot-pounds using the sequence in Figure 3-2. Then tighten to full torque of 450-500 ft./lbs.

5. Torque will drop after the first 10 hours of operation. Check the nuts for proper torque after this interval and retighten them.

Use a torque wrench to assure proper torque. Insufficient torque can cause stud breakage and damage wheel pilots. Overtorque can overstress the studs and strip the threads.

Figure 3-2: Stud Tightening Sequence

All tire/wheel assemblies are mounted with the valve stem facing outward.
