SET-UP INSTRUCTIONS
IMPORTANT: Set-up work to be performed by qualified servicemen only.
1. Mount tires on the wheels and inflate to 80 psi.
2. Mount the tires to the hubs and tighten the flat hub nuts to 500 ft. lb. torque. Check the hub nuts after
the first hour of operation, then every 10 hours of operation for the first 40 hours of use. These nuts must
be kept tight at all times. Wheels that are improperly installed on the running gear, resulting in product
failure, will nullify the warranty and shift the burden of liability to the owner/operator of the equipment.
3. Slide the coupling pole through the rear A-Frame, inserting the collar to coupling pole and through the
front A-Frame. When mounting to a 680SD or 760SD Gravity Wagon, the distance from the center of
axle to center of axle is approximately 134”.
4. Fasten the tongue to the front of the assembly using the tongue bolt (remove paint from the bolt before
attaching) and the hex nut. Attach the tongue springs to the brackets on the tongue and hitch assembly.
5. Mount the brakes lines from the rear of the master cylinder to the Drum Brakes according to the
Tongue Assembly and Brake Lines and Fittings drawing located in the Repair Parts Section of this
manual. Be careful not to over tighten the fittings and strip the threads. Use care in shaping brake lines
to avoid sharp bends or kinks. Be sure to use a “Double-Flaring” type of tool on steel tubing to assure
tight leak proof connections. Be sure and use hydraulic rubber hoses at points of flexing. Anchor hose
ends to avoid stress on tubing. Always use DOT 5 Silicone Brake Fluid or equivalent.
