SET-UP INSTRUCTIONS FOR RUNNING GEAR
IMPORTANT: Set-up work to be performed by qualified servicemen only.
Mount tires on the wheels and inflate per the tire manufacturer’s recommendations and instructions.
Mount the wheels to the hubs and tighten the hub nuts to 80 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.
Slide the coupling pole into the front and back assemblies, slipping the collar in the back assembly.
Spacing of the coupling pole (approximate distance between holes on the coupling pole) should be 21
1/2”. Distance from center of axle to center of axle is approximately 89”.
Attach the standards (box attachment brackets) to the running gear, unless a rocking bolster is
used.
Fasten the tongue to the front assembly using the tongue bolt (remove paint from the bolt before
attaching) and jam nut. Attach the tongue spring to the bracket on the tongue and hitch assembly.
Check underneath the tongue and make sure that the safety catch (7/8” x 2 1/4” bolt w/spacer) is
secure.
Make sure to properly attach the gravity box (or other equipment) to the running gear. Bolt all four
corners of the gravity box runners to the running gear. (If the box is used in rough terrain and it is not
equipped with a rocking bolster, bolt a minimum of two corners and chain (or cable) the remaining
corners to allow more box flexibility).
