Set Up Instructions
IMPORTANT: Set-up work must be preformed by qualified servicemen only.
•
Mount tires on the wheels and inflate the 325/65 R22.5 tires to 75 PSI or for 385/65 R22.5 tires the correct pressure is 70 PSI.
•
Mount the wheels to the hubs and tighten the flat hub nuts to 190 ft. lb. torque.
NOTE: 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. The distance between the
holes of the Front and Rear Running Gears should be approximately 24”. (Figure 1)
•
Insert (2) 3/4” x 6” hex bolts and 3/4” center lock nuts in to the Coupling Pole.
NOTE: Do not over tighten the Bolts. You should still be able to spin the bolts when tightened.
•
Fasten the tongue to the front of the assembly using a 1-1/4” x 9-1/2” King Pin, (2) 1-1/4” Hex Nuts and a 1-1/4” Flat Washer. (Figure 2)
Note: Make sure that the King Pin is inserted so the square top of the King Pin rest against the Flat Bolt Keeper.
