It is important to keep the same size tires on each side of the loader. If different sizes are used, each tire will be turning at a different rate and cause excessive wear. The tread bars of all the tires must face the same direction.
TIRE MAINTENANCE Wheel Nuts Figure 10-170-1
Recommended tire pressure must be maintained to avoid excessive tire wear and loss of stability and handling capability. Check for the correct pressure before operating the loader. Mounting Tires are to be repaired only by an authorized person using the proper procedures and safety equipment. Tires and rims must always be checked for correct size before mounting. Check rim and tire bead for damage. The rim flange must be cleaned and free of rust. P-54291
(See SERVICE SCHEDULE on Page 10-70-1),for the service interval to check the wheel nuts [Figure 10-1701]. When installing wheel nuts, tighten to 160 ft.-lb. (217 N•m) torque.
The tire bead and rim flange must be lubricated with a rubber lubricant before mounting the tire. Avoid excessive pressure which can rupture the tire and cause serious injury or death. During inflation of the tire, check the tire pressure frequently to avoid over inflation.
When checking wheel nut torque, set the torque wrench to 140 ft.-lb. (190 N•m) torque to prevent over-tightening.
IMPORTANT
Rotating Figure 10-170-2
Inflate tires to the MAXIMUM pressure shown on the sidewall of the tire. DO NOT mix brands of tires used on the same loader. I-2057-0794
WARNING Do not inflate tires above specified pressure. Failure to use correct tire mounting procedure can cause an explosion which can result in injury or death. W-2078-1285 B-9976
Check the tires regularly for wear, damage and pressure. (See Tires on Page SPEC-10-4.), for the correct tire pressure. Rear tires usually wear faster than front tires. To keep tire wear even, move the front tires to the rear and rear tires to the front [Figure 10-170-2]. 10-170-1
