Step 1: Pulled the bearings from the U 51-201 GROVE 5.00 X 5 Wheels & Brakes wheel assemblies by removing the snap-rings retaining them. Paid close attention to how the bearings, washers, and grease seal felts are installed so they may be reinstalled the same way. See Figure 1.
Step 2: Split the main wheel assembly by removing the bolts holding the brake disc and the inner and outer wheel halves together as shown in Figure 2.
Step 3: Dusted the U 5:00X5-6IT Inner Tube and the inside of the U-5:00X5-6 Tire with talcum powder. Lubricated the valve stem with a small amount of grease prior to pushing it through the grommet. Mounted the tube and tire on the inner and outer wheel halves while aligning the red dot on the tire next to the valve stem of the tube. See Figure 1. Bolted the wheel halves and the brake disc together carefully, observing the manufacturer's bolt torque specifications shown on the document in the wheel and brake package. Checked that the tube is not pinched between the wheel halves.
Step 4: Slowly inflated the tire to 25 psi. Deflated fully and re- inflated slowly a couple more times to work out any wrinkles in the tube.
Step 5: Reinstalled the valve stem core as required and slowly inflated the tube/tire to a final pressure of 28 psi (193 kPa).
Step 6: Checked the valve stem for air leaks and check the tire for proper seating around the wheel rim.
Step 7: Cleaned, dried, and fully greased the bearings from the Main Wheel & Tire Assembly using AeroShell Grease 22.
Step 8: Reinstalled the bearings, washers, and grease seal felts in the same order they were removed. See Figure 1.
