b. Procedure
Balance tires as follows:
1. Mount the tire and tube (if one is used) on the wheels, but do not install the securing bolts.
Install the wheel bearings in the wheels; then, using the -7 bushings, -6 spacers, and -5 nuts,
install the wheel/tire assembly on the -8 pipe. Secure the -5 nuts finger tight so that the wheel
halves touch each other. Be sure the bolt holes are aligned. Insert the -4 axle through the -8
pipe and place the wheel in the center of the balancer. Make sure the axle is only on the
chamfered edges of the balancer and that it is at 90° to the sides of the balancer.
2. Release the tire. If it is out of balance it will rotate, coming to rest with the heaviest point on
the bottom. Tape an ounce patch across the top center of the tire. Rotate the tire 45° and release
it again. If the tire returns to the same position, add a 1 ounce patch and again rotate the tire
and release it. Continue this procedure until the tire is balanced.
3. When balance is attained, put a chalk mark on the sidewall directly below the patch. Use one
mark for each half ounce of weight needed. Mark the valve stem location on the tire and the
opposite wheel half to assure reassembly in the same position. Remove the wheel from the
balance stand, break it down and clean the inside of the tire with toluol. Apply a coat of patch
cement to both the patch and the inside center of the tire in line with the chalk marks. When
the cement has dried, install the patches making certain they are on the centerline of the tire
and aligned with the chalk marks on the sidewall. Burnish the patches to remove trapped air,
etc.
