(c) 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.
(d) When reassembling the wheel, powder the inside of the tire. Mount the tire on the valve
side of the wheel in the same position it was in when it was balanced. Install the other
wheel half, aligning the chalk marks. Install the bolts and tighten to required torque, then
inflate the tire to the pressure specified in Table II-I, and recheck the balance. The wheel
should not be more than one ounce out of balance.
