WT-64 < PERIODIC MAINTENANCE > WHEEL AND TIRE WHEEL AND TIRE Adjustment INFOID:0000000011280544 BALANCING WHEELS (ADHESIVE WEIGHT TYPE) Preparation Before Adjustment Remove inner and outer balance weights from the wheel. Using releasing agent, remove double-faced adhe- sive tape from the wheel and tire. CAUTION: • Be careful not to scratch the wheel and tire during removal. • After removing double-faced adhesive tape, wipe clean all traces of releasing agent from the wheel and tire. Wheel Balance Adjustment CAUTION: • DO NOT use center hole cone-type clamping machines to hold the wheel during tire removal/installa- tion or balancing or damage to the wheel paint, cladding or chrome may result. Use only rim-type or universal lug-type clamping machines to hold the wheel during servicing. • If a balancer machine has an adhesive weight mode setting, select the adhesive weight mode setting and skip Step 2 below. If a balancer machine only has the clip-on (rim flange) weight mode setting, follow Step 2 to calculate the correct size adhesive weight. 1. Set wheel and tire on balancer machine using the center hole as a guide. Start the balancer machine. late the correct size adhesive weight to use. When inner and outer imbalance values are shown on the balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value above and install in to the designated outer position of or at the designated angle in relation to the wheel and tire. a. Indicated imbalance value × 5/3 (1.67) = balance weight to be installed Calculation example: 23 g (0.81 oz) × 5/3 (1.67) = 38.33 g (1.35 oz) ⇒ 40 g (1.41 oz) balance weight (closer to calculated balance weight value) NOTE: Note that balance weight value must be closer to the calculated balance weight value. Example: 37.4 ⇒ 35 g (1.23 oz) 37.5 ⇒ 40 g (1.41 oz) SMA054D |
