ADJUSTMENT 1. Loosen two screws (Figure 4, Item 5) on idler pulley assembly (Figure 4, Item 7). 2. Pry upward on tang of idler pulley assembly (Figure 4, Item 7) to get 1/4 to 3/8 inch (6.4 to 9.5 mm) deflection on drive belts (Figure 4, Item 6) midway between pulleys (Figure 4, Items 15 and 16) while applying a firm push with thumb. Tighten two screws (Figure 4, Item 5). 3. Check for proper tension by using straight edge (Figure 4, Item 17) to measure deflection across drive belts at pulleys (Figure 4, Items 15 and 16). If dial indicator tensionmeter is available, check for 40–50 lbs (173–217 N·m) tension. If necessary, readjust tension, and then torque two screws to 30–35 lb-ft (41–47 N·m). 5 17 15 16 6 7 1/4 TO 3/8 in. (6.4 TO 9.5 mm) MAINT_030 Figure 4. Coolant Pump Drive Belt Adjustment.
