Put a pry bar between the bolts andagainst the frame so the crankshaft will notturn while bolt (2) is tightened to the correcttorque.Tighten bolt (2) to a torque of 312 ± 27 N·m(230 ± 20 lb. ft.). Hit the bolt with a hammer.Tighten the bolt again to a torque of 312 ± 27N·m (231 ± 20 lb.ft.).Install vee belt (4) on the air conditionercompressor and the crankshaft pulley (if soequipped).Use tool (A) to measure the belt tension. Ad-just the belt tension until the gauge reading fora new belt is 534 ± 22 N (120 ± 5 lb.). Adjustthe belt tension until the gauge reading for aused belt is 400 ± 44 N (90 ± 10 lb.). A usedbelt is one which has more than 30 minutes ofoperation at rated engine speed. When the belttension is correct, tighten all the bolts and nutsin the mounting bracket.5-58
