128-4845     Bolt Assembly    The quality of the joint between the crankshaft and the counterweight depends on the proper amount of bolt stretch of the counterweight bolts. The amount of bolt stretch is determined by the tightening torque that is applied to the bolt. The amount of bolt stretch can be affected by the type of thread lubricant that is used on the bolt. The only acceptable thread lubricant for counterweight bolts is 6V-4876 Lubricant (Molykote). The use of any other type of thread lubricant on the counterweight bolts may result in improper bolt stretch. This could decrease the quality of the joint between the crankshaft and the counterweight. The use of an incorrect thread lubricant could result in damage to the counterweight bolt or the threads in the crankshaft.Procedure For Tightening The Counterweight Bolts In 3508 and 3508B Engines
Prior to assembly, put 6V-4876 Lubricant (Molykote) on the bolt threads, the bolt shank, and the underside of the bolt head. Do not use any other lubricant on the bolt threads.
Tighten the bolts evenly to a torque of 200 5 N m (145 4 lb ft).
Loosen the bolts.
Tighten the bolts evenly to a torque of 70 5 N m (50 4 lb ft).
Put a mark on each bolt head. Tighten each bolt more for 120 5 degrees.Procedure For Tightening The Counterweight Bolts In 3512, 3512B, 3516, and 3516B Engines
