Problem
New washers need to be installed on the bolts that hold the counterweight to the crankshaft in certain 777B and 789 Trucks; and 3508, 3512, and 3516 Engines. The new washers have a smaller outside diameter to prevent the washer from contacting the chamfer in the counterbore of the counterweight.
