1. Lift the chassis off the truck/trailer (Figure 6-1) or rail car using two cranes with a minimum capacity of 50 tons each and place on adequate cribbing in a level position. The weight of the chassis, as shipped, is approxi- mately 133,000 lbs. (60 382 kg) . Cribbing should be approximately 33 in. (84 cm) high at the front, and approximately 12 in. (30 cm) high under the rear axle housing (Figure 6-2). Placement of the chassis at this height will allow easy installation of truck components. Thoroughly clean the chassis.
