Install plate (18) with bolts (17) and the washers . Tighten bolts (17) to a torque of 425 50 N m (313 37 lb ft).
Use a feeler gauge in order to measure the gap 360° around between plate (18) and the frame.
Remove bolts (17) and the washers. Install the required number of shims (19) that are equal to the shortest distance that was measured in Step 35, minus 0.25 mm (0.010 inch).
Install plate (18), the washers, and bolts (16).
Install the washers and bolts (17) while lower hitch pin (20) is still in the frozen state. Tighten bolts (17) to a torque of 425 50 N m (313 37 lb ft).
After lower hitch pin (20) has reached ambient temperature, tighten bolts (17) to a torque of 900 100 N m (665 74 lb ft). Double torque each bolt (17) with an alternative sequence.
