Check the beam deformation by attaching a try square to the
outer (fig. 3-56) and side (fig. 3-57) surfaces of the flange
A.70172; if the beam is not deformed, the try square will fit per-
fectly.
Size of deformation is checked by a probe. If a 0.2 mm gauge
passes through on any of the flanges, the beam should be
straightened.
Using a try square (fig. 3-58), check the normality of the
reduction gear fastening surface vs the seating surface of flange
A.70172. The 0.2 mm feeler gauge should not fit.
Make a 90 ° turn of the axle beam and place it on V-blocks.
A try square applied to the outer surface of the flange (fig. 3-59)
should adjoin with no gaps, otherwise check the size of deforma-
tion by a feeler gauge. The 0.2 mm gauge should not fit.
