mm) between the cam surface of the number-
two spring hanger and the top of the main leaf
in the unloaded condition. See
Fig. 12

spring hanger (extended-leaf-springs only) for
wear. Excessive wear will reduce the gap avail-

previous note.
6. Place a block of wood on the leaf spring. See
Fig. 13 . Place a pry bar on the block of wood
and insert the end of the pry bar under the frame
hanger. Attempt to lift the frame hanger, as

Fig. 13 . Also, with an empty chassis
