the backing plate with a heavy screwdriver.
Rotate them into place against the anchor
pin.
18. Install the anchor pin plate (4-2).
19. Install the shoe return springs (4-1) using a
brake spring tool
20. Move the magnet lever arm along its track
to ensure that the shoes expand and con-
tract properly and are in the correct adjust-
ment. When making this test, the shoes
can stick in their expanded position. To
correct this, merely push the shoe back
into position. Once the shoe drum has
been installed, the shoe will be restricted
from expanding far enough to stick.
21. Reassemble the drums and wheel and
make sure the wheel bearings and wheel
nuts are adjusted to the axle manufactur-
er’s specifications.
