Springs, Bogie Assembly and
Rolling Test
Cut eight lengths of the primary spring wire, each 32mm long.
Degrease the wires and apply, to one
end of each wire, a bead of fast setting
epoxy resin about 1mm diameter, i.e. just
large enough to prevent the springs being
pulled through the holes in the ears of the
central bearing carriers. Put the springs to
one side while the resin sets.
Cut eight lengths of the secondary
spring wire, each 24mm long. Make a
bend in each wire, 8mm from one end, of
just slightly less than 90°. Fold up the four
spring retaining ears on the corners of each
bolster. Pass the longer arms of the wires
through the holes in the secondary spring
seats...
...and clip the shorter arms into the
spring retaining ears. Put the bolsters
safely to one side.
Return to the primary suspension wires and check that the epoxy resin beads have
set hard.
