8. Remove the elastic locknut (1) and flat washer (2)
holding the retract chain threaded clevis (3) to the
mounting tab on the primary intermediate boom (4).
Save the flat washer and discard the elastic locknut.
9. If a threaded eye or capscrew with flat washer was
installed in step 7, attach a 17 gauge wire to the end
of the retract chain clevis. The wire must be long
enough to pull the clevis and chain through the outer
boom. The wire must be heavy enough, 17 gauge or
heavier, to pull the weight of the entire chain back
through the boom during the reassembly.
If there is no threaded hole on the end of the clevis, a
tow wire and guide wire will need to be attached to
the clevis before pulling the chain out of the boom.
Both wires must be long enough to pull the clevis and
chain through the outer boom. The tow wire must be
heavy enough, 17 gauge or heavier, to pull the weight
of the entire chain back through the boom during the
reassembly. The guide wire is used only to guide the
threaded end of the clevis into the tab on the primary
intermediate boom (4) during reassembly.
Wrap 24 gauge steel wire (5) tightly into the grooves
of the threads of the clevis (6). Start the coils as close
to the tab as possible. Make sure the end (7) has
enough of a tail to wrap into a knot at the top of the
clevis. Push the clevis (6) and guide wire (5) into the
primary intermediate boom (8), so that only the guide
wire is hanging out of the tab.
Loop the tow wire (9), 17 gauge or heavier, over the
top of the tab (10) and back through the hole (11) and
twist the end securely onto the guide wire. This will
allow the tow wire to be pulled back through the
primary intermediate boom (12) along with the guide
wire attached to the chain clevis.
