BBC / BOS / BCS
e. Traction Lever: provides input to the traction cable
since the end of the traction cable is retained in it.
It also pivots on the upper shoulder bolt when the
control bar is moved.
These components interact to provide control to the BBC
deck mechanism. Notice in Figure 183 the position of
the traction cable lever and the BBC cable lever. This is
the “at rest” position; both the BBC and the transmission
are disengaged. When the control bar is in this position,
it is the buckling spring that supports it. Notice that the
buckling spring is not flexed and is at the left end of the
slot in the rocker arm.
f. Rocker Arm: pivots on the upper carriage bolt. It is
affixed solidly to the control arm by means of the roll
pin. It houses both the control hook and cable lever.
It also provides slot and stop for the buckling spring.
g. BBC Cable Lever: controls tensioning and loosening
of the BBC cable since the end of the BBC cable
is retained by it. Pivots freely on the upper carriage
bolt. Movement is controlled by the control hook.

D
h. Control Hook and Spring: pivots on the roll pin and
is spring-loaded in the counterclockwise direction by
the torsion spring. The control hook “grabs” the cable
lever when the control bar is cocked and releases
the cable lever when the control bar is dropped.
B
i.
Buckling Spring: sole purpose is to hold the control
bar in the middle position when at rest. The spring is
flexed or “buckled” when the control bar is operated.
It rides in a slot on the rocker arm to prevent it from
applying force to the control bar when the control bar
is at its lowest or uppermost positions.

j.
Right Control Housing: serves as the other half of
the control box cover. Houses the leaf spring.
k.
Leaf Spring: releases the control hook as the
control bar drops to “at rest” position. Because of its
orientation, it allows the control hook to slip by as the
control bar is raised.
