4. Unhook the bail control rod and its spring.
5. Take out the bail-stop-mounting screws.
6. Lift the bail assembly over the escapement operating
levers.
Adjustments
Center bail assemblies, left and right, on the bail stop
brackets. Do this by positioning the two collars on the left
end of the bail-assembly shaft.
Adjust the bails, in relation to the selector bars, as follows:
1. Check shift motion for proper adjustment. Any change
in shift motion adjustment produces a corresponding
change in the position of the bails.
2. Shift the basket to the upper-case position and place
the bail control rod in the expand position. Adjust
the bail-shift-arm-assembly link (Figure 3) so that
the three-unit bail is directly over the rear-most
pointed projection on the selector bars.
3. Shift the basket to the lower-case position and push
the bail control rod in the non-expand position. Adjust
the bail control-rod stop (Figure 3), located on the
key-lever spring-support plate, so that the four-unit
bail is directly over the pointed projection on the front
end of the selector bar for the letter "W."
Maintenance
IRREGULAR SELECTION may occur when:
1. A change in shift motion has been made, changing the
relationship between the selector bars and bails.
2. There is a loose bail control-rod stop.
3. There is a bind between the bail assembly and a
Westinghouse motor.
LUBRICATION. Oil all links, clevises and the pivot points
of the bail assembly.
SELECTION - ESCAPEMENT OPERATING-LEVER
ASSEMBLIES
These levers, through their links, transmit the motion
from the bails to the latches on the escapement-pawl carriers.
Removal
Refer to the section entitled "Selection Mechanism-
Selector Bars."
Adjustment
ESCAPEMENT OPERATING-LEVER COLLARS are located on
both sides of the escapement operating levers and should
be positioned so that there are no binds between the levers
and the rear selector-bar guide comb.
