ADJUSTMENTS
47. The hoist assemblies have provision for adjusting
the controls, indicators, brake and operating pressures as
described in the following paragraphs and references.
48. Indicator mechanism and upper end control adjustment.
The adjustment of the indicator rope and rods to eliminate slack
in the indica tor mechanism is vi tal inasmuch as slack in the
assemblage will not gi ve posi ti ve control gear interlock. The
correct action of both the !'HOISTl'indicator and the !!LOWER!!
indicator is obtained if the respective ropes are adjusted so
that the signs at the control stations move to signal as described
in paragraph 39. The hoist latch, the latch release
and the safety stop will then have intended actions. These
ropes can be adjusted to remove s.lack at cable adjustments that
are located on the hoist and are accessible in the pan floor
level (see sk. no. 88878). The positions of the indicators at
the lower station are fixed with respect to the upper station
and are not adjustable.
Whenmaking adjustment of the "HOIST" indicator rope
the parts should be adjusted with a proj eetile in
the cradle (cradle folded). This will displace the
proj ectile indica tor lever to the posi tion tha t should
synchronize with "DANGER!! at the control stations.
Adjust the indicator rope to center !!DAlIJGER" in the
windows. Adjust the indicator retainer, 216369-3,
so that it is in position to ride the earn arc on the
cradle. This adjustment can be made by repositioning
the connecting rod that is between the retainer
and the rope yoke or by re-setting adjusting rod
216368-5.
Whenmaking adjustment of the direction control indica
tor, place the direction control at "1mlERPRO-
JECTILES" and position the sign !!10\.JER"in the windows.
Adjust the cable clamp to remove slack.
49. Cradle operating cylinder piston adjustment. - Refer
figure 44. The cradle operating piston must be coupled
to the cradle so that the piston will not "bottom" or cover
the starting port. The piston is in correct position when
dimension "XII, figure 44, equals the following (approx.):-
Outboard hoist, "X" 1. 5 ins.
center hoist, lIX" = 2.135 ins.
