Adjustments
24. The hydraulic mechanisms have been factory adjusted
to satisfactorily meet all operating conditions. If it is
necessary to dismantle the equipment, adjustment must be made
at reassembly as the work progresses. When disassembling, it
is desirable to mark all mating parts such as cams, gears,
linkages and adjustable pieces. The adjustments prescribed
in the following paragraphs are given in the order of reassembly.
25. Starting valve adjustment. - The starting valve
must be adjusted before the valve block is mounted on the A-end
case. The adjustment is located at point ITAITas indicated on
figure 37. The clearance required is .005 inch between the
shoulder of .t.he top land of the valve and the valve block
mounting plate as shown on figure 38.
With the valve held against shoulder by spring
271702-11 and with the clevis roller held in the
notch of the starting earn, measure the distance from
the bottom of the clevis to the valve block mounting
face. Adjust the valve to suit. For accuracy
a depth gauge should be used in making the setting.
Best performance of the assembly will be assured if
this setting is maintained.
