supplies
hydraulic fluid at 40 gallons per minute
(152 liters per minute) to the flow divider
valve  (3),  which  distributes  the  fluid  flow
between the traversing subsystem and the
boom cylinder subsystem. When the tra-
versing subsystem is not being used, un-
used fluid is directed back to the flow
divider manifold for use by the boom cylin-
der
subsystem
as
needed.
The relief valve (7) has two pressure

settings. Only the high pressure setting can
be externally adjusted by the pressure ad-
justment  setscrew.  The  valve  is  normally  in
the  low  pressure  setting  position,  shifting
to  the  high  pressure  setting  when  the
solenoid is energized by the closing of one
of the tow winch level wind switches.

hydraulic fluid at 8 gallons per minute (30
liters per minute) through the filter (12) and
relief valves (8 and 9). The relief valve (8)
allows the hydraulic pressure to build up to
1850  psi  (12,756  kPa)  for  operation  of  the
impact  wrench,  spade,  and  suspension
lockout cylinders. The relief valve (9) is a
solenoid  operated  dual  setting  type
relief
valve. Normally, the relief valve is
deenergized.
