24, PRIORITY FLOW CONTROL
VALVE. A priority flow control valve is
used on all models except 2110 to ensure
an adequate supply of oil is available to
the power steering. The control valve
divides the oil flow from hydraulic sys-
tem pump to provide priority oil flow to
power steering and directs remaining oil
flow to tractor hydraulic system.

valve used on 1700 and 1900 models with power
steering. Refer to Fig. 43 for legend except for
shim (7).
On 1700 and 1900 models the priority
valve is mounted on the right-hand side
of the hydraulic hitch housing. On 1310
and 1910 models, the priority valve is at-
tached to right-hand side frame rail. On
1510 and 1710 models, the valve is at-
tached to left-hand side frame rail.
Refer to appropriate Fig. 43 or 44 for
an exploded view of priority flow control
valve. When servicing the valve, be sure

cessively worn or damaged. Light
