Ok guys, 77 vette, new pump, valve, cylender, and lines. Adjusting the valve and the nut comes off and dosen't change the rod going in. Also the fluid is geting VERY HOT! Ideas. Thanks guys. Mike

CAUTION. Do not restart engine with
hydraulic cylinder piston rod connected to frame bracket until adjustment
procedure is complete. If out of adjustment, steering wheel may turn causing
injury.
a. Install
new control valve in reverse order of removal. DO NOT RECONNECT THE PISTON ROD
TO THE FRAME BRACKE AT THIS TIME. Torque pitman arm nut to 45 ft-lbs. Torque
valve adapter clamp screw to 20 ft-lbs.
b. Fill
system with new good grade power steering fluid. With power steering reservoir full,
start engine monetarily and shut off refill pump reservoir as required. Repeat until
pump reservoir level remains constant.
a Stan the engine. One of the
following two conditions will exist:
1 If the piston rod remains retracted,
turn the adjusting nut clockwise until the rod begins to move out. Then turn
the nut counterclockwise until the rod just begins to move in. Now turn the nut
clockwise to exactly one-half the rotation needed to change the direction of
the piston rod movement.
2. If the rod extends
upon starting the pump, move the nut counterclockwise until the rod begins to retract,
then clockwise until the rod begins to move out again. Now position the nut to
exactly one-half the rotation needed to change the direction of the piston rod movement.
(CAUTION: Do not turn the nut back and forth more than is absolutely necessary to
balance the valve, as this is a special friction nut.)
3. With the valve
balanced, it should be possible to move the rod in and out manually.
4. Turn off the engine
and connect the cylinder rod to the frame bracket torque to specifications
5. Restart engine. It
the front wheels (vehicle still on the stands) do not turn in either direction
from center, the valve has been property balanced. Correct the valve adjustment
if necessary.
6. When the valve s properly
adjusted, turn off the engine, and install the dust cap.
7. Turn steering wheel to
full left and then to a full right turn and hold momentarily; this bleeds
system.
8. Lower vehicle to floor.
d. Check
for leaks and repair if required. Refill reservoir if oil level den dropped.
FINAL INSPECTION
e.
Check drive belts and readjust tension, if required Replace frayed or glazed
belts at this time. (A high pitched noise at the extreme end of steering wheel travel
indicates a slipping belt)
d. Make
sure diet the hydraulic hoses do not twist or interfere with adjoining hoses or
adjacent chassis parts
