Step 5.
Remove power steering gear (para 3-28d).
Remove valve assembly from power steering gear (para 3-28d).
Check if valve spool is sticking in valve assembly.
a. If valve spool is sticking in valve assembly, clean valve spool
and inspect it for burrs, wear or damage (para 3-28d). Replace
valve assembly (para 3-28d) if spool is burred, worn, or
damaged. If spool is not burred, worn, or damaged, reinstall in
valve assembly (para 3-28d) and recheck for sticking. Replace
valve assembly if necessary (para 3-28d).
b. If valve spool is not sticking in valve assembly, notify general support maintenance.
7. HIGH STEERING EFFORT IN ONE DIRECTION
Step 1.
Remove power steering reservoir dipstick (para 2-58c).
Attach a vacuum pump to power steering reservoir fill opening.
Operate pump several minutes to create a vacuum inside the reservoir.
NOTE
If you do not draw enough air out of the power steering reservoir, hydraulic oil will gush out of hose when
performing the following procedure (some loss of oil is normal).
With vacuum pump operating, disconnect power steering pump main supply hose at power steering pump (para 2-
58b).
Connect 10 GPM flowmeter inlet hose to power steering pump.
Connect flowmeter outlet hose to main supply hose disconnected from power steering pump.
Turn off vacuum pump and disconnect from power steering reservoir.
Set flowmeter volume control for 10 US GPM and open flowmeter load valve.
Check power steering reservoir oil level; add oil if level is low (para 2-58c).
Start vehicle engine and operate at 1200 RPM.Close flowmeter load valve until flowmeter pressure gage indicates
100 psi.
Flowmeter volume reading should be 4.0 GPM.
a.
If flowmeter volume reading is not 4.0 GPM, remove and repair power steering pump (para 3-28f).
