STEERING SYSTEM
74.
STEERING WHEEL DOES NOT TURN SMOOTHLY.
WARNING
Do not attempt to disconnect hydraulic lines and fittings while engine is running or before
hydraulic system pressure has been released. When engine is running, hydraulic system is under
pressure. Hydraulic system pressure should be 0 psi (O kPa) before lines are disconnected. A
line or fitting disconnected under pressure will blow off with great force and can cause injury to
personnel.
Step 1.
Check hydraulic fluid level in reservoir (1) as follows: pull up cap (2) and take out. Wipe off dipstick
(3), put cap (2) on and take out. Check that hydraulic fluid level is between F and L on dipstick (3).
a. Fill reservoir (1) with hydraulic fluid to 4-inches (10.1 mm) below top of filler neck using
6-inch machinist scale. Put cap (2) on and bleed steering system (page 2-1202).
b. If reservoir (1) is full, put cap (2) on reservoir (1) and bleed steering system (page 2-
1202).
c. If reservoir (1) is full and steering system is bled, go to step 2.
Step 2.
Check power steering pump (4) for noise.
a. If reservoir (1) is full and steering system has been bled and noise is heard, notify
Direct Support Maintenance.
b. If no noise is heard, go to step 3.
Step 3.
Pull up and take out cap (2) and check reservoir (1) for air bubbles. If air bubbles are present check
lines, fittings and hoses for loose, cracked or broken condition.
a. If hose (5) is loose, tighten using 1-inch and 3/4-inch open-end wrenches. Fill and
bleed steering system (page 2-1202).
b. If hoses (6 or 7) are loose, tighten using 7/8-inch open-end wrench. Fill and bleed
steering system (page 2-1202).
c. If hose (8) is loose, tighten using 1-inch open-end wrench. Fill and bleed steering
system (page 2-1202).
