2-13. STEERING SYSTEM TROUBLESHOOTING
TEST OR INSPECTION
1. NO RESPONSE WHEN STEERING WHEEL TURNED.
Perform hydraulic pump steering section test no. 1 (page 3-500).
If flow recorded in above test is less than 23 gallons per mi-
nute, check hydraulic filters and hoses, lines, and fittings be-
tween hydraulic pump and reservoir for an air leak. If hydraulic
filters and hoses, lines, and fittings are okay, hydraulic pump
is worn; remove and replace hydraulic pump (page 3-612).
If flow recorded in above test is more than 23 gallons per mi-
nute, hydraulic filters and hoses, lines, and fittings between
hydraulic pump and reservoir are okay.
If efficiency determined in above test is below 75 percent, re-
move and replace hydraulic pump (page 3-612). If efficiency is
above 75 percent, go to step 2 below.
Perform steering circuit and
a. If pressure readings are
flow control valve (page
If pressure readings are
relief valve test no. 2 (page 3-505).
not as specified in test no. 2, replace
(page 3-510) and go to step 3 below.
Disassemble steering gear
Inspect rotor and stator
for-cracks, distortion, or
Put rotor in stator. Use
thickness gage to measure
clearance between rotor and
stator as shown.
Clearance must not exceed
and replace steering gear
a. If clearance between rotor and stator exceeds 0.005 inch, re-
place rotor and stator (page 3-518); replace rotor or stator if
cracked, distorted, or damaged (page 3-518).
b. If rotor and stator check okay, go to step 4 below.
