TM 5-3805-262-342-13. STEERING SYSTEM TROUBLESHOOTINGMALFUNCTIONTEST OR INSPECTIONCORRECTIVE ACTION1. NO RESPONSE WHEN STEERING WHEEL TURNED.Step 1.Perform hydraulic pump steering section test no. 1 (page 3-500).a.b.c.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 hydraulicfilters and hoses, lines, and fittings are okay, hydraulic pumpis 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 betweenhydraulic 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 isabove 75 percent, go to step 2 below.Step 2.Perform steering circuit anda. If pressure readings areflow control valve (pageb.If pressure readings arerelief valve test no. 2 (page 3-505).not as specified in test no. 2, replace3-566) .okay, remove(page 3-510) and go to step 3 below.Step 3.Disassemble steering gear(page 3-512).Inspect rotor and statorfor-cracks, distortion, ordamage.Put rotor in stator. Usethickness gage to measureclearance between rotor andstator as shown.Clearance must not exceed0.005 inch.and replace steering geara. If clearance between rotor and stator exceeds 0.005 inch, re-place rotor and stator (page 3-518); replace rotor or stator ifcracked, distorted, or damaged (page 3-518).b. If rotor and stator check okay, go to step 4 below.2-113
