TM  10-3930-638-24&P 2-46.   STEERING   SYSTEM   TROUBLESHOOTING   (cont) MALFUNCTION TEST OR 1. VEHICLE WILL INSPECTION CORRECTIVE  ACTION NOT TURN WHEN STEERING WHEEL IS TURNED (cont) Step 5. Check setting of relief valve (para 2-48b (2), step 22). a. If pressure indication is not 2500-2550 PSI. adjust relief valve (para 2-48b (2). step 23). b. If pressure indication is 2500-2550 PSI, replace steering gear (notify direct support maintenance). 2.  VEHICLE  TURNS  CORRECTLY  IN  ONE  DIRECTION  BUT  NOT  IN  OTHER  DIRECTION Step  1. Check hoses, lines and fittings between steering gear and steering cylinders for oil leaks (para 2-48b). a. If oil leaks are observed, tighten fittings or replace hoses (para 2-48b). b. If oil leaks are not observed, proceed to step 2. Step 2. Check steering cylinders for oil leaks at rod end. a. If oil leaks are observed, replace steering cylinder. b. If oil leaks are not observed, proceed to step 3. Step 3. Check steering gear for oil leaks at fittings. a. If oil leaks are observed, tighten fittings. b. If oil leaks are not observed, proceed to step 4. Step 4. Rotate steering wheel until vehicle is fully turned (articulated) to the left. With engine off, loosen two clamps and slide cylinder guard toward front of vehicle, and disconnect hose from elbow as shown. WARNING Keep hands and feet clear of steering cylinder assembly while checking for leakage. Failure to do so may cause serious injury. Start engine and hold steering wheel at the full left turn position. Check for hydraulic oil leakage from the open steering cylinder elbow, then stop engine. a. Hydraulic oil coming from open steering cylinder elbow  indicates  internal  steering  cylinder  leakage. Replace  steering  cylinder  assembly  (para  2-48c). b. If hydraulic oil does not leak from open steering cylinder  elbow,  reconnect  hose  to  elbow,  reinstall clamps and cylinder guard and proceed to step 5. 2-322
