TM 5-3895-370-14&PTable 5-4. Direct And General Support Troubleshooting Procedures - CONT.MalfunctionTest or inspectionCorrective actionENGINE (CONT)7.ENGINE RUNS ROUGH AND MISFIRES.Step 1. Remove and test injectors (para 5-30).If injectors do not open at 3160 to 3307 psi (21788 - 22802 kPa), replace injectors.If injectors open at 3160 to 3307 psi (21788 - 22802 kPa), go to step 2.Step 2. Check engine compression on each cylinder.If compression for each cylinder is not 350 psi (2413 kPa), replace piston rings or pistons(para 5-67) or cylinder sleeves (para 5-63).If compression for each cylinder is 350 psi (2413 kPa), go to step 3.Step 3. Check camshaft alinement (para 5-68).If camshaft is not alined, aline camshaft.If camshaft is alined, replace fuel injection pump (para 5-33).8.ENGINE FAILS TO DEVELOP FULL POWER.Step 1. Check engine rpm with hydraulic variable-speed pump removed (para 5-37).If engine does not reach full power, go to step 2.If engine reaches full power, replace hydraulic variable-speed pump (para 5-37).Step 2. Remove and test injectors (para 5-30).If injectors do not open at 3160 to 3307 psi (21788 - 22802 kPa), replace injectors.If injectors open at 3160 to 3307 psi (21788 - 22802 kPa), go to step 3.Step 3. Check engine compression on each cylinder.If compression for each cylinder is not 350 psi (2413 kPa), replace piston rings or pistons(para 5-67) or cylinder sleeves (para 5-63).If compression for each cylinder is 350 psi (2413 kPa), replace fuel injection pump (para 5-31).5-11
