TM 5-3895-370-14&PTable 5-4. Direct And General Support Troubleshooting ProceduresMalfunctionTest or inspectionCorrective actionENGINE1. ENGINE FAILS TO CRANK OR CRANKS SLOWLY WITH CLUTCH DISENGAGED.Check crankshaft rotation with hydraulic variable-speed pump removed (para 5-37).If crankshaft rotation is restricted, replace engine (para 5-12).If crankshaft rotation is not restricted, fault not corrected. Notify supervisor.2.ENGINE CRANKS BUT WILL NOT START - NO SMOKE FROM EXHAUST.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 camshaft timing mark alinement (para 5-68).If camshaft is not alined, aline camshaft (para 5-68).If camshaft is alined, replace injection pump (para 5-31).3.ENGINE HARD TO START OR WILL NOT START - SMOKE FROM EXHAUST.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), replace fuel injection pump (para 5-33).5-9
