Malfunction
Test or inspection
Corrective action
ENGINE
1.
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).
