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).
