9.
ENGINE EXHAUST SMOKES EXCESSIVELY.
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 engine.
If compression for each cylinder is 350 psi (2413 kPa), replace injection pump (para 5-31).
10.
ENGINE OPERATING TEMPERATURE TOO HIGH.
Step 1. 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 2.
Step 2. Check engine temperature with hydraulic variable-speed pump removed (para 5-37).
If engine does not operate at normal temperature, replace injection pump (para 5-33).
If engine does operate at normal temperature, replace hydraulic variable-speed pump (para 5-
37).
11.
ENGINE LOSING COOLANT.
Step 1. 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 2.
