TM 10-3930-671-24 Table 4-2.  DS/GS Troubleshooting  Procedures - CONT:. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION ENGINE (CONT.) 3. A LOSS OF POWER - CONT. Step 2. Check that fuel injection pump timing is properly set (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injection pump timing is not set properly, set timing (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injection pump timing is set properly, injection pump is faulty.  Replace injection pump (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). 4. OIL CONSUMPTION ABOVE NORMAL. Step 1. Check engine compression at each cylinder. If compression at any cylinder is below 325 psi (2241 kPa), or compression varies more than 40 psi (276 kPa) across all of the cylinders, go to step 2. If compression at all cylinders is at least 325 psi (2241 kPa), or compression does not vary more than 40 psi (276 kPa) across all of the cylinders, notify supervisor. Step 2. Remove fuel injector from cylinder with lowest compression rating, squirt oil into cylinder, install fuel injector, and then check compression at that cylinder (Appendix F, Engine Compression Pressure Test, Section 4.6). If compression reading rises for that cylinder, faulty compression rings are indicated.  Overhaul engine (Appendix F, Continentel Diesel Engine, Section 4.14, Section 8). If compression reading does not rise for that cylinder, sticking or burnt valve is indicated. Remove and repair cylinder head assembly (Appendix F, Continentel Diesel Engine, Section 4.14, Section 8). 5. BLACK EXHAUST SMOKE. Step 1. Check for faulty fuel injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is faulty, replace injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is OK, go to step 2. 4-3
