Introduction
For Specifications with illustrations, make reference to Specification For 3406C Generator Set Engines, RENR1292. If the Specifications in RENR1292 are not the same as the Systems Operation and the Testing & Adjusting, look at the printing date on the front cover of each book. Use the Specifications given in the book with the latest date.Troubleshooting
Troubleshooting can be difficult. The Troubleshooting Index gives a list of possible problems. To make a repair to a problem, make reference to the cause and correction on the pages that follow.This list of problems, causes, and corrections will only give an indication of where a possible problem can be, and what repairs are needed. Normally, more or other repair work is needed beyond the recommendations in the list.Remember that a problem is not normally caused only by one part, but by the relation of one part with other parts. This list is only a guide and cannot give all possible problems and corrections. The service personnel must find the problem and its source, then make the necessary repairs.1. Engine Crankshaft Will Not Turn When Start Switch Is On.2. Engine Will Not Start.3. Engine Misfires Or Rungs Rough.4. Stall At Low RPM.5. Sudden Changes in Engine RPM.6. Not Enough Power.7. Too Much Vibration.8. Loud Combustion Noise.9. Valve Train Noise (Clicking).10. Oil In Cooling System.11. Mechanical Noise (Knock) In Engine.12. Fuel Consumption Too High.13. Loud Valve Train Noise.14. Too Much Valve Lash.15. Valve Rotocoil Or Spring Lock Is Free.16. Oil At The Exhaust.17. Little Or No Valve Lash.18. Engine Has Early Wear.19. Coolant In Lubrication Oil.20. Too Much Black Or Gray Smoke.21. Too Much White Or Blue Smoke.22. Engine Has Low Oil Pressure.23. Engine Uses Too Much Lubrication Oil.24. Engine Coolant Is Too Hot.25. Exhaust Temperature Is Too High.26. Starting Motor Does Not Turn.27. Alternator Gives No Charge. Problem 1: Engine Crankshaft Will Not Turn When Start Switch Is On Probable Cause:1. Battery Has Low Output Make Reference to Problem 26.2. Wires or Switches Have Defect Make Reference to Problem 26.3. Starting Motor Solenoid Has A Defect Make Reference to Problem 26.4. Starting Motor Has a Defect Make Reference to Problem 26.5. Inside Problem Prevents Engine Crankshaft From Turning If the crankshaft can not be turned after the driven equipment is disconnected, remove the fuel injection nozzles and check for fluid in the cylinders when the crankshaft is turned. If fluid in the cylinders is not the problem, the engine must be disassembled to check for other inside problems. Some of these inside problems are bearing seizure, piston seizure, or wrong pistons installed in the engine. Problem 2: Engine Will Not Start Probable Cause:1. Starting Motor Turns Too Slow Make Reference to Problem 27.2. Dirty Fuel Filter Install new fuel filter.3. Dirty or Broken Fuel Lines Clean or install new fuel lines as necessary.4. Fuel Transfer Pump At starting rpm, the minimum fuel pressure for fuel transfer pump must be 20 kPa (3 psi). If fuel pressure is less than 20 kPa (3 psi), change
