Troubleshooting
1Symptoms & remedies
| Symptom | Cause | Remedy |
|---|---|---|
| Heavier than normal lubricating oil consumption, and oil leaks from the air and exhaust manifolds | Turbocharger oil seals are not fully effective on light load which results in oil being delivered together with the air into the engine air manifolds. The cylinder temperatures are too low to ensure complete burning of all the fuel delivered. | Running on light load should be avoided or reduced to the minimum period. If weekly exercising on no load is carried out, the running period should be kept down to say, 10 minutes, or until the battery charging rate returns to normal. Periodically site load should be applied (min 25%) through the year. Every year the engine or generator set should be run for four hours, to burn off accumulations of carbon in the engine and exhaust system. This will require the use of a 'dummy load', which should be built up gradually from zero to the maximum over a four hour run. On standby sets, air cleaner elements should be changed annually. Lubricating oil and fuel filter elements should be changed every six months. The fuel pump injectors should be checked every 2 years. |
