hehe Posted November 23, 2015 Share Posted November 23, 2015 What model? Sounds like you are having multiple engine generators failing? In flight, on ground, same engine? Give some details please. Just want to clarify your issue before I throw out ideas Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted November 23, 2015 Share Posted November 23, 2015 Check and make sure the Voltage Reg manufacture is the same as the Generator; there are two different types with different operating voltages. The newer system can tell what GEN/VR is installed the older cannot and may cause failure. You may have a "Bus" failure if it is the same Gen each time. A second Gen failure on the same wing when the load is switched would be a good indication of a Bus failure . Quote Link to comment Share on other sites More sharing options...

Bogi252 Posted November 24, 2015 Share Posted November 24, 2015 Dear Mr. Munir, First concern is oil splashing on the generator! from what source? This is not normal and must be fixed before running engine or installing replacement generator. Potential fire hazzard. We represent the manufacturer of the generator you mention. We can perform a teardown and report exact cause of failures. Also we can offer alternative gen in NEW condition with 3 yr warranty, as a more readily available modernization. Lastly, we have RRC with PAF. Regards. Quote Link to comment Share on other sites More sharing options...
munirabbasi Posted November 25, 2015 Author Share Posted November 25, 2015 Thanks Mr Bogi252 Oil source is engine RGB generator spline. regarding generator offering, q? free of cast for marketing. lockheed marten only recommend bendex or leyland specification. i need reason for generator burning munir abbasi Quote Link to comment Share on other sites More sharing options...
Bogi252 Posted November 25, 2015 Share Posted November 25, 2015 Munir, the Bendix are now Honeywell PN 28B58-9B. Reason for failure (burning) can only be determined after a shop teardown, but if oil splashing was abundant enough, probably shorted components internally. Im available at [email protected].
