MB 18N genset was a diesel powered generator in the 60/50 cycle 1800/1500 rpm 110, /190, 220/380. 340/ 416 range 38 (60 kva )/28 (50kva) KVA depending on the wired output. Most had a straight six White engine, rad fluid preheater by south wind and were primarily an Air Force Asset used to power hardened facilities that had mission essiential functions , command posts , hospitals, Nuclear Missile top shacks ect. They were usually set on concrete pads or in sheds and maintained by Prime Power in CE. primary T.O. / Technical Order. not T.M. was 35C2-3-342-1-3-4 Hours were usually very low and they were routinely overhauled at the Air Force Depot. Our Command Post started them once a month and ran them half an hour to an hour, Biggest problem with them was LACK of use . I picked one up from Loring AFB closure a while ago. Set up and operation is more complex than a MEP , BE VERY CAREFUL STARTING AND OPERATING UNTIL YOU ARE FAMILIAR WITH THE OPERATIONs MANUAL . I have a copy of the T.O. some where, been looking for it since a fellow member requested it. Air force manuals were called Technical Orders because their step by step use was required by Regulation on every task, The ENTIRE MANUAL WAS CONSIDERED A LEGAL ORDER UNDER THE JUSIDICTION OF THE SECRETARY OF THE AIR FORCE. More than one Airmen was given Article Fifteens or Court Marshalled based on Technical Order violations or not using one. ALL Air force Maintainence was covered by Technical Orders. If you were working a jet you better have your T.O. or ten, You had to have the instructions for any thing you may have worked on , Normally carried at least three full T.O.s , A lauch truck for Propulsion had an entire rack of the entire jet engine series on it in numerous sets to use on the flightline by any number of mechs. The only other option was a J.G. (Job Guide) an abbreviated T.O. that was used sometimes. Not having the correct Manual got your Flight Chief chewed and your butt chewed by the Col. then the DCM , Deputy Commander for Maintenance , not a good day . They were reliable and very well made, Albeit complex on the electrical side, Parts , relays, voltage regulators ect are hard to come by and very unit specific. Most went to the bone yard
