Some other interesting facts, The engine oil tank was gold plated and the oil was XD2 (Had to be accounted for, rather than just disposed of ) when I worked them At Mildenhall , we did iso insps and minor mait, engine changes line work ect DET 4 . I was the project manager for the construction of the first flow thru "full AB run certified hangar at MHZ" (hush house)before I left Major maintainence was done at the primary DET , THe turbine shaft would be so "STUCK" when you wanted to pull it they actually had a special tool consisting of a torch on a shaft to run down the shaft and cut it off to get it off. The engines were kept on the spare line BAGGED right NEXT TO C- 130E ,T 56-7A TURBOJET ENGINE SPARES. when GUYS USED TO COME IN LOOKING FOR THE SUPER SECRET ENGINES WE USED TO POINT TO THE Tt 56 SPARELINE AND SANDWICHED BETWEEN THEM AND SOME j 57 59 w AND tF -33 SPARES THEY SAT, no one ever looked at them LOL, THe only person you didn't want to be was the TEF or TEP man , (chemical oxidizer used to propagate fuel lite off, combusted on exposure to air) look it up you will get a chuckle. Good jet , AF was sad to see them go, it was the beginning of the end, They did return to flight briefly after the gulf war, some stood up for duty and were never given a single noteworthy tasking, POLITICS, then they were slowly bled to death and sent packing again, Best part working them was NEVER having to get funding approval for parts ! I saw my first one in 1976 and last worked one in 1986, Was an easy way to get back overseas with that SEI (special Equipment /Engine Identifier) Guys would say, "NO way your getting an assignment, I would go to assignments and be back in a few hours with soft orders back to Mildenhall . LMAO all the way .
