I did a stint of instruction in the Army. I taught the operation and theory of the Combat Engineer Tractor, and how to maintain it in barracks and in the field. I have changed over 6 engines, these are big C6TFR Rolls Royce diesel engines that require a big crane and a lot of nerve to remove, as they have less then an inch of clearance on the way out! I have also removed the gearbox, a nightmare job but I have done three or four! I've changed Fuel Injection Pumps, injectors, fixed BCF fire extinguishers, the odd bulb or two! I've done all sorts on them, and though many CET Operators hated them with a passion, I loved the challenge of working on them. I also loved to teach other people, whether they wanted to learn or not, about the finer details in how they tick. I diagnosed hydraulic faults in the gearboxes that nobody knew about and a vehicle that had been off the road for months was working in ten minutes! Others learnt from my experience.
When it came to the actual course though, I hated instructing parts of the course. Some of it was so boring, not required, out of date or whatever, but the syllabus had to be adhered to. There were better ways of doing things, but the syllabus ruled. I could have sat in the guts of that vehicle everyday, if people had left me be and taught people how to really operate it, but that was not to be.
After four weeks of instructing, I was glad to finish the course off, the first week and a bit was all classroom and very tedious, but the driving instruction and digging operations were great fun, if not sometimes a little scary!
