A reader suggested that I should write about more complicated repairs. He wants to learn how to rebuild engines and work on transmissions. Beyond the challenge of explaining such complex repairs in a 250-word blog or 600 word magazine column, I'm not sure what to write about. Because at their core, complex repairs are just simple repairs done in the right sequence.
Replacing a bearing in a transmission is as simple as removing the old bearing and installing a new bearing. But GETTING to the bearing is the challenge. Having the right jacks and supports and tools to remove a cab, knowing how to split the tractor, knowing the tricks to dealing with hydraulic lines and electrical wiring harnesses---there's nothing super-complicated about any of the steps. It's just getting them all done in the correct sequence with a minimum of fuss.
Sure, there are complicated aspects to major repairs--preloading bearings, setting backlash on gears--but most professional mechanics rely on tech books to walk them through the complicated stuff. A few veterans who specialize may have the intricate procedures memorized, but those guys are magicians who don't live in my world.
In my world, I trudge through repairs relying on tech books and hard-learned experience. I view every repair, no matter how complicated, as a series of simple steps that I just have to do in sequence, correctly. Most of the time, it works out okay.
