Complete Fluid Change on Vintage Mini Excavator

The day has come and I'm finally digging into this new-to-me Takeuchi TB15 mini excavator. Whenever I buy a piece of older heavy equipment I always find something I didn't know before I bought it. Today is no exception as I dive deeper into the finer parts of the mini ex in search of all the good and hopefully very little of the bad. I'll do a complete once-over of all the fluids and change them where necessary. I'll tackle the engine oil/filter, hydraulic oil/filter, fuel filter, hydraulic pickup screen and water/fuel separator. When it's all said and done I"ll have a machine that I"m confident in that I hope I can put to work without any let downs. Here's to hoping anyways. With a variety of past owners of this machine, I'm surely to find some cobbled-together repairs and sketchy "improvements". Let's just hope those are few and far in-between. Here we go!
