It's not difficult. But you need to have (of course) all the oil and filters required prior to starting. I purchased all of mine at "filterbarn.com". And a container than can handle 19 quarts of used oil. You may want to think about getting a Fumoto valve to replace the drain plug....with it, draining the oil is much easier and less messy.
Some diesels (my Safari did) have a protective cage under the engine that has to be removed first (four bolts). Then you will find the oil filter on the driver's side of the engine and usually is on really tight. My CAT had two fuel filters, one with an fuel/water separator and another without. Both of my fuel filters were accessible through the compartment door that houses the AC radiator (it pivots out of the way).
When installing the oil filter, I filled the new filter with fresh oil and put a light coating on the oil filter gasket. Make sure the mating surface is free of dirt and old gasket. Did the same with both fuel filters only use fresh diesel fuel to fill and light coating of fresh oil on the gasket. I then would only tighten each filter as tight as I could using only my hands.
You should also have a hydraulic filter that needs to be changed, large air filter, and possibly the dryer filter.
Then every three or four years you need to change out the trans filters (2) and install new Transynd fluid.
Don't forget that the generator also needs oil/filter maintenance too!
Hope this helps
