Cool Websites

I found an interesting website that has some animations on different hydraulic components here:

The internal radial piston motor is exactly like the tracked loader motors, and the orbit motor is for wheeled loaders. Also the animation on the variable piston pump with moving swashplate is common, and this site has a film of it in action:

In case you were wondering....=)

Thats an excellent display of how a rotating group works. You can try to explain it for hours to someone that doesn't understand but thats so simple. From my limited experience with piston pumps, they are all essentially the same. There are minor differences between brands but the basics are all the same, rotating group that you adjust the amount the pistons can move with adjusting the angle of the yoke.
As for the gear pump, i originally thought the oil was pressurized through the middle, and not on the outside, this diagram clears that up too.
