How do I get the drawing of a hydraulic motor?

Hi 550166681,

Drawings of a real scale motor/reducer are easy to find on the net, search for excavator hydraulic final drive, excavator wheel drive, excavator wheel reducer, or something alike.

But in the case of a reproduction in 1/14,5 or even in 1/12 the drawings you can find are quite worthless. You can't downscale and replicate the complex design of a real motoreducer in a model. You have to make your own project symplifing a lot, reducing the number of components in the assembly and fixing your attention on efficiency.
And it's very hard, both the design and the build.
