I like your pump. How did you do it?

[RCP57]

I didn't make the pump itself. My father in-law machined the inner case on a cnc mill to fit some internal gears that I had and then I machined the outside down as much as I could to decrease the size. The gears are from a motorcycle oil pump and are more designed for volume than pressure but it still pumps 25bar with ease. I'm not sure how long the aluminum case will last. It was our intention to try this pump and if it worked, make the cases from brass or steel. I have another case just like this one and a few sets of gears so I can make one more if this one wears quickly. My current drive setup is the original from my excavator and spins the pump way too fast for this machine. Pump speed is close to 6000rpm if I don't dial it back and the pump makes a lot of volume. I need to get a lower KV motor because the speed control gets hot running at a reduced speed all the time. Either that or get a smaller pump, hence my question about the RC4WD pump and motor.
