steering pump body modification
 

Hello, i'm Slah from Tunisia, and this is my first post.

i want to explore the hydraulic world so i'm manufacturing an excavator. I have some experience with electric RC trucks, excavators, planes and cars, and now i want to convert to hydraulic because it's amazing and more powerful.

The big problem is that we havn't a supplier for pumps and i havn't much money to buy from other countries and internet shops. so the idea is to modify a power steering pump from a car and use it in my first project.

i have found a pump like this one :

the main Body is big so i want to redezign a new body like a cylindre and the heart of the pump will fits in. the diameter of the heart is about 45mm, so i think the whole new pump will have 50mm.

have anyone of you know a good idea to build the new casing for the pump?

i have an idea and i'm drawing it with some softs and i will show you the design when its ready, but for now i want some comments from members here.

Thank you.
Slah

Any suggestion?

What is the pump from? I'm sure you could make it work but it will be overkill. You will need a lot of power to turn it but probably won't need to spin it very fast.

Good luck with it! I will be on the lookout for something similar the next time I'm at a junkyard.
