Default Re: Hydraulic build for John Deer 850J dozer

I spent a bit more time on the build today. Resigned myself to the fact that this is going to take some time! A little more than I thought before I started. I'm going to blank the second function off and carry out some testing with the valve that is almost completed. Have to wait for some hose and a tap to arrive in the post.
Next on the list is a pump. Can anyone help me with the gear sizes of the smaller end pumps? OD and H. What RPM are the gear pumps run at?
