I have a 574 with similar issues to what many have posted on here. No hydraulics. I purchased the tractor over the summer and have been working on it since then. The MCV has had all the o-rings replaced since I purchased it, good flow coming from the hydraulic pump, but the previous owners appear to have put an incorrect flow divider and spring in the MCV. To even thread the plug into the MCV the spring has to be compressed. Purchased a new flow divider that is supposedly for the 574. The spring and FD definitely looked different and the spring didn't need to be compressed to install the parts. Problem is, with the new parts the hydraulics still don't work. Symptom is no hydraulics to the loader, 3pt, etc. with the flow divider installed, but the power steering works fine. Remove the flow divider and the power steering doesn"t function, but the loader, etc. works as expected. Can block flow from the loader controls and I have PS. So, I am confident everything past the MCV is functioning as expected. Am completely at a loss what"s happening...

I really appreciate any help or suggestions people have...

Fortunately when you step into your shop and make that jump 50 years back in time to work with your old tractor, this concept goes out the window. Even so, when it comes to the charging system, people quickly revert to this idea and start replacing the major components one at a time until it works. The reason you don't find any decals in your replacement set wit
