Massey Ferguson Workbull 202

Greetings! My first post here because I'm new to the tractor world. I just bought this ~1958 Massey Ferguson Work Bull tractor, with a MF102 loader and I believe a 220 (davis) backhoe. I got a good deal on it but the hydraulics need some TLC. Would appreciate some advice to get this tractor working properly. A few questions:

1) The loader valve is leaking badly from the seals, like a jugular vein. I'm going to take it off and bring it to a hydraulic guy but he's not confident he can fix. I think a good backup plan would be to get a modern valve, maybe with a float function, to operate the bucket / curl. What GPM do you think could replace this valve? I have the backhoe manual that references 18gpm, but the loader manual doesn't have specs.

2) A few of the pistons are leaking and I think need new seals --- one for the loader, and one for the return of the stabilizer. My dumb assumption is that pistons are pistons and that even if I can't get these resealed, I could plug and play new pistons with the same stroke / diameter and be on my way. But maybe they won't bolt up the same way, etc. What do you think?

Any other advice / comments / concerns / insults while I'm here? I bought this machine to clear some land at my house, remove some stumps, maybe dig a trench or two. It's hard to come by machines like this in the NY suburbs, so there aren't a lot of tractor mechanics I can consult with. I'm working with a hydraulic guy that fixes bobcats and forklifts to help with any of the hydraulic stuff that's beyond me. Thanks!

I also have a 1958 MF 202 with a backhoe and loader. The seal for your control valve is a Massey 1752350M1. I have a spare that I ordered from a dealer years ago that is marked C/R 7432. I think both parts are obsolete. I did find a cross reference for a SKF 7443 which should fit. If you send me an email, I can forward some info to you.

Hey! This is awesome thank you so much. It says I can't email you for some reason but if you want to give me yours or you can try to send me one, [email protected]. I will take whatever info I can get. I would love to rebuild
that valve rather than buy a new one, I will try and buy that seal.

I sent you a few files that should help.

If you didn't just happen to have the breather off the elbow, for this picture, you need to get and keep a breather installed to keep water and other crud out of the loader hydraulic reservoir.

It looks like that seal blew out on the spool. It's more to keep stuff out than in. I would say the spool is toast. Look at surplus center for the spool valve. Prince 25 GPM.

How does the chrome look on the cylinders that are leaking? If it's pitted, they need a re- chrome. New seals wont help. A good hydraulic shop should be able to advise. A re chrome ran me about $1000, it was cheaper than replacing both cylinders.

Appreciate all the advice and help so far. Getting there. Changed engine & coolant, cleaned the air filter. Going to pick up one loader cylinder that's been successfully rebuilt. Still working on some other stuff like the valve and the stabilizer cylinder, that I couldn't remove without buying a 1" crows foot wrench to remove the hydraulic fittings. I bought a breather as well.

For those of you with this tractor; I'm guessing this isn't how your accessories are plumbed. Maybe this tractor had the loader originally, and the back was retrofitted? I'm guessing this isn't a factory install. The fitting someone told me to get a breather for.... goes nowhere. I think if you just have the loader, the reservoir is this cavity, but my hydraulic reservoir is behind the PTO.
