massey ferguson 35 hydraulics

I bought a Ferguson 40 and it would go all the way up and then I
noticed the stop was in place. 1/4" bolt wouldn't let the lever
go all the way up.
 
If the draft control lever is all the way up, and the position control lever is all the way up and it only raises half way up something in the internal linkage is broke, or its out of adjustment.

Where can I find a detailed picture of the hydraulic system? I have a manual but the pictures are terrible.
 
Most of the MF manuals don't have the greatest pictures, is it a copy of, or is it a real MF manual (there are some real bad reproduction manuals being sold). There are some DVD's out there showing how the hydraulics work, how to rebuild, and how to adjust them also.

(quoted from post at 08:19:49 10/31/16) Do you have the draft control lever all the way up?

How's the condition of the hydraulic oil? Good and clean? If so, it could just be the control valve lever nut that's backed off too far. It's a nylock nut, and often the nylon is worn off the end so it backs off with vibration. (speaking from experience)

Try pulling the dipstick plate off the right side, tractor off, wheels blocked. The nut should be 7/16" if I remember correctly, threaded onto the end of the metal rod on which the control valve lever pivots. Tighten it up just a bit, if you go too much it'll constantly pump which is obviously no good.
 
Sorry for the doublepost, the forum won't let me edit my previous one.

I got the hydraulic system rebuild DVD from http://vintagetractorengineer.com/maintenance-dvds/

It's fantastic and breaks everything down quite easily. Just make sure you pay very careful attention.

Thank you for the link. As I understand it, the MF202 workbull is the industrial version of the MF35. So, I'm guessing the hydraulics would be the same in both machines?

You're welcome!

They're pretty much an identical machine except for the bodywork and a heavy duty front axle. My cousin's 202 is functionally identical to my 35 Utility (also an industrial variant) in every way except for the tinwork.

The rear hydraulics are identical to the MF35, just be aware that depending on the year of your machine there are two different hydraulic pumps (one with a filter screen, one without on the older units), and two different pressure relief valves. You need to match the pressure relief valve to the pump, and make sure it's a factory MASSEY FERGUSON part, not cheap ebay junk. If it doesn't function properly it could quite easily ruin your pump.

Also forgot that with the heavy duty front axle, the industrial versions were available with a manual shuttle shift and REAL power steering with rams that actually turn the wheels, rather than hydraulic assist)

Yeah, the steering on mine has a cylinder on each front wheel. It will steer with one finger. I also love the foot throttle. :D The Hi / Lo transmission ain't bad either.

The 202 is just a heavy duty 35, the 3 point hydraulics are the same.

It's also got the heavy duty straight front axle. Made for handling a FEL.

Anyway, I ordered the DVD so I'll wait until I get it before doing anything with the 3 point lift.
