3-Point Hitch Massey 150 strange hydraulic issues

[SIMassey]

Also if I do add the two spool valve running off of the right stick, what do I do with the left stick? Do I plug the outputs that are currently plumbed to the bucket curl?

Yes, plug the ports on the left hand valve after disconnecting the bucket hoses. You should be able to get plugs with o-ring seals. I think the thread and pitch is a 3/4 -16.



After the hoses are removed and ports plugged, you should be able to run both the position lever and draft lever in transport position and raise and lower the three point with the left hand lever. If you are needing precise height control on the three point, lock the left hand lever back toward the seat and use the position lever to raise and lower the three point to the height desired. If it doesn't work, post back and I will explain the final needed adjustments to the valve. When ordering a new two spool valve, consider a joy stick, it will be even more convenient than an old style two spool valve. I don't think the price is much different. J. J. on the hydraulics forum usually suggests a brand hydraulics joystick. Its rated for a maximum of 10 gallons per minute. The Massey pump only puts out about 4.5 gallons per minute. This valve is avalible from surplus supply. Check out the hydraulics forum with a search and you should get lots of threads.

Yes I like the idea of joystick control. I just found one on sale at a local store and am hopefully picking it up today. So, I will have to feed this joystick from the right stick. Does this mean I will always have to have that stick pulled back? Or is there a way to disable the valve portion and have it constantly feeding hydraulic fluid?

If you keep the Massey valve, to use the loader, you will need to center the left valve, and pull and hold the right hand lever to supply a constant flow of oil to the new valve. To use the three point you will need to pull and hold the left hand valve and center the right hand valve.

You could replace the two spool massey valve with a divirter valve. This may be a bit more simple than using the Massey valve. The divirter valve will need to be shifted to run either the three point or the loader. You can google "massey ferguson 150 hydraulic valve" and you should get several sites.

When removing the Massey Valve, lower the three point arms completely when removing the Massey valve to relieve stored fluid in the lift cylinder in the three point. Carefully remove the the valve. There are o-rings and teflon seal rings that retain the standpipe that goes down into the main pump. If the standpipe pulls out you must drain off a couple gallons of fluid and remove the draft speed cover on the right hand side of the differential housing (the one with the dipstick) and replace the orings on the standpipe and guide the standpipe correctly into the hydraulic pump.

I think someone posted an entire thread detailing this procedure.

Switching to a divirter valve will of course add additional cost but may offer a cleaner and smaller hookup elliminating the large valve on top the transmission. You could then sell the Massey valve on e-bay to offset the cost of the joystick and additional hoses and fittings. The new valve should have power beyond which will allow you to add another valve downstream should you ever decide you need rear remotes.

Be advised, a couple of years ago, someone was trying to remove his Massey valve and had a very difficult time. It is held down with two socket head cap screw, the kind with the internal hex for use with an allen wrench. Well, the tractor sat out sometime in its life and got water in the counterbore where the head of the bolt is and rusted so bad he had to drill the head off to remove it. Just a word of warning. Socket head cap screws are generally a grade 8 and tough as nails to drill. If you are on a tight schedule, you may need to allow more time for problems such as the bolts and standpipe.
