Massey 50ex

[Cms]

Hi all.
I've changed the back end oil and put in a new filter(genuine) after the hydraulics became very slow and the steering non existant. However this has not improved the situation. The lift arms won't go down ,no matter where the quadrant levers are set at. The loader barely lifts or tilts and the steering is jammed solid. Amy advice would be greatly appreciated. Tia.

The loader and internal hydraulics are totally seperate on this machine

It's not a torque converter if that makes any difference.

The loader has its own pump, reservoir and filter . The steering does from memory use the gearbox oil. Try doing a few lock to lock turns of the steering, lift the front axle off the ground first, this should bleed any air that got in the system when you changed the oil.
your lift arms may not drop due to lack of use and no weight on them. Try pushing them down by some means

Unfortunately the steering won't move and the loader hasn't enough power to lift the tractor off the ground.

Your steering issue sounds like it is the valve located in front of the radiator on top of the steering ram. However it would certainly be worth checking the pressure in the system, there must be a plug somewhere for the purpose. Afraid it is 40 years since I worked on MF machines.
the main loader hydraulics are very simple in comparison Have you checked the oil level by the drivers door on the frame? Not sure where the filter is on that model but will certainly need changing and quite likely the oil is milky and needs a total change. The oil is Hydraulic 32 , it could be someone has put other oil in here which is the issue.
you said you changed the oil, which oil did you change? I was assuming Gear box oil, did you use the correct oil in there? Is the level up to the mark?

There isn't a steering ram in front of the radiator, there's 1 on each side onto the axle. There isn't a dipstick or oil level gauge atvthr door frame. It's an 8x2 transmission. It looks more in common with a 290 . I get a few photos later.

You sure it is a 50EX?
is it possibly a bitsa?

You could be right, I'm only going by what it says on the bonnet

Are you sure it is not a 30 E industrial? Not sure the workings of those

don't think its a 50EX, my 50E had one steering ram on the offside just the same as the 50HX I have now

Found the problem. There's a filter in a housing and its blocked solid. Many thanks to all who gave advice, its greatly appreciated.

That looks like the MF 300 series set up.

The replacement filter is for a 300 series

Just seen the OP's pictures on another place... It's a MF 50 Highway tractor with a non MF loader added on,although it does also seem to say 50EX on the bonnet.It's not the 50EX model that the rest of us have been thinking off.

It's does say highway alright, what were the highway models about?

Most highway tractors were sold to say local councils for use in parks and gardens, or on road works, in the days before the grab wagons you see now, there could be tractors with loaders taking the spoil and tipping it into wagons, I can only go on David Brown models, they had 4 wheel braking wide fenders on the back wheels and fenders on the front wheels as well, brake lights and indicators, power steering, long before seeing them on Agricultural models, and the brakes would be a single pedal.
