Does the pump struggle or give no pressure? You might need to reset the control linkage, but if you turn the pump by hand blocking the feed pipe you'll either find the pump becomes very difficult to turn or that it just keeps going, in which case you'll need to replace the drive gear key. Try doing a pressure test too, to see if the relief valve is ok. Some pics of what's happening would be helpful too.

Re: Fordson Selene
could the unload valve be stuck ,
Re: Fordson Selene
Very good point, one that I mentioned in other posts and strangely it never crossed my mind this time! The unloading valve controlls lifting, it often sticks preventing the hydraulics from working. Well worth looking at.

Gentlemen
Progress………
I changed the the Hydraulic ram cylinder as per fig 30 in the parts manual on page 74 from the donor tractor. This got the hydraulic system going. We are very happy with the results.
Arms in place
Roll bar in place
Wings mounted
Next tasks
Give the back wheels a brush down with the wire brush on the grinder
Install seat.
Prepare to split tractor to replace hand brake disc’s
Get steering box from donor tractor an install on Selene
Check what type of raised pto I have and see if it will fit.
This leads me to my next query
How do you tell the difference when it comes to Raised pros for super major v np super major. I know there is a difference but not what it is.
Any help would be appreciated

Additional query
Is there official guidance on tyre size for fordson major tractor with Selene axle?
I would like to place as big as possible tyres on the back and what ever is appropriate for the front

Re: Fordson Selene
Hi,
The old style raised pto has a gear ratio to make the pto slower and have 540 at higher engine rpm. The newer style has a 1:1 gear ratio.
Just check whether in and out have the same number of revs when turning by hand and counting. Or count the number of teeth on the gears.

Re: Fordson Selene
The NP raised PTO has a cover with four holes only and it's not round, this one is 1:1. The earlier raised PTO has a round cover with 8 holes (only 4 bolts) and it's round, this one is 1.33:1. I don't know which one you need, but you can tell from the PTO casting under the gearbox, if it's very big next to your Diesel Major it's the NP one, if it's the same as the Diesel Major it's the earlier one.
