Hydraulics on my new major
Hello,
Sins my fertilizer is mounted in my 3p hitch the lift arm drops rapidly. When I started to use the lift it went down in a night. That’s normal, I think. Now it lowers about an inch at a quarter of an hour. To much I think. I thought the piston ring was worn due to a bit of pit rust in the cylinder, so I have remove the hydraulic unit to check the cylinder. The piston ring looks all right and the pit rust is at a place were the piston ring will not come.
Next thought is that the problem is at a valve or something. Because I know nothing about hydraulics I don’t know were to begin or look for.
All help is welcome.

Hello,
Today I have removed the Unloading valve, Check valve and Piston valve from the valve body. All the seats looks all right to me. No wear.
When I overhauled the lift cover, I put a new piston seal on the ram cylinder piston. It looks more as a oil seal than a piston seal to me. It has a small chamfer at the front and it’s a bit stiff plastic.
Would anyone know how the original seal looks like and is it still available?

Hello Henk,
Did you install this part?
http://www.histoparts.com/oscommerce/ca ... ts_id=1475
You might have fitted it backwards, which will cause problems.
Can't help you with what the old seal looks like. When I read your desciption, it might be that one of the valves is not free moving in the system. Could you take them out easily or not?
Best regards
Emiel

Henk,
Is this any use? Its the new seal I had made and it works a treat. The PR Valve has been known to leak a bit depending on whether it is the needle version or the ball end version.
Yes we will all be in the gardens on the weekend after Easter. Are you and Janeke going this year? If so we would adjust our dates to fit in with you.

Hello,
Received a new piston seal yesterday, looks like the right shape to me, but it was to big. Outside it's 3,5 inch. The cylinder is 3 inch.
Could it be that the Super Major needs a bigger seal?
Also I ordered a new front crankshaft seal. This has a inner diameter from about66 mm, more than 2,5 inch. Looks to large to me. Anyone knows the right diameter?

Hi Henk,
I got myself a new crankseal too. It has about the same inner diameter. The outside diameter is about 90 mm.
I haven't tried it on the crankshaft yet.
If I remember well, the old crankshaftseal could move pretty easy on the crankshaft too.
I am curious what the correct width should be.

Fordson's don't leak oil, they are just marking their territory.

Thanks
I saw this post but I was under the impression the problem was inside, under the seat top plate. I'm not the mechanic, .

Not on a Major! Everything other than the pump, comes out the front without having to take the lift off. Very easy to fit a new piston seal.
Henk,
Just a thought, Have you got the pipe to the gearbox as a permanent fixture? If the tap was leaking slightly it would give your problem.

Ok
When I mowed with the pull mower it had a one way remote cylinder. Once I raised the arms up the diverted fluid raised the remote of course. The thing is the arms would drop right down but the remote stayed up with no problem until I moved the control down again as though I was lowering the arms. I enjoyed mowing with it.
A rare old International 7 foot haybine with crimp rollers but before the front reel was added.
Maybe I am mistaken about it riding in the up position, it has been a few years. I guess id did leak down as well.
Have to correct myself there. I just always managed to run it like that.

Hello,
This is my solution for dropping the lift arms. Not my idea, it's common use by stabilising a sprayer. Works perfect. The fertilise spreader is steady as a rock and it won't lower. Of course you can’t use it when you have to raze and lower an implement for the job.
