8n hydraulics

I just bough a ford 8n.. the hydraulics pick up good and strong.. but when you depress clutch they drop pretty fast . is this normal? any suggestions.. Thanks in advance Shane
 
It usually mean the piston is leaking fluid past it, but if it doing what you want it to do, why worry. If you want bragging rights about how long it will stay up, then fix it.
 
Is it normal well yes on an old tractor that needs some TLC. Is it correct no and as others have said good chance it has a leaking cylinder rings. Pull the inspection cover off the right side start it up and watch for oil dripping. You may find you need to rebuild the lift cylinder and if you do it is best to replace with the new improved NAA type piston and rings
 
" what are the part numbers i will need"

That would depend on what's causing the problem.

You must have missed this part of tip # 16:

You probably have a worn lift cylinder or piston (or both), a blown top cover gasket or a leaky pressure relief valve.

Of course, if you just want to replace everything w/o diagnosing the problem, then you will need a relief valve, piston, cylinder & gaskets.

And while you're in there, you might just as well adjust the internal linkage.

You'll need a jig for that.

Trouble shoot first then worry about parts. This site sells them but I do not know the numbers off the top of my head
 
Also might be leaking pressure safety relief
valve..Had one that dropped so fast, the implement
would be on the ground before you could clutch it
and shift gears.--it was bad PSRV--look for
turbulence down low in the oil once you have
checked up above around the hyd. cylinder and other
places above oil level..
 
still havnt had chance to look at.. it was low on fluid... i see no leaks on ground... where on tractor its self( not inside)
should i look for leaks..
 
where on tractor its self (not inside) should i look for leaks..

JMOR drew this most excellent diagram to show the nine potential leak points - Check with side cover removed; lift loaded and elevated, and engine off. As others have indicated, eight is the most common leak point.
