Jason, I have all the parts you may need. E-mail me @ TE20ferguson at the domain AOL.com
That said there are a couple of other items to examine.
Where is the steady stream coming from... A crack in the lift cylinder or out the back edge. This may be hard to get the right angle on with out climbing under the trator with a turning PTO so put the cover on if you got one.
If a crack then replacing the cylinder is in order. If coming out the back edge then the piston rings may be gone.
To fix pull the lift cover:
1: disconnect the 3-point ( both link arms and the draft control spring at the rocker arm.
2: Remove the seat
3: gently pull the lift fork arms off the hydraulic pump"s control valve. (down in the oil) You may need to remove the control fork yoke if you have it (remove bolt from one side is fine)
4: remove bolts around the primiter of top cover note positions (there are 4 long, 3 medium and the rest short bolts I remember, may be a little different) The four bolts in the middle fwd of the seat hold the piston on. Do not remove these at this time.
5: Pull top cover up out of the diffy case be careful of the lift forks (help to have a friend, as it is heavy)
You can now trouble shoot and replace what is needed. The piston can be pulled and new rings replaced if that is needed. If you need a new piston, cylinder etc. then e-mail me and I can hook you up better than the $92.00 new cost.
E-mail me if you have questions or need further assistance.
