Ayup, sounds like the lift cylinder seal is shot. You mite be able to see it if you unscrew the hydraulic oil filler cap and look inside with a flashlite. Chances are you will see the oil spraying out of the cylinder bore when the tractor is running and 3 pt raised. Be cautious as the oil is under pressure.
You will have to pull the rockshaft housing under the seat to access the cylinder to install the repair kit. It wouldnt hurt to hone out the cylinder if it shows wear or is scored a bit. I rebuilt my 2440 cylinder a few years back and it was relatively easy. I dont think I had to dump my hyd oil to do the job. Warming up the new o-rings in hot hyd oil helped reassembly. Chances are the 3pt chatter/jerking will stop also. Thats usually cause by the oil spraying out of lift cylinder and accumulating tiny air bubbles that go thru the pump system. Another way for air to enter the system is if your pto brake is shot.
Anyone else want to add or correct something here?
