Brand new here, and found your site from a google search. I致e owned a L245DT tractor for about 7 years and its been a great and reliable tractor!
Recently, the tractors 3pt hitch stopped lifting, not even without an implement attached to it. It started by being intermittent sometimes it would work, sometimes not. Now it doesn稚 work at all.
The 3pt is driven by the hydro pump attached to the right side of the engine.(21hp diesel). The FEL is driven from a pump attached to the front of the crank. I realize the FEL needs pressures around 2500lbs... but not sure about pressure to the piston driving the 3pt.
I致e cleaned the filter screen, changed the Hydro/Trans oil. Checked the pressure relief valve in the pump attached to the rear of the trans and it seemed fine(no junk in it). I pulled the cover off the 3pt piston, and the cylinder/piston seems fine, I was able to pull it out and check/clean it. The O-ring on the piston seems fine as well.
I started the tractor and at idle no oil came out of the port that energizes the piston/3pt (lower right corner of the piston cover flange). When I ran the RPM up oil starts to flow out of the port.
I took a pressure reading right at the feed to drive the piston for the 3pt.(lower right side of the knob/cover over the 3pt piston) Im getting 30psi at full throttle. If idle, doesnt appear to be enough pressure to reg on the gauge. Also, when I had the plug out, there was no flow until near full throttle.
I took pressure readings at the port going into the side of the trans that I believe drives the 3pt. 90psi...
I suspect thats my problem...?
(not sure on the pressure required to drive the 3pt piston)
I suspect its my pump. If so, are they user rebuildable? If not, any idea what these things cost? It looks brand new compared to the tractor.
