    2630 with 145 loader problems

    The current loader boom moves very slow, the bucket works slow but has pressure.
    The boom will not lift the front of the tractor off the ground but the bucket will.
    The boom control lever makes a hissing noise when trying to lift the front wheels.

    Also, after working the tractor for 30 minutes the loader stops lifting and the engine starts to run warm.

    ANY OTHER SUGGESTIONS?

    This is the additional information you request to give me a quote for a new loader control valve.

    My tractor is a John Deere 2630.
    The loader model Number is 145.

    The Model number is 30512AA(R or J) cannot make out the last number.
    Other numbers on the control valve are:
    1B 13 TW
    C/N PAT 1959 USPAT 2676502 22675762

    2 Spool
    Closed System
    Dual Control
    Boom Float

    What is a replacement control valve for me.

    Welcome to GTT
    Many things can cause the closed center hyd system on tractors such as your 2630 to fail after operating for a few minutes. Any internal hyd leak can cause hyd oil to heat lowering oil viscosity & rob trans pump output to frt pump. A simple test to check FEL control valve is disconnect valve return hose from tractor them aim open hose in tractor hyd filler hole or 5 gallon bucket. With FEL valve control levers in neutral start engine & no oil should exit open return hose. If oil exits hose be sure if valve has a relief valve that it's **completely closed** because CC FEL valve doesn't have a need for a built in relief valve because hyd pressure is controlled by stroke control valve in frt hyd pump. Another cause for oil to exit open return hose during this test is blown inner seal on CC plug if applicable.

    Does your tractor have options of hyd ind pto &/or hyd reverser/hi-lo? With 3 pt raised/engine running look in hyd filler hole behind seat for moving oil which indicates leaking 3 pt control valve seals.

    fel test 2630

    I will try testing FEL today. Thank you.
    Now is the FEL the quick connect line from the Control Valve to the tractor?

    Tractor does not have reverser. or mid PTO.

    Second question in your post does not make sense to me

    How long have you had the tractor/loader? Did it operate correctly and now has a problem, or has it been this way since you got it?


    Have you:

    Checked hydraulic oil level?
    Changed trans filter?
    Cleaned sump screen?
    Checked system pressure?

    When you say engine gets warm after 30 minutes, how warm? What does temp gauge show? On my 2030 it runs (temp gauge) needle straight up at operating temp.

    When I look in the filler oil I do not see any oil.

    Both of my hoses have quick connects. should I take off the disconnect coupling?

    Yes to all your questions plus changed oil. I just purchased this 2630.... When I changed the oil it had 20 gals of oil in the trans. not 10 as the book says...

    The temp creeps up into the red and keeps going.....
