    1972 2030 Which Hydraulic Pump?

    I have a 1972 John Deer 2030:
    Type - T5R3C
    Serial# - 141343T
    w/John Deere Model 46 Loader

    I'm want to add some loader attached implements other than the bucket. Looking at implements, the hydraulic system gpm rate comes into play. I have a copy of the service manual and it states the tractor could have one of two main hydraulic pumps. Option 1 is a 1.38 cu. in. that has a flow rate of 9.5 gpm and option 2 is a 2.40 cu. in. that has a flow rate of 18.5 gpm.

    Can anyone tell me how to identify which pump my tractor has?

    1.38 ci pump

    The cover on the front of the pump(retained by 8 hex bolts) will have an "Indention" in the center.

    -----------------------------------------------------------------
    2.4 ci pump




    The 2.4 ci pump has 4 hex bolt retaining the cover. The cover is flat.

    Perfect Michael. Thank you very very much.....

    I'm hoping it has the 2.4 allowing more implement options. If it has the 1.83, do you know if they are interchangeable so I could buy a 2.4 and replace the original?

    They are interchangable. The pump drive will need to be replaced also.

    What type of attachment are you adding? Do you need more displacement?

    Brush grapple and a tree shear.
    For the tree shear:
    hHydraulic flow requirement 10 gpm* (minimum)
    Hydraulic pressure requirement 1,700 psi* (minimum)

    There will also be hydraulic line changes.

    Also the PCV (Pressure Control Valve) uses a different internal valve (key 17), a sleeve (also called a stop) key 18, which is NOT present with the 1.38cu pump. See attached parts drawing. Fitting key 20 is different too.

    It might be easier/cheaper to use a PTO driven pump for the flow hungry attachments
