    Default 4030 John Deere oil leak

    I do not have a shop manual for this tractor. It has developed an oil leak on the base where the oil filter screws on. There are two metal oil lines about the size of a penny that run into the base of the oil filter housing. The lower line is leaking where it joins the base. Due these lines screw into the base or is there just some O rings where it slides in ? Any help appreciated.
    Thank you

    4030 John Deere oil leak-r22104_________un01jan94.gifThere are orings where lines slide in. I am assuming you have earlier style like diagram. Later style did not have oil lines, only coolant. Part number is T13119.

    Lubrication of tubes helps not to damage the o-rings.
