Phan 14 #1 Posted September 3 Dear All, Could anyone advise me? Please see the clip and photo. The leaking oil is from the cup and the first inner hose. I cleaned the cup and there is no shim? I have not removed the hose yet. IMG_4890_Dripping_oil_-_Edit.mp4 Share this post Link to post Share on other sites
daveoman1966 3,752 #2 Posted September 3 (edited) There are O-rings in the 'cup'--- item #22 in this schematic, although a part # for item #22 is not given. These O-rings are on the shaft in the body of the hyd valve. Edited September 3 by daveoman1966 Share this post Link to post Share on other sites

oliver2-44 9,787 #4 Posted September 3 The component your videoing is you hydraulic lift valve, not your pump. I like to clean the outside of everything in the area ready dry and clean. Then start the tractor to try and pinpoint where the leak is actually coming from. It might just be an O-ring on the hose fitting, or it might be the fitting itself. The cup is your pressure relieve, don't turn the components in or out as that would change the setting. Share this post Link to post Share on other sites
