I have a j.d. 2010 , early 1962.The hyd. pump growls all of the time ,colder weather makes it worse. I am guessing it may be sucking air some where. Does anyone know where I could find replacement bushings for the pump? I can not find any for the 10 series tractors, they are listed as NLA. they are a split bushing with metal on the outside and bronze on the inside. 1 1/4 I.D. X 1 3/8 O.D. X 1' long. J D# T 13780. Any help will be greatly appreciated. Thanks, Don
