I am servicing the hydraulic filter on my IH 2505B with hydrostatic drive and a Neuss D239 engine. I am unsure if there is an additional suction screen other than the one in the filter housing. A friend suggested there may be one located on the transfer pump. Also, I am having difficulty locating the correct service manual. This tractor seems to be an industrial version of an IH 574. Your help will be greatly appreciated.
Try some searches over at redpower. This site is real low on International equipment knowledge.
Thanks Delmer, I will try redpower. Meanwhile, captin_wingnut posted an operators manual on Tractor Forum that addresses the hydraulic system maintenance, including the hydrostat filters. Thanks again.
