I have a Deutz Allis 5215. Had a problem with the 3 point hitch not raising. I changed the fluid and filter and it worked fine for a few days then it stopped raising at all. The old filter was an Agco. I took that part number to NAPA and they crossed it to a Wix 333390. The Wix filter said fuel filter on it. I questioned the parts person about that and and he double checked the part number and said that was right. I disconnected the high pressure line under the pump placed a bucket under it and started the tractor. Fluid was barely coming out. I'm thinking this is the wrong filter and the SAE 80 gear oil will not flow thru the Wix filter. I have since ordered a Fram P7572 hydraulic filter and am waiting on delivery. Anyone have any thoughts on this? Thanks
