I just purchased a Gehl 3000 1976-79 I believe. Got it cheap, it runs and operates. Every cylinder leaks to some degree. Anyway I'm changing all the fluids and I drained the Pump Drive that connects to the engine and the oil came out white milky. The fluid was low on the dipstick before I drained it. There are leaks everywhere but I'm not overly concerned since I will check fluids regularly and fix leaks as I can. But is this a huge red flag for my pump drive unit? The manual says to flush the pump for 10 minutes with #2 fuel oil and then drain and fill with #10 non detergent hydraulic oil. I'm going to try this and cross my fingers...
