Hey guys, I just got a 59 fordson power major diesel and was wondering about changing fluids. It has the loader on the front, 3pt, live hydraulics and pto of course. It says sae 90 for trans and differential on a tag on the firewall but I can't find that anywhere. The engine also says straight 30w I believe. Can I use regular 15w40 diesel oil in the engine? It would actually be wolfs head semi synthetic 15w40 I would put in the engine since that's what we have in a drum and put in all the other diesels. Also was thinking the oil used should have zinc in for the engine? Can I use regular 80w90 in the trans? I see a lot of people say use the same oil in the rear and trans but nothing I've found is clear as what to use and nothing specifies if they have the actual hydraulic lines for live hydraulics. I would think hydraulic fluid would go in the rear then but I'm no expert that's why I came here to see. I got it running and the loader works, 3pt arms go up and down, pto engages and in that amount of time blew a hydraulic fitting on the loader, blew a rad hose and had oil leaking out of the front seal. So what I am asking is what oil goes in the engine, trans, rear and the loader hydraulics. The answers may seem obvious but I want to be sure since I see things saying the seals are sensitive to different oils and don't really want to tear it apart to replace seals too right away. Thanks for your time.
