That's a good question. Some people suggest the same oil you put in the engine incase they mix, but I use hydraulic fluid. Before you replace the pump though get your hands on a rebuild kit and replace all the seals as that may fix your problem (assuming the problem is that it's leaking). This aftermarket pump I have is not as well built and new holland doesn't make them anymore.

If it's the same one I referenced in the video then you know that I didn't bother to locate a new one and just used the old one. But just call your local New Holland parts department and I'm sure they can locate one for you.

Yes and yes.

@@FatChanceFarmstead ok last question on the opposite side of the tractor in front of the fuel pump...what is that. And does it takes hydraulic fluid. I took the top off and it has gears inside

@@johnrobinson2074 I'd need to see a picture as there were a few different injector pumps fitted onto these tractors. One type requires oil.

Hey Ed, got this on Ebay from Georgia. It's an aftermarket, not gonna last aslong as the original from what i can tell. I kept my old one incase this one doesnt last and may try and rebuild it.

Not sure what you mean. But the loader has been on the tractor for maybe 5 years.

@@FatChanceFarmstead is the front axle strong enough for loader work? I'm thinking to install a loader in my Ford 6600

@@parchechuletaovero9507 aaah I see. Yes it is strong enough for some work but I wouldn't be moving heavy loads of sand or gravel over and over. If your 6600 is 4x4 that's a different story but those 2 wheel drive tractors arent built for heavy lifting. Make sure those front wheel bearings are tight. Goodluck.
