water in hydrolics

[mffarmall]

I'm not going to keep it for a long time but just like how it cleaned everything out. I'll go back soon. Where can you get 90% alc, do you mean the good stuff or a petrolium based one?

Changed out the diesel and got a good lift out of it. Might look at keeping it in? Could the hyp pump burn out with such a light mix?

You could probably get a lift with water. Temporarily anyway, until the pump burned out.

Besides being thinner, the diesel fuel doesn't have the lube properties of hydraulic fluid. And I'm pretty sure AW32 will be more seal and hose friendly too.

Isopropyl alcohol - like rubbing alcohol. It is typically bottled as general purpose (70%), strong (90%), or straight (99+%). Cheapest way to get it is by the gallon from vet supply houses.

diesel does clean out the system well. With regular THF and some sea foam this should be a done deal. I will probably change it again in the spring.

Since your tractor has separate sumps, you should be using separate fluids. Universal fluids like THF are for common sump systems where tranny/diff and hydraulics all share the same fluid. On your machine THF will likely be too thick for hydraulics, too thin for gears. You will get majority recommendations here to use gear oil for the transmission and differentials, hydraulic fluid for the hydraulics.

That sounds good to me. Hyd is cheeper anyway.

THF for the dif or a 30 w?

Neither. Like I said, gear oil for gears - hydraulic fluid for hydraulics.

Transmission/rear diff - typically 80@90 non-foaming yellow metal friendly gear oil. 85W140 in warm to hot climates
Hydraulics and steering - typically AW32 hydraulic fluid. AW46 or AW64 in warmer climates. Be careful to buy AW-- hydraulic fluid and not AW-- machine oil. Not R&O oil either, for that matter.

Like Greg said

Use something like 80W90 for the gear box and AW32 for the hydros in your area. Some in hotter climates like Greg use something a little different but you really cant go wrong with the 80W90 and AW32.

Some Walmarts now are carrying their brand ( supertech ) of 80w90 oil with anti-foam and yellow metal saft labels.

Also, some pharmacies sell the 90% alcohol in as large as 1g jugs.

That sounds good to me. And the most important item from all of this. Don't leave hyd outside... Or water will get in.

I finished up changing out my hydrolics and everything seems to be back in action.
