so your problem is that it continues to go down not that it goes down fast?

drop speed is as it always has been?
dump doesnt close when you let go of switch?
but you can still lift again next time?


sounds like dirt in the pilot hole or a seal picking up.........
new seals and a blow out with an air line.

first off, what kind of dumps are they? what oil are you running in your pumps? and what is the temperature??? sometimes, if you have too heavy of an oil, when it gets cold, the dumps start acting just like yours are...

I have a feeling it might be what VegasHopper is talking about...i use 40 weight ND oil....and the weather has gotten alot colder now.....whats the best oil to use in cold weather?? Can I go with the thinnest weight of oil?? Ima take the dumps apart n clean em with an air hose and check all the seals too...just in case...oh BTW they are steel square dumps. Thanks for the help everyone!

ATF-3 works really good year 'round and especially in the cold. I've been rolling with it since '91 from New Hampshire winters to Florida summers. :thumbsup:

ATF-3 is different from regular transmission fluids because it doesn't contain the detergents that CAN actually be a problem for pump gears.

ATF-3 isnt that like dextron/merconIII or is it something else? What brand do u get n where do you buy it?
I usually pick up Havoline but it doesn't matter, as long as it's ATF-3. Big-name or no-name, it's pretty much the same, especially since we're not putting any real "wear" on the fluid and only using it in a pressure application.

Dextron has detergents in it. Which isn't very good for pump gears. The detergents foam easily and this foaming cavitates the pump. Cavitation in this case meaning that not only fluid is going through the gears. The foam "bubbles" are also transferred and basically, it's not good for those bubbles to be "smashing" up against your gears. So tranny fluid, which actully IS hydraulic fluid (ask the old pros, and recognize the term "hydraulic transmission") is OK to use, as long as you use the right type. ATF-3 is non-detergent.
