Ford 2000 loader fluid demand

I have a question about loaders. I have
never had a tractor with a loader before,
so I am curious about fluid levels in the
reservoir when the cylinders are extended.
I have a ford 2000 with a loader, however
when I look at the cylinders and look at
the size of the hydraulic reservoir it
seems that ALOT of fluid will be in the
cylinders when extended- so will my final
drive be starving for oil? Or is there
more than enough fluid?

Fluid level will drop a little when the cylinders are extended, but not as much as you might think. This is because as you extend the cylinders, fluid from the rod end of the cylinders are returned to sump. This means that the difference is the volume of the rod itself (x 2 of course), which is really not all that much oil.

Even if it was a lot of oil, how often do you drive a long distance with the loader up in the air?
 
Okay, that sounds logical. Thanks for responding, it was one of those thoughts that I had when I was looking at my loader. Since it was off a different machine it has a large reservoir inside of its frame. It made me wonder about reservoir sizes and whatnot.
 
I?d agree...if these are DA cylinders. Oregonaaron, do you have one or two hoses connected to each cylinder?

I see only one hose on the cylinder in the pic, and it appears to be connected to a rigid steel line running to the lower end of the cylinder. If I?m correct, these are SA cylinders (or DAs plumbed as SA, with a vent port at the high side). That would mean no return flow as the cylinder is extended.
 
Oregonaaron, if you have single-acting cylinders, you can get an estimate of how much hyd fluid is used at full extension.

Cyl volume = pi x (cyl radius squared) x cyl length.

Then subtract the rod volume from the cyl volume => use the same formula but plug in the rod dimensions.

Multiply the result x 2 (since you have two cylinders).

Then convert the result to gallons. If you?ve worked in inches, then your conversion factor is 1 cubic inch = 0.00433 US gal.

If memory is correct, the sump holds 6-ish gallons.

However...as the other reply very correctly pointed out, you should rarely motor around with the loader raised very much - and not at all if fully lifted, for safety.

If you?ve never run a loader before, it would prob be worth your time to Google for safety tips. These are incredibly useful but can injure, maim, and kill in a flash, all with no conscience. One very very smart guy at work got killed when he got under his loader at home for a few sec to hook a chain and a hose blew out.
 
They sure appear to be double-acting to me. You can clearly see a tube going down to the rod end of the cylinder, which would provide down force.
 
If those are double acting cylinders 2 hoses going to each cylinder with 1 1/2" rod and 40" stroke you are looking at a little over 1/2 gallion loss in the reservoir when raised all the way up.
 
with a double acting cylinder, after cycled a time or two to fill and purge air and then topping off the sump, the level won't change as you are just moving the oil from one side of the piston to the other. There will be a light change taking into account the area taken up by the rod when retracted. On a single acting cylinder you do loose the capacity of the cylinder when raised.
 
Makes no difference. Manual says to check fluid level in the rear with "all cylinders extended". That means raise the 3 point lift to full height plus extend all cylinders on all implements including the loader. Once you do that and fill it to the level check hole, don't open the level check hole without them extended or you'll lose some fluid. That rear end has plenty of extra capacity to be filled above the level check hole once you fill it to that level with all cylinders extended and put the plug back in.
 
Yes DA. Good deal, I guess I could have figured out the answer to this if I would have just thought about it. Thanks for all the responses
