I've got a 2040 diesel the loader is very slow and doesn't have a lot of lifting power. I've told the Surge pump is bad what's the best way to pull it an how is it to fix ?
 
IMHO, your tractor does not have a "surge pump" nor does any other DEERE tractor that I am aware of.

Time to get some help from a knowledgeable source and/or buy a technical manual and go through the official troubleshooting procedure to figure out what is actually wrong.

Of course, you might start buy checking the oil level and changing the filter and checking the sumo screen.

How long since hyd filter was changed and sump screen checked/cleaned?

What's your tractor's SN as 2040 hyd's could be either open or closed center? Does your tractor have a 3 or 4 cyl engine?
 
It has a "charge pump" that feeds the "main pump." If the charge pump was not sending enough oil to the main pump, it would starve for oil and jerk around alot. Not run smooth but have low power.
 

As previously asked, which 2040? How is the loader's hydraulics plumbed into the tractor's hydraulics?
Is the problem new ? Suddenly occured or gradual? How cold is the weather ?
 
It has done it since I got it. It is a German Deere. Charge pump is what was meaning when I said surge pump my mistake. I've had the tractor since June. I'm pretty sure the charge pump is bad or weak what is the best way to change it an how much is a pump?
 
(quoted from post at 13:18:03 02/02/15) I changed the filters an fluid an filter this past summer it didn't fix anything

We need some pictures . Did you check the transmission screen? If the wrong valves are installed and/or connected incorrectly, this will make the loader slow and noisy.
If made in Germany this tractor should be a four cylinder diesel with closed center hydraulic system iirc.
