2600 hyd pump fit a 2000?

This may be a dumb question, but will a hyd pump off a 2600 work on a 2000. The external filter would be nice to have.
Thank you.
 
The pump would work, but you would need to make up custom lines to go between the pump and the rear axle center housing. The lines from a 2000 would be incorrect at the pump end, and the lines from a 2600 would be incorrect at the rear end.
 

It ll mount on but the pipe connections are different, you ll have to modify the pipes to make it work
I found some piping from a salvage 2810 to make the connections, the increased pump flow is nice
 
Is a 2000 gonna have the cam gear to drive the pump, or is this going to become a tractor split?
 
I double checked the parts drawings, and the current part number for the gear on the camshaft that drives the pump is the same on both models. I checked because I was wondering if they might have changed the number of gear teeth, but it looks like they did not.
 
I went the other way once. Grafted the back half of a 3600 onto my 3000 and used the 3000 piston pump. The pressure and return lines were not at all difficult to contrive. The pump was a direct swap - gear, gasket, etc.
New Holland sells 2 different filters for the gear pump - short and long.
If you have horizontal exhaust you Must use the short filter. If vertical exhaust it doesnt matter.
Eventually I found a good used 3600 gear pump and correct lines for it. Still running them.
But a question I have asked about here before and never got an answer to is:
The original 2/3000 piston pump puts out about 4.4 GPM.
The later 26/3600 pump puts out double that amount.
What effects can doubling the flow cause in a hydraulic system not designed to accomodate it?

If things are properly configured with a relief valve, then there is no threat of over-pressuring, but if there are passages that are not large enough to allow for the extra flow, then the fluid could run hotter than initially intended. If you monitor the fluid temperature during an extended workout of the tractor's hydraulics and it stays below 180 degrees then no real damage will be done. If the fluid temps go above 180, then the fluid will break down sooner and need replacing. With a 2600/3600 pump on a 3000 hydraulics system, you could use the flow control valve to reduce the flow, but on a 2000 there is no flow control valve, so that is not an option in that case.
