3600 hydraulic pump on a 3000?

Comparing the 3600 to the 3000 I noticed the 3600 hydraulic pump has quite a bit higher GPM spec. The loader on my 3000 is ran from the tractor pump and wondering what the feasibility is of installing a 3600 pump on the 3000. First I thought about moving the loader over to my 3600 but that would be a major operation.

Thoughts?
 
Your 3000's piston pump is rated at 5.3 gpm. The 3600 piston pump is rated at 5.6 gpm, which is only a 5% increase. The 3600 gear pump is rated a bit more, 7.1 gpm at 1800 rpm's, which is where the 3000 would be running at, so that would be about a 33% increase. Lots of replacement gear pumps advertise 9.5 gpm, but that is at 2400 rpm and the 3000 engine is governed at around 2200, so even if you ran it at wide open throttle you would probably only be getting around 8.5 to 9.0 gpm.

If you go with the gear pump you'll have to make up your own lines, as the locations of the fittings on the pump won't work with the original lines, and you can't just use the lines from a 3600 as the pressure line on the 3600 is plumbed into the bottom of the center housing where on the 3000 it goes into the side.

It can be done and it will increase the speed of the loader incrementally, but for the expense and effort required I would switch the loader to a front mount pump driven off of the crankshaft pulley and leave the 3 point hydraulics as they are. The front pumps are generally in the 12 to 14 gpm range which is more than double the flow of what is powering it now.
 
Not to contradict Sean but I thought the gear pump was one of the upgrades that came on all the 3600s.
I had an early 3600D, built 11/75 (still had an oil bath air cleaner) and it had a gear pump and twin lift handles on it.
And I 'thought' the 3000 piston pumps put out about 4.4 gpm while the 3600 gear pumps were right at double that ~ 8.8 gpm.
I asked about putting the hi vol gear pump on a 3000 once and IIRC the brain trust here suggested the internal lines and porting in a 3000 would restrict the flow and potentially create excessive heat in the system.
But I do not know myself and would welcome another conversation on that subject.
As for changing the lines, I went the other way with it once.
When I installed a 3600 trans/rear end on my 3000 I continued to use the 3000 pump.
I had to make changes to the lines which was pretty easy to do with parts from a local hyd shop. Ran it that way for a couple of years till the pump failed and then replaced the whole shebang - pump, lines, etc with the correct parts for a 3600.
 
Tractor data says 8.5 GPM for the 3600 and 5 GPM for the 3000 but probably a silly idea anyway.

The loader is a little slow but has been adequate for my needs, hasn't been worth going to a front pump with the expense and trouble of new lines and a holding tank. Am sure the tank built into the frame of my loader is a rusty mess.

If I get ambitious maybe one of these days I'll just move the loader over to the 3600. Everything is a project, before moving the loader I would feel better if I completely rebuilt the front end of the 3600 which could be another can of worms.

I really like these old Fords but one has to be willing to twist a wrench and deal with challenges.
 
Ultradog, I'm not sure on which particular models they used them on, but the parts site shows both a piston pump like the earlier 3000's had and an engine mounted gear pump for the 3600.
 
Did the piston pump ever have the screw on filter, thought all the piston pump tractors had the filters buried under the lift cover and the external filter came about when they changed to the gear pump.

That is correct, the piston pumps never had a spin-on filter the way that the engine mounted gear pumps did.
