MF 245 Paired with Wood 1020

[NCAlaskan]

Hoping someone can help me with two things:
1. What size hydraulic pump I need
2. Where I can buy one that will bolt on to factory holes

The tractor is a 1979 MF 245. The loader is a Woods 1020 (pretty heavy).
I want to mount a front pump as the between the legs pto switched line is not enough to pick up much at all. The prior owner was trying a PTO mount pump and it blew the line during the test drive when I was buying it.
Can anyone speak to the size pump you would recommend for lifting the Woods 1020 and a load? I have a reservoir and can handle hoses, etc.
Attached are pictures of the front mount. Can anyone recommend a make/model/solid supplier. I have contacted some already and not found help.

Hi. Welcome.

Hopefully someone on here is familiar with your tractor and can recommend a solution.

Thanks! I hope so.

The internal hydraulics should make plenty enough pressure to lift it but would be slow. Most MF industrial loaders used a 17 GPM pump but I think for a farm loader something around 12 GPM would be fine with a 2000-2500 psi relief valve. An MF dealer should have the pulley, shaft and coupler for mounting a front pump. A&I or another aftermarket parts supplier may have them as well. A good hydraulic shop should be able match a pump to fit the holes and coupler.

You may find a pump on surpluscenter.com, like above 17-25 gpm should be fine. You could make an adapter plate if you have to.

25 GPM would be too fast and likely require high flow spool valves.

The pump only produces it's maximum output at maximum rpm, given that situation the oil only has to pass through the valve, the operator selects how much to pull the control lever. I think you may be speculating.

I have a Cat track loader with a backhoe with much bigger cylinders and it has a 26.5 GPM pump. I was looking at making a scarifier to fit on the back in place of the backhoe but would need a high flow control valve to handle that much GPM. Having too small of valve for the flow will result in heat build up. Having too fast of a pump can be more trouble than it's worth when you have to be barely moving the spool valve to avoid jerky hydraulics and can also be dangerous with an inexperienced operator. Consider that most smaller farm loaders don't have self levelling buckets. If the hydraulics are super fast you could lift the bucket up and dump the load in your lap before you knew what happened. A reasonably sized pump would give you much better control. It's better to run the tractor at a higher RPM than to be idling it and having to baby the control valve. There's also times where the tractor will be at 3/4 or full throttle for other tasks and with a front pump the oil is continuously pumped.

I have had many types of loaders, backhoes and dozers too, I was in the sight work business for 35 years, I also build many specialized hydraulic machines, but I do not know what size valve or feed and return lines are on his machine, so, the information I supplied would need to to be verifed on the job or by way of more information than was provided. Those numbers are a range not an absolute. Maybe you know what exactly he has, I have not seen that information. When you say high flow that is relative. I had some loaders with 50 gpm pumps. That would make many machines low flow. Correctly sized valve and pump would be the correct way to do the job.
What I did find is that the Woods 1020 had 3/4" lines in and out.

Yes, correct sized pump and valve. 25 gpm would also require a larger reservoir. The industrial tractor loaders also used heavier duty components than a farm loader. If you try to use a farm loader like an industrial loader you're asking for trouble. I think a pump in the 12-15 gpm range would be ideal. 25 gpm would be serious overkill and require everything else to also be bigger. High flow is relative but I didn't pick a number out of thin air. I based it on what the industrial version of the same tractor(MF20C) with factory loader came with, a 17 gpm pump.
