MF 203 FEL pump drive?

[Viperking]

I bought a 203 with a FEL, but no hydraulic pump to power it. It came with a parts manual and a few handwritten notes. There’s a note that says Cessna 20644-ICEH and another that says Hydreco 24 GPM #708-522-M91 . I can’t find any of those pumps available.
So, what modern hydraulic pump can fit on the 203 for a 200 loader?

If you have some time Monday I will call my agco parts man
He's been around as long as those amd has some used stuff laying around never know he might have something
Other thing is measure flange and pump drive and call a hydraulic shop should be a key way on pump drive they can hook you up

I’d appreciate that. Looks like the pump drive is 3/4”, and flange holes are 4 3/16” center to center.

Check the measurements, it looks like the pump this site sells will fit.

Front mounted pump

It does, but 2 questions. Am I standing in front of the tractor looking at the grill, or on the seat to determine engine rotation? If the former it’s clockwise.
How fast will 14 GPM move the loader? I don’t want it to be slow, but not so fast it launches the load

 

[Jim.ME]

That should be about the same as the original for GPM. What model loader? The pump would be in the loader parts book, not the tractor parts book, so you need the loader model to find the OEM pump part number.

Setting in the seat the motor turns to the left (counterclockwise). So, you need a pump that turns left when you look at the shaft.

Ok, so it’s going the right way.
Here is a photo of what’s in the manual. I’m assuming the thing on the right side is a filter?

Pump and filter as the caption says.

The 24_GPM pump you mention was most likely the option when the tractor had a loader and a backhoe.

Do you know what part number is for the filter, or what modern filter assembly will work? That info is not included in the manual

Need the loader model number to get the right parts book.

It’s a 200 loader, exactly as pictured. There are 2 different 200 models in the binder for some reason.

It looks like it maybe 671163M91 filter assembly.

It looks like it’s no longer made. But once I have the pump in hand, could I use adapters to route the oil to a modern filter assembly?

Yes. You will need a filter for suction side service, not return. It needs to be rated for more than the pump GPM. Finding the micron rating of the old filter would be a plus

Easy enough. Could I get a filter that’s lower than the original micron rating?

 

[stevieb49829]

What Jim is saying, I think, is that if you change to a different filter, just make sure the micron rating is at a high enough flow level to be more than the pump output. Too small microns will restrict flow, and that's not good for a pump searching for oil to pump. Microns are the size of the particles the filter will trap and let smaller ones through. 10 is a tighter filter than 25. The filter should spec both the micron size, and the flow rate. steve

Almost any aftermarket filter head that will accommodate an appropriate filter and fit somewhere convenient to plumb it and change cartridges will work.

This is a screen better than a filter just my two cents worth

My 102 loader (very similar to your 200) lists 17 GPM@ 2000 RPM, 2150 psi.

The tractor uses a SAE "A" type mount. Any SAE A pump with a 3/4 shaft and CCW rotation will work.

The pump/ spool will dictate filter microns. 25 micron is standard. If you put the filter on the suction line, you need an 1 1/4" filter housing. Zinga SE 25? It's listed for suction. Below is a picture of mine.

That is an in-tank Return flow filter, it will not work for him. That filter unit needs a hole in the reservoir for the black part to fit in. The black bottom housing has to be inside the reservoir as the stub at the bottom is the outlet. And it uses a replacement element, not a screen.
