I just bought a MF101 industrial loader for a good price, to go on my MF165. I want to replace the controls as they appear to be in bad shape and would like some input before I go to a hydraulic shop blindly. Is it common to replace the controls with standard valves available on the market? And also what is the purpose of the hyd. fluid reserve on the loader itself as this will not be used if I replace the controls with a commonly available controls. Any help appreciated.

You will be very disappointed with your loader if you use the existing tractor hydraulics and pump,they are just too slow, get a front mounted pump with its own reservior with plenty of GPM and you will have an effecient machine.

Those guys at the parts store are going to strap you over the barrel. Grin and bear it.

keep in mind that if you use the tractors hyd system the volume of fluid in the cyl& lines must be considered as you could starve or over fill you tractors system.(if your tractor uses its tranny as a resavior,4 large cyl on a loader fully extended could rob enough fluid from the tranny to be a problem,on the other hand this much fluid added to the system may cause a over full senario with all cyl retracted.)I hope i expressed this clearly as your senario may or may not have this problem,do keep it in mind.

I think the 'stock' MF 165 hydraulic pump output is something along the lines of 4.4 GPM.. by comparision, my JD Industrial Backhoe pump is rated for 26 GPM.

I think that this is the reason that most MF's with loaders that I've seen of that vintage run auxillary hydraulic pumps off the front of the crankshaft.

I think it's gonna be one slow puppy running off the stock pump.

What's your intended usage ? Occasional light duty or regular 'production' work ?

Did the loader have a front mount pump, or a pto pump? And you are planning on running the loader off your tractor hydraulics now? I don't quite understand.

If you are using your tractor's hydraulics you won't need new controls. If you are just replacing the controls, you will still be using the self-contained pump & tank. You need an oil reserve.

Where exactly do you want to end up with this?

the 101 and 200 loaders both had an independent pump that ran off the crank shaft.i'm gathering that you want to change the controls to maybe a joy stick.the loader frame oil tank was needed since the loader used that type of pump.i have a 200 on a 601 work master.good luck

Thanks for the info. This loader did not come with any pump, I was told I could hook it up directly to my tractor hydraulics, and if I do hook it directly to the tractor hyd. will I need the reserve in the loader? Also I would like to replace the controls because the handles are broken and it appears it leaks hyd. fluid. How do you run the loader on your workmaster. Thanks for any help as can be seen I need it.

oh the guy at the parts counter is gonna luve you when your standing in front of him. Your gonna walk out with half the store if your not carful.

id suggest you sit down and think a little more about this, make a few trips to tractor dealers look at a few tractors with loaders, see how they are setup, might help you understand a little better.

Hydraulic controls are of the following types, closed center[constant pressure], power beyond[for connecting to another control or other use] and open center[fluid flows through until lever is moved] this type is used on most loaders. Controls are cofigured for single acting cyls, double acting and be made any combo you desire. Not knowing what hyd that your tractor has a front pump using the built in res might be the easiest way to go. Pumps must pump 10-14 GPM and turn CCW. I've looked on ebay and not enough info is availabe to warrant a chance. There are plenty of surplus stuff around, I get most of my stuff from Surplus Center, Lincoln Ne. Hope ths helps a little, Jake

Ok, I'm a hydraulics dummy myself, so there will be some corrections to what I say....

To run the loader, you need a pump, some controls, an oil resivor, the cylinders on the loader, and pipe/hose to connect it all together.

Some loaders have just single acting cylinders (one hose, push one way, gravity pulls them back together) to lift the loader, & a rope to trip it. Some have double acting cylinders to both lift/lower the loader, and to tilt the bucket.

Your controls will need to match the way your loader is set up.

You can use EITHER: The external pump, resivor on the loader, and the controls on the loader:

OR you can use your tractor resivor, pump, and built-in tractor controls.

You can't really mix and match, so don't go buying loader controls until you figure out what pump & controls your tractor already has....

So, I'm not familiar with your tractor. What does it have for hydraulics? Does it have 2 levers/ ports? Are they double acting? Do you have live hydraulics on your tractor? (It's much more frustrating to use a loader on a tractor without live hydraulics - every time you push in the clutch, the bucket won't move... Might be an incentive to buy a front pump...)

So, you might need to buy new controls for your tractor if you don't have the right ones now.

You might want to just buy a pto or front-mount pump and new controls for your loader.

But, as the other guy says, figure out where you are headed and if you can get there from here before you walk in & get a lot of parts dumped on you.

If you don't understand some of the terms I used, try looking it up in a search here in the archives. Lots of good help on this over the years. And of course, ask away here. :)
