MF 236 loader Front Mounted Pump

I need advice on which size hydraulic pump to mount on the front of my Massey 175 to operate my 236 loader. I don't have enough history
operating this loader so I'm not sure. I understand that if the aux and lift pumps are combined on the tractor then the total flow is around 12.8
GPM @ 2000 RPM. I was looking at a pump that is 21 GPM @ 2000 RPM but I think that this might be too big and may operate the loader too
fast not to mention the required size of the fluid resivoir. Now I,m looking at a pump that is 15.5 GPM @ 2000 RPM and 12 GPM at 1500 RPM
which is the approximate engine speed that it will likely be operated at most of the time. Does anyone have any advice on how many GPM it
takes to operate a 236 loader with decent speed but not over doing it?
Thanks,
Dave
 
The parts book shows a 17 gpm pump for the 236, the more gpm the faster the loader will work. You could put a 21 gpm pump on it, and its not going to hurt it. The pumps will put out about the same pressure. I wouldn't use less than a 17 gpm pump.
 
Ok, so now comes the question about the fluid resivoir. How many gallons are needed? The loader frame has a small tank built in it but I
estimated it at 5 gallons or less, not nearly enough. I've heard a rule of thumb is 1.5 gallons per GPM, that seems like a lot. Another authority
told me 1 gallon per GPM, that seems more doable. In any event, I think I'll need to build a resivoir to mount on top of the loader cross member
of the tractor to fit between the loader frame and tractor engine/transmission. But again.....how many gallons?
 

I am a newbie but working on hydraulics on my 202. Logic tells me the tank size is related to the amount of fluid used under full extension of cylinders as opposed to the volume of the pump.

Imagine 2 -10 gallon fish tanks one with 100 gph and the other with 1000 gph filtering. In each case the level of the tank would be the same.
 
The 1.5 gallons is largely based on something that is used pretty steady such as a backhoe that is used in construction. They also usually have an oil cooler on them. I'm no expert on hydraulics but have had some training on it. You can get by ok with considerably less if it is not heavily worked. The more it is used continuously and the heavier loads that are lifted the hotter the oil will gat.
 
I'm not familiar with that particular loader, but most later model loaders use the loader frame as a reservoir.
 
Hello. I have a 236 loader on my 265, with a front mount pump. It works great. You want a 17 gpm pump, which is what it's spec'd for. The oil reservoir is in frame pedestal on right hand side and holds 5.3 gallons per the operator manual. The oil needs to meet MF Permatran specs. Cheers
 
Also you can still buy an MF 236 operator's manual from web that shows how to connect front pump and hoses,etc.. good luck

You are running a 17 GPM pump off of a 5.3 gallon resivoir?..........Wow! Do you ever have any issues with the fluid getting hot? No problems with aireation of fluid either?
I decided to use the 21 GPM pump that I have but may put an auxiliary resivoir on just for safety.
Thanks
 
No problems. The 236 loader was factory designed to allow use with 17 gpm front pump and the 5.3 gallon reservoir in frame pedestal on right side.
