MF 202 front end loader quick disconnect?

I have a question about a more efficient method to remove the loader and pump from a MF 202 Work Bull. I have a 58 MF 202 Work Bull with a front end loader (MF 102), backhoe (MF 85), and 3-pt. hitch. The loader and backhoe are powered by the crankshaft driven hydraulic pump. I can use the 3-pt hitch with the loader on, but it's much better when I remove the loader. Removing the loader isn't that difficult, but it is time consuming for me. One issue is the fact that the front hydraulic pump is connected to the loader frame with 2 hoses (the 1 1/4 supply line and the 1/2Ē high pressure output line). Due to the design, these hoses are both routed through the tractor frame. This means that both need to be disconnected to remove the loader. You have to drain the supply tank and then disconnect hoses. The supply hose is held on at either end with hose clamps and the high pressure hose is threaded on both ends.

Being able to disconnect these hoses using some type of quick disconnect would make this process much easier and not as messy.

Iíve considered quick disconnect hoses. Iím not sure if these would be advisable since a failure could interrupt flow which could be really bad if the pump was operating. Iím also concerned that a quick disconnect on the suction side might restrict flow too much.

Iíve also considered Camlock Fittings with a ball valve on either side. A ball valve could be ďlockedĒ open and with camlocks, I would think that the chance of interrupting flow would be acceptably low.

Can anyone recommend a better method to disconnect these hoses?

Now this is a very interesting idea. The tractor already has a quick disconnect routed between the engine and the dash that goes to the lift cylinder.. There may be another, but I'd have to look to see. I have the book that probably came with the loader. It tells you how to install it, maintain it, troubleshoot and gives specifications. It does not give any instructions on how to remove it. If you can use the disconnects already there then you would need to unpin the 2 lift arms and unbolt the frame pivot points. I'll have to take a look a see what it would take for this to work.

I still would like to be able to remove the loader frame without draining the system if possible. It makes it easy to access every thing on the engine and with power steering very easy to maneuver.

I have a large weight that I can put on the backhoe sills when the backhoe is off. With the weight I can use the loader and still get decent traction.

I really like the idea of getting another, but covered space is tight.

Another thought, if you were to remove the loader arms and bucket all as one unit you could still use the quick disconnect system, unpin the loader arms and the lift cylinders and make something to support it then just back the tractor out of it, the rest of the hydraulic system staying on the tractor. Many modern tractors do it this way, although they were designed to do so. I can take the loader off my Kubota in under 5 minutes.

I agree that using the 3pt with the loader installed is a bit of a pain but is it worth the work to remove it every time you want to use the 3pt. For me I found it so prohibitive, I bought a TO35 to use for 3pt work and left the loader/backhoe tractor in tact.
One thought, when the backhoe is off, you don't get much traction which makes using implements really tough, and forget about using the loader! Would it be simpler to work on a quick disconnect hose system just for the bucket? That way there's less hanging out front and much better balance, hence more traction. You would also be keeping the hydraulic system full of fluid and reducing the risk of it rusting when empty.
