Something I want to discuss at the rally as well.
Did anybody ever modified the M51 dump hydraulic system to make it multifunctional?
Moving the pump and reservoir
On the M51, the hydraulic pump is driven by the rear PTO. It is connected to the subframe, same as the reservoir and the dump cylinders. The pump actually sticks out below the main frame. Nice if you never take of the dumb bed but a horror if you want to have a multifunctional truck. So my idea is to keep the locations more or less identical but fix both the pump and the reservoir to the main frame. Then, it is easier to take the subframe off and I keep the hydraulic power system available when in "tractor mode". Anybody ever did this or thought about it?
Multifunctional pump
Dump hydraulics pump powers dump trailer and other hydraulic applications. It means that the pump will get quick-release adapters so we can disconnect the main dump or switch a lever and power a dump trailer or suspension legs (to lift the wheels of the ground) etc etc. Anybody ever thought about that?
Dump trailer
To my big surprise, most of the old farming tractors trailers here (up to 15 000 lbs loading capacity) have two single-system cylinders - on in the front and one in the back - making the trailer a side dumper for either left or right (not rear). My son actually has a small one and I can get a bigger size for peanuts. These trailers are normally powered by the tractor hydraulics; they do not have their own pump or reservoir. Could I borrow such a farm dump trailer and run it off the adapted M51 system or does the mixing of oils cause problems. If the latter, we would have to buy one especially for the M51, which is not very cost effective.
