unimog hydraulics

[eddiegts]

I know I am being really dense. But on the back of my mog I've got 4 pugs to attach hydraulic pipes I plugged in my timber trailer to the both sets and on one of the sets all I could do with the trailer is lower the legs and the other nowt! When it's plugged in what do I do with the leaver in the cab? Do I need to have one pipe plugged in one connection on each bank? If that makes sense

Not sure about mogs but if you have a valve block on the trailer then the connections required fill be flow and return and the lever inside set to continuous pump.

Fill a volvic bottle half full of water, then jam it between the seat to jam the lever on.

If you have an air seat, and you have to jam it against that 1, it will most probably pop out when the seat rises when you stop leaning on it to jam said bottle.

You need both pipes in, 1 is a return, 1 is an out.

Once you have them Sussex, mark them with colour coded tape.

Hehe, I used to use a Vimto bottle

[Stephen Blair]

I have diluting vimto in it.

I've plugged them in every way possible but still no joy I used a bit of rope to keep the leaver on but all I could do was lower the legs and the crane arm! I've always used the trailer with a power pack and it worked fine so do I need to do something with the valve block on the trailer?? The log splitter works fine on the back so I know oil getting there also the tipping ram works there is a lever at the back to change it over from the tipping ram to the pipes and I've turned this.

May just not have enough flow to run the crane.

[eddiegts]

It's a only little and a crap power pack does it

Do I need to do some thing to the valve block?

Sometimes putting oil the wrong way into the valve block can blow out all the seals so nowt will work whatever you do. Test it on the power pack and work out flow direction. On the mog use a tipping trailer plugged in to work out which pipe works on which lever and often mogs have a free flow return that gos back to the tank bypassing the valve block, if it has 1 use it as it help keep back presure down, on the levers in the cab do you have a red collar above the rubber gaiter, some pull up some down to lock the lever in any 1 off its positions.

first, how many levers in the cab, 1, 2, 3, or 4, does your mog have a three point linkage, does it have a tipper, , you say you have 4 plugs on the back, this says to me you have 2 circuits, there is a feed and return in each, normally the tipper uses 2 of these, but you say youve moved the lever to switch the tipper ram out of the circuit. you should have more than enough flow for your trailer, you say its putting the legs down so it sounds like you have placed the lines in correctly, is there enough oil in the tank, are the rpm's set high enough to get maximum flow( can you borrow a flow gauge and a pressure gauge and check ). its just unfortunate your at the other end of the country or we could soon have had you working
