Sudden MF188 hydraulics problems

Fredrik Malm I have a MF188 with MP, when working with snow "thrower" attached to PTO for 6h it suddenly lacked power - aslo lift arms and MP stopped working at the same time. We have -15...20deg C here in Finland, so I tried to add some antifreeze (spirit) to gearbox oil, filled up 10l of oil (was low)and also put a fire(!) under the rear housing - no help. After some hours of trying, lift arms get up slowly but with a lot of air first in cylinder (flexing arms), comes up in periods but takes ca5 minutes. PTO is always turning, but no real power in either on/off position.
Is my pump OK, maybe only filter clogged/frozen? Read about o-ring seal of pump suction line off position, could this be the case? How can I access the filter and pump suction 0-ring seal(s), have no manuals so far... /Fredrik

fredrik I got some god advise and have worked on this problem as follows:

1. The problem was localized to the double clutch, which I changed. This didnīt solve the problem...

2. Second guess was clogged filter, not easy to access but I managed to do that also with some telephone help from a almost retired Fergusson professional... this solved the hydraulical problems!

3. Still have one problem, the PTO seems to work on/off but power is poor, the Fergusson expert now thinks that the "PTO clutch" inside gearcase (under pump) is worn out, to access this I would have to tear the tractor into peaces (back part away from gearbox) !!! Any other ideas of where the problem could be?
