7745 lift dropping

WOW! Seems like a lot of sludge. I found a few specks of metal too. Pulled them out with a magnet. Maybe filings from manufacture? Maybe something else. Time will tell. Thx Foxman

your lift problem may come from a worn out o ring in the main pump assembly. Take of the cover wich the hydraulic pump is fitted to. its located above the hitc under the gearbox. on the cover its a little pipe that goes into a hole in the gearbox. around that pipe its supposed to be a o ring seal. if thats broken you could get the lift dropping and raaising itself under operation. also it could be the assisting piston seals. the o ring seal was a known problem here in norway at least. any thoughts renze ?
