Allis FWD 8050 Powershift Issues

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Got a good one for you guys. Tractor quit moving so the powershift was pulled and hauled into the local dealer for a "rebuild". Got it back and installed it in the tractor. Worked for 5 hours then quit again. Dealer wouldn't warranty because they just got the powershift and not the whole tractor so we decided to split it. Found that there was multiple piston seals ripped. Replaced all the seals and reinstalled in the transmission. Its been working for over 50 hours now however its developed a random problem. It will be driving and happens in any range or powershift. It acts like someone shifted the transmission into neutral and it just coasts to a stop. The range and powershift were not moved nor the clutch pressed it will be driving just fine and then coast to a stop. If i mess with the range/powershift it will start going again. Sometimes its 5 minuets and sometimes its 45 minuets. Removed range transmission cover and when it acts up all the range gears stop turning but you can still hear the hum of the clutch drums turning so I'm convinced its in the powershift somewhere. Also when it acts up the steering, brakes, and pto all still work just wont move. All clutch pressures are perfect to spec when it acts up as well. Any ideas are greatly appreciated.
