So for anyone that saw my other post "T250 problems". I bought a machine cheap at auction that pretty much all of the hyd system was toast. Short answer, we had both drive motors rebuilt, tandom drive rebuilt, and a new gear pump. Took apart the lift block and cleaned, cleaned the tank, washed out and cleaned every hose in the system and just finished putting everything back together. So, backed the machine out of the garage for the first time, it ran great for about 90' and then started to slowly die. First I noticed the machine would not spin in a 360. It would try to stall the engine. Took it onto some soft dirt and lost all pull from the right side drive motor. Left side seems to pull good but right has almost no response from the crontrols. Got a warning light over head diamond with ! In it. Says general warning. Then got a warning for low charge pressure. Last got a code 35-02 for the 2 speed fan motor. Thats as far as I got. Discusted with this project for the day I just left it there in the dirt and went home. Any ideas, even "light it on fire" is not out of the question at this point.
Did you replace the hoses or at least flush them out
Yes. Washed out and cleaned every hose
The engine pulling down is probably fuel supply. But the lack of drive on the one side is probably something assembled wrong
typically a very low hour failure combined with the low charge pressure is due to a "dry" startup. the tank sits low in the frame, lower than the pumps. we overfill the tank, and let the machine sit ( usually overnight) before the 1st startup. start and idle the machine while monitoring charge pressure. low charge and we shut the machine down you may also find a piece of debris stuck in the charge relief valve on the pump holding the valve off the seat.
