after around 30min of work backhoe stops shifting forward gears and only revers works. It lights up dash signal (photo attached). Thank you for your help !
Brake proportioning valve maybe?
Maybe you can give me idea about its location and how to check it ?
Just guessing ,I have never seen one of these machines Start at brake pedal and follow the lines where they go see what you find
Thank you ! You have seen machine with same problem ? No forward only reverse after heating up ? Maybe you know how this valve works ?
Check the oil level in the transmission. Change the transmission oil filter. Carefully cut the filter open and look for metal in it. Unless it has a screen and no paper filter.
Thank you very much for your suggestions!
light for low brake pressure? steering and brakes are likely on a priority circuit before anything else in the hydraulic system. its a safety feature
might also be combined with a pressure-reducing valve( or valves) for the steering and brake circuits
Update We repaired automatic transmission hydraulic pump, now everything is great with driving forward and gear shifting but it is leak of power. We checked everything around engine from turbo to diesel pump, everything is great but engine provides only 1500rpm and has low power. Strange thing is that power increases when driving forward and using any hydraulics with joysticks... another problem we found is burnt sensor that is in the photo and i cant find it anywhere. Model of machine is NH ft110 of fiatallis ft110 I think i found part in messicks https://www.messicks.com/nh/317377?sectionId=24224&diagramId=317377_676874 Numer 13 but they replayed me tkat they dont have it in stock. (Email attached) Question: can the problem with power couse that sensor ? if anyone of u can help me with info or parts or smth, please !!!
