My first time on so excuse me if I make errors.
Have a 1989 ls2800c 11 I have been operating for several months and has been operating perfectly. Now all of a sudden the right track runs super fast and the hydraulic system seems to be fighting itself-pulling down the motor-swiing,boom,etc.,all pull the engine down-eventually the motor gets hot from lugging. I think there might be a actuater valve or control valve open or closed or a broken wire to one of them? Also have never had any hydraulic seeps but now have several joints weeping like extreme pressure from by pass not working right or something yet the unit doesn't have much digging power. Any ideas as to where I could start checking? All filters have been changed a few hundred hours ago-oil looks great and is full. Would also love to get hold of a service manual.
Thank you
