the right track loader keep turning .when you let go of joystick.when you put it in reverse the right track still turn.unless you turn idle down the the track will work normal for a littlebit
Your right hand travel pump swash plate is sticking over,this happens when the roller bearings mark the swash plate with small indentations and the rollers stick in the indentations, no easy cure, you have to repair or replace the pump, Liebherr used to have repair kits but don't know if they are still available, bad news number two is that the other travel pump will probably need doing too if it's done the same hours.
do you work on the liebherr.and where you find info
Not anymore but I worked as service tech up to service manager for twenty two years with Liebherr
just a suggestion I would check to make shure that the plunger under the joystick is not partially sticking down a little bit I have had that happen on excavators before
Your pump is probably screwed . There are 2 clips inside the pump that keep the cradle bearing and the swash plate located correctly. These clips will wear thin and break keeping the swash plate from returning to the correct spot. If this is the case; the cradle bearing can come out of place and get in the rotating parts of the pump. If that happens you will have a destroyed pump and a contaminated system. Good luck.
