JD 230 LC will swing about halfway, then stop. It will get stuck and you will have to work the swing control left and right several times to get it to swing back the other way. You can feel it trying to move when it gets stuck and it will eventually swing back. When it does swing, it doesn't swing like it should it kinda growls. Did not make any loud sounds when this happened like a tooth breaking off the swing gear or anything.
Start with checking the grease tray for ICE. gear box for oil.
Swing gear is to the full mark on oil. Actually ran machine for a few hours before problem occurred.
What is the inlet pressure and the release pressure when it is trying to swing?
swing break. check you pressure going to the swing break when trying to swing. when you start to swing it should release by putting pressure to it. if so then you cant test by putting a port a power and pressuring up the swing brake piston on the motor. to see if it leaks down. if it does then your seals are no good on the piston for the brake
Today, I swung it around at least 100 times. Did not stall at all.
