hi we have a js 130 2008,last week the l/h track forward stopped working(new motor fitted june last year) , well slowed down , now it has stopped , reverse ok r/h track is normal .any ideas thank you
Check for contamination in the oil, Pressure check , Try swapping the main hoses around at the motor just to see if it swaps the fault in the other direction as this will be simple to get at for now as this will prove motor or further up stream rotary coupling,spool ,servo circuit fault.
servo fault now on screen
Try swapping the servo lines at the valve block on the l/h track spool or put a guage in the servo hose at the spool and check pressure and work you way back to servo pedal for tracking.
reverse tracking will speed up if the dipper is on load + it tracks out of line
