Hello Im looking for some help trouble shooting a hydraulic fault on a 140M serial B9D00843,
The issue I have is the all hydraulic functions operate perfect when the grader is first started cold for around 15 minutes
then all of the functions associated with the Front Valve bank (above front axle) start to slow down, while the functions that run of the rear valve bank (in front of cabin) remain at the same speed, I have been using the blade slide ram as go to for cycle times, when the machine is first started it seems to cycle in 8 seconds (full in to full out at idle) after about 15 minutes this can be up to 25 seconds or more, But if I turn the grader off and then restart after 30secs is will cycle back at 8 seconds and then proceed to slow down again after 1 - 3 minutes
It is the same on all functions on the front valve bank, wheel lean, blade lean , blade rotation, blade slide etc
Loading other functions doesnt seem to make a difference
Any ideas ?
Im guessing it will have a priority feed to the main functions ? Steering & blade lower etc ?
Thanks any help would be great - Jason
