75g slow sometimes

[Newibiner]

This machine some of the time won’t achieve max pump flow, engine performance is fine. Then just like a switch gets flipped and everything is back to normal.
Once everything is back to normal it is fine for the day.

All functions or certain functions? Did it star with certain functions and progress to all functions? Does it happen right after start up, or do you need to run it a while? Have any pressures been checked?

I would suggest pulling both the pilot and hydraulic filters and inspect them for debris.

Happens at start up. Once it returns to normal it’s fine for the day, or week. Swing and the blade operate normally. Just travel and any excavation function are affected.

New filters are on the way. Have not checked pressures.

I suspect a sticking pilot shutoff solenoid valve. That is located above the panel that is underneath the cab.

I cut the filters open and did not find any of the expensive glitter. So that’s good. Pilot pressure is at 600 psi. Pumps pressure is around 4786 with a stalled track.
