Hi,

I have a Shibaura D23 and the hydraulics become jerky.

I live in Austraila and does not have and isuses of being cold. Running air temp is between 20 to 30dec.

This is the background so far:

Problem:
1: Start tractor from cold and the hydraulics work fine this includes the PTO and the front bucket
2: After 20-30 minutes the hydraulics light comes on
3: After 60-90 minutes the hydraulics start to become jerky
4: After 2 hours the hydraulics stop or almost stop working
5: If you stop using the tractor for a long period (overnight) the cycle then starts over.

What we have done so far to try and fix it:
1: Changed the hydraulic oil
2: Checked the hydraulic filter and changed it for a new one.
3: Checked and cleaned the screen filter/suction screen (which was not dirty)

None of these have fixed the problem.

I hope someone can provide some information on where to look next to fix this.
Thanks

You still might have a suction leak injecting air in the system. Check your fluid for small air bubbles, Over night, the air bubbles should come out of suspension.

Put a hyd gage in the system and check the pump pressure.
