What to do about slow hydraulics on a backhoe?
If jerky, that is a sign of low oil flow and cavitation. If transmission pump flow is good, then I would remove the pressure control valve (priority valve) to see if any of the metal shavings are trapped there. Then flush out the line between the pump and pressure control valve before installing new pump. Click to expand…
How big is the hydraulic screen on a backhoe?
Then I pulled out the cylindrical pre-filter screen that is about 1.5 inches in diameter and 8 to 10 inches long that is inside the main fluid reservoir where a short rubber hose connects the reservoir to the main hydraulic filter assembly. The screen was not damaged and it was clean. I reassembled it.
