Everything worked fine, but every minute or so the Cub made a noise that sounds like a circular saw cutting through a 2x4. I thought maybe it was air but even after several cycles of the cylinder and about a half hour of running, it still did it.

Kefid 200485 A jerky loader function is normally due to air in the loader cylinders, When lowering the loader with weight on it and or at slow engine RPM's the loader going down can faster than the fluid can be replaced in the 'lift' side of the cylinder, when that happens it's easier for the cylinder to cavitate (inhale air instead of the thicker oil) up into the cylinder.

Mar 01, 2012 · like dj54,when you said that it had a loader tank i thought it was a separate pump. since it uses the main pump clean the filter and the filter relief valve.like dj54 said it is in the belly.now it sounds like you have 2 problems.one is a valve is letting the hydraulic fluid drain down and letting air into the system.this will cause the jerking until it warms up and gets the air …

I purchased a 2005 Kubota M105S with 700 hrs on it. The hydraulic system makes a whining noise that sounds to me like it has a restriction somewhere. It sounds like maybe a relief valve is lifting. Not sure! The noise gets louder anytime you activate the hydraulic system - - the front end loader or any of the three remotes.

When the loader was on you probably heard the relief sound when the bucket was rolled completely back. There's the possibility of a malfunction if that's the sound. 3ph's also have a relief valve but it's usually set for higher pressure than the system relief. A weak one is possible and I don't know if the blade is heavy for the 3ph.

Symptoms of Common Hydraulic Problems and Their Root Causes

The pump is the dominant source of noise in hydraulic systems. It transmits structure-borne and fluid-borne noise into the system and radiates air-borne noise. All positive-displacement hydraulic pumps have a specific number of pumping chambers, which operate in a continuous cycle of opening to be filled (inlet), closing to prevent back flow
