Jcb js130 hydraulic pump knocking

mardi 3 novembre 2015

Hi folks

We have a jcb js130 year 2008 approx 6000hrs
We only use it as a backup machine, stock piling stone etc.
Any how a lad was working backing filling a pipeline when it developed a tapping sound from the pump, it sounds like a machine gun and only is noticeable when using boom, bucket or right hand track.

What could it be? And how do we test it?

We have checked the filter for metal but nothing is there. Fingers crossed.

Thanks
