international 574

[tbpo]

When using my log splitter on my 574 international the pressure seems to tail off and although the ram will still move there is no adequate force. I have changed filter and cleaned screen in the hyd. pump which appeared to improve things but it has returned to its old ways. Any ideas?

Do you know what the pump pressure is supposed to be?

Use a hyd gage and check some pressures.

You may have internal leaks in the relief valve, valve spools, cyl, etc.

Are you using correct fluid, and are the filters clean/new, etc?

Sorry for the delay in responding I was away collecting son from hospital and stayed over.
I have replaced hyd. filter and cleaned screen. I have not checked the pressure. It runs very well for a while and thn fades, if I leave it for a while it regains presure for a while before fading again.I will check the presure relief valve next.
Thanks for your help
