Hi folks. Does anyone out there have any info on setting PRV's /replacing main hyd pump/rebuilding same..... My old girl is a little weary in the hyd. department, and I would like to rectify this, but with workshop manuals slightly less common than peace in Syria, it's a bit of a challenge. Before binning the existing pump, I need to ascertain that it is the pump thats tired, not an incorrect setting on a PRV or a stuck valve etc. Its a triple pump with three test ports, does it need three gauges at the same time, or can I test each section seperately....... any and all info on the machine will be welcomed.

Cheers,

Pete

you would be better flow testing pumps first,i have a manual i will have to look for it tomorrow
