Hydro Ax 611e weak sawhhead: need info on how to check pump and motor

mardi 16 décembre 2014

Can anyone give me info on how to check to see what is causing my weak sawhead? Hydraulic pump or sawhead motor. The saw takes a while to spin up to speed and will only cut a 8 or 10" diameter tree without choking/stalling, then takes 10-15 sec to spin up to speed again. At wide open throttle.

Can the lines be checked with guages? If so what guage, what lines? How do you check flow? I hate to pay for diagnostics on this old machine so I would like to do as much as possible myself.
