460 utility hyd. pump whine

Posted by jwrig43 on June 15, 2005 at 10:36:26 from (24.230.83.103):

I have a cold start hyd. pump whine. I have had a new pump installed, but still makes same noise, but goes away after 10 min. or so. Hydraulics are always working. Wondering what to check for possible oil starvation or air aeration in oil? Or maybe another problem. THanks for any input. jrw
