Hey everybody. I was using my 660 to push snow around with a 3 pth blade one day, parked it in front of the shop. The next morning, it was quite cold out, but I started it, and let it warm up. When I came back to it I had no hydraulics. I pulled a hose off the aux spool and pulled a lever, didn't even get a dribble. Thinking maybe I screwed the drive gear or something, I pulled the pump off. The drive gear turns with the motor and the pump turns by hand. There was oil free flowing from the big hole (intake? I presume) in the tube going to the pump. Just wondering if anybody has any ideas. I feel like it is not producing any pressure at all, but I suppose it could be bypassing somewhere too. Where would I check for hyd pressure? Thanks.
