Ford 600 (660) Hydraulics Quit

saskalex · Mar 16, 2014

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.

Theres a few things one might check. With a super cold night one wonders about condensed water freezing somewhere, likely in a return line to the the pump. I know you said you warmed it up, but it might take quite a while for the entire tractor to thaw.

- did the pump lose prime? There should be a pipe plug on the top of the hyds pump closest to the front of the tractor. Loosen a few turns but do not remove. Does hydraulic fluid creep out around the plug, or bubbles?

Good advice.

if oil free flows out the suction line, and you have no remote flow thru a line with no end, then I'd for sure pull the plug on the top o fthe pump and let her run a sec and see what happened.
