My 1st snow fall of the season. 6 inches or so, then rain came in and made most of that slush. I took the 444 out for the 1st time. 

 

I must say how impressed I am with it's overall power. It pushed the snow, slush both up and down hill with ease. 

 

But when I came in the garage, I noticed a leak under the GT. Its hydraulic fluid coming from this cylinder. A small drip every 20 seconds or so. (See attached photo). The clean spot you see was from me, my finger moving the crud out of the way to see if anything was obvious, but I did not see any cracks.

 

I am new to hydraulics, how do I go about fixing this?

Is it where a steel line terminates into a fitting? Or is it where the piston comes out the end of a cylinder?

 

Steel lines would need to be brazed or replaced.

I checked those fittings, nothing. In fact when I went to look just now, I had no drips. I put a clean piece of cardboard under it and cleaned everything off. I'll check in a little bit to see if there are any drips.

 

They did not make it easy to get under there to look.

It will probably only leak when you use it and put it under pressure. You need to clean up that area and then cycle the cylinder so you can find out where it's coming from. If the seal in the cylinder is leaking it may be replaceable or it may be cheaper to look for a good used cylinder.

What I noticed in the picture is what appears to be a wet line at the compression fitting at the right side of the pic, well up inside those tight quarters. It also appears that the pivot shaft is wet with oil too.

I'm going to give under there a good cleaning tomorrow before the next snow fall. That will hopefully help pin point where it's coming from.

With no pressure in the system, I've had no leaks.

Let us know what ya find after the cleaning and a good flogging under high pressure situations.

 

Just keep the oil topped off in the meantime though. :thumbs:

Thank you, what oil should I have in reserve to continue to add?

Just about any oil my friend, just not any " hydraulic " oil, These Case machines run on motor oil, even in the hydraulics.  ( do not run any light viscsity hydraulic oil in yer machine, ever, ) For the motor- straight 30, for the hydro, 15- 30 Rotellla.
