Case 444 Hydraulic problems
Posted August 03, 2010 - 08:39 PM
I just got a Case 444 with 3 point hitch. The hydraulics work but I have to really tach it up to use it and it makes a whinning noise. I've checked and topped off the hydraulic fluid with 20 weight fluid but it didn't help. Is this a sign of the hydro pump going bad? Any help would be greatly appreciated. Thanks, Rick:confuse:

Welcome to the forum.
First thing??? Change the hydraulic oil. Install fresh 20W50 brand name motor oil. Don't know how? Then ask.

Thanks for the info hydriv. I'm afraid I really don't know much about that either. Any additional info would be very helpful.
If you have the three-point, then you should also have the optional rear hydraulic PTO valve.
The easiest way to change the oil is this.
Get a nice clean, white plastic bucket that will hold at least 2 gallons. Remove the quick coupler end from the hydraulic hose that is on the rear PTO. Make sure the hose is clean. Put the end of the hose in the bucket. Start the tractor and run it at idle. Shift the PTO lever in one direction. If you chose the correct direction, then the oil will exit the hose. If not, the engine will stall. Restart and move the lever the other way. When the oil stops flowing in a steady stream and begins to spurt air, shut the engine off immediately. Put the coupler back on the hose using some thread sealer and mate the coupler half with the other coupler half to complete the hose loop. Fill the hydraulic tank with 20W50 MOTOR OIL or 15W40 and start the tractor. Try the tractor out and see if there is a significant difference in performance. Report your findings back here.
One more thing. Take a good look at the oil that came out. Leave it sit for a few day and see if any crap settles out of it onto the nice white pail bottom. See. There was a reason why I spec'd that pail.
