I will be doing the work myself, this time, which is why i have all the questions.You have a 1974. So I wonder now if the hydraulic fluid ruined the pump, or if the hydraulic fluid, which is less viscous than the oil, is simply not viscus enough to drive the tractor. The tractor actually engaged forward for a brief second (actually less than a second). As far as I know, the pump was working when I replaced the fluid. As I explained, this time, the flexible hose blew off, and I replaced the fluid with actual hydraulic fluid. So I took it to a different mechanic, and he charged me less than 1/2 of what the first guy did. He charged me a lot to replace that pump - I thought he overcharged me.

The pump he put in gave out when i hooked the rototiller up the following spirng. The first mechanic that changed the pump thought someone had put gravel in resivoir. I have a lot of equipment around the house, including a 1940 ford tractor.

I like the tractor and definetly am not giving up on it. If you're ready to give up on this machine, I might be interested in taking it off your hands. If this thing is broken your pump will not turn. There is a coupling between the engine and pump called a lovejoy coupling, which consists of a pair of round disks with a set of drive dogs on each, with a rubber flex coupling betwen the two. If you've ruined 3 pumps in 4 years you are either using the heck out of this thing, abusing the heck out of it, or have major contaminants in the hydraulic system. As far as bleeding, I've never had to do that when I changed fluid, just keep the lid off the reservoir, let the tractor idle, and cycle the speed and lift controls a couple of times. If you follow the large hose coming out of the bottom of the hydraulic reservoir around the right side and on to the back of the engine, you will see it connects to the pump there. The hydraulic pump is behind the motor, basically right under the battery. Recommended fluid is straight 30 weight motor oil, although some do use a multi-grade motor oil in them. Is that true? If so, where do I bleed the line from?Īlso, can someone tell me where the hydraulic pump is located on the tractor? If that is true, (is it?) have I damaged the hydraulic pump by putting hydraulic fluid in it? Should I drain it and put motor oil in it? If I have to replace the hydraulic pump, do I use hydraulic fluid or motor oil?Īlso I have just heard that I may have to bleed the air out of the line, and that the tractor will run if I do that.

I have since heard that the Case 446 dosen't use hydraulic fluid for the hydraulic system, but instead uses motor oil. The tractor sputtered for less than a second when I turned it on, and it hasn't moved since. I replaced the flexible hose, tightened it, and replaced the hydraulic fluid with hydraulic fluid. The hydraulic hose blew off the resivoir, and all the fluid came out. Recently, something got jammed in the rototiller. Over the last several years, I have had hydraulic problems. I have a case 446, (purchased new in 1983).
