Changing Hydraulic fluid

[Rocksprings]

Another rookie question. When I drain the hydro. fluid.... will all of it drain or will some stay in the lines ? and... At what position do I put the FEL when I drain the hydro. fluid ?

only oil in tank will be drained from bottom plug in tank.....rest of system is confined oil and will need hoses disconnected to be drained....
why do you drain the system?

If just a maintenance so many hour routine, you do not need to get it drained out of lines. If you had a major component failure then you would probably need to clean lines. Observe on reservoir, some tractors have more then 1 area that has a plug for draining. If more then 1 spot, you may leave a little extra old oil that could not drain well. Check owners manual for location(s).

50 Hr Service

The MOST important part of the first 50 hour service is the filter and screen. Just replace the fluid in the sump-no need to worry about what's left in the hoses and such.

I am about to change the fluid and was wondering the same thing. The fluid looks cloudy so I think it should all be drained out so that what is left in the lines and cylinders doesn't contaminate the new fluid. How would I do this?

How many lines do you have? If it's just a loader I would'nt worry about it. if it's got to happen then I would change the oil twice about 10-20 hours apart. It will cost you an extra 30-50 bucks but I would rather do that then break all those line apart.

You can drain the cyl and hoses, but it gets kind of messy. After you change out the fluid, start the tractor, and don't touch any levers. The new fluid will follow a path through the FEL valve back to the 3pt and to tank. If you have drained the cyl and hoses, the new fluid will enter the hose and cyl, and expel the air. You may have to cycle all cyl several times to get all the air out. Then check the fluid level in the reservoir.

Have your bucket all the way back, loader all the way up, and 3 pt up. Tractor off, drain oil, when all out let the 3pt down, let bucket fall down, and then let the loader down without starting the tractor. That should get out all the oil that you can without unhooking everything and blowing out lines.
You well have to cycle all cyl several times to get all the air out. Then check the fluid level in the reservoir.

This sounds like a good plan to me. Unless someone tells me this is a bad idea I will use this method.
